Reasons Your Car Won’t Start

There are many reasons your car won’t start.

There are few things worse than the feeling you get when you put your key in the ignition of your car, turn it, and… nothing. Silence. Probably more aggravating is when your car does make sounds like it’s going to start – it’s trying, it’s turning over, chugging, coughing. It just won’t catch and sputter to life.

Here are a few of the most common causes of your car not starting.

Starting with the starter…

A bad starter might lead you to think that the battery is weak or nearly dead. If the starter pulls more current than the battery has, it will turn slowly and make a “GRR, GRR, GRR” cranking noise, which sounds a lot like a weak or dying battery. If you hear a lot of grinding, that’s the starter, and it might be damaged – either the fly wheel or the teeth should be checked. If the starter doesn’t even respond, its relay or, solenoid might be burned out. The ignition switch could be the culprit, too.

That is what many people immediately assume. It is indeed one of the most common causes of a car refusing to start, but a dead battery doesn’t mean a completely bad battery to be thrown away. It just means the battery doesn’t have a charge, and it might be that another component has failed. There are a lot of ways to knock out a battery.

  • Forgetting to turn off the headlights.
  • Door/courtesy light has been left on (door ajar, switch set to on).
  • Defective interior light generally unnoticed – trunk, glovebox.
  • Dirty, corroded battery terminals, or low battery water.
  • A defective, failing charging system that does not recharge the battery (see alternator).

Of course, batteries do get old and start to fail. Most have a life expectancy of about 3 to 5 years, depending on quality and your driving habits and conditions. Batteries have to work harder in cold temperatures, and usually show signs of failing when the weather turns cold.

The alternator has failed and nothing is getting any electric love.

If the alternator has died, the battery has not been getting a return on its output and has not been charging. When the car is running, the charging system (alternator, voltage regulator) should recharge the battery and provide sufficient electrical power to the vehicle. The battery then serves merely as a backup. If the vehicle requires more electrical current than the charging system can provide, the battery picks up the slack. This can happen in extremely cold weather, particularly if you’re stuck in traffic and it’s snowing or raining. You’re constantly starting and stopping, brake lights are constantly on, headlights on, heater, defogger (which usually is accomplished through the air conditioning), interior dash lights, devices like smart phones being charged, radio on, possibly integrated wireless, phone, Bluetooth, onboard computer, entertainment, internet/satellite/cell service connections. It all takes electrical power. The alternator has a pretty tough, thankless job. The battery just sits there!

If the starter can crank the engine without a problem, then the battery and alternator are probably fine.

So, the engine cranks fine, but won’t turn over and go.

When you turn the key in the ignition and the engine cranks normally, but won’t catch or fire and start running, this means the battery and alternator are working as they should, and the problem lies elsewhere. If you keep cranking the engine, the battery will eventually run down and need to be recharged. So, what else could be wrong? Determining where or what might require a trip to a mechanic, but here are some things to be aware of.

Image - mechanic fixing fuel pumpThe fuel pump has conked out.

Here’s another component with a dirty, thankless job. The fuel pump sits in the gaseous darkness of the gas tank, pumping fuel the length of the car to the engine. A malfunctioning fuel pump can give different signs of imminent failure: faint whining, chugging or sputtering at high speeds, chugging or lack of power during acceleration, noticeable loss of power and performance, unexpected surging, and of course, an engine that won’t start.

Out of gas?

If the fuel pump is operating properly, then maybe you’re just out of gas. Check the needle on the dash. In some older cars you might have to turn on the ignition for the needle to register, but you shouldn’t have to start the entire engine. Of course, if the battery is dead, then checking the needle is not an option.

Cold weather and ethanol can cause problems.

Sometimes in cold weather, ethanol that is mixed in the gasoline can cause water vapor condensation in the fuel tank or fuel line. In cold weather, this water can freeze and cause blockages in the fuel line. Keep your gas tank at least half full during the winter to avoid this problem.

Your car might just need a tune-up.

It’s easy to forget about more simple, smaller parts and processes that happen in the engine. Spark plugs are a good example of things that often go overlooked. A thorough engine tune-up will address any basic operational issues, including spark plugs, timing, air/fuel mixture, and other things that can affect your car’s ability to start and run reliably.

Signs of Bad Fuel Injectors

Is It Time for New Fuel Injectors?

A fuel injector is part of your vehicle’s fuel system. Fuel injectors are the component that spray the fuel into the engine. These are controlled by the vehicle’s engine computer (ECM), which controls how it sprays fuel into the engine, following purposely timed intervals and patterns that help optimize the engine’s efficiency and overall performance.image of used, dirty, fuel injectors.

Symptoms of a Bad or Failing Fuel Injector

There are many things to look for to determine if your fuel injector is failing in some way or needs to be replaced. Since these are a part of the fuel system, it’s important to watch for these symptoms to determine if the fuel injector is bad or failing.

Engine Performance Issues

Often, when a fuel injector is clogged or starting to fail, you will experience engine performance issues. These types of issues can include everything from engine performance issues to strange smells – all of which your local Minnesota AAMCO auto repair center can diagnose.

Check Engine Light Comes On

A bad fuel injector can cause too much or not enough fuel to be delivered into the engine – this will cause the Check Engine light on the car to turn on, indicating an issue. Your trusted Minnesota AAMCO auto repair center can help decipher your check engine light and figure out what issues need to be addressed.

Vehicle Won’t Start or Struggles When Starting

If the fuel injector is not delivering enough fuel to the engine system, this can cause the car to struggle when trying to turn over or not turn over at all (just cranks with no result). This can also cause the engine to stall due to the air-fuel ratio not being correct.

Vehicle Misfires

This can occur if your engine is not receiving enough fuel from the fuel injector – which stems from fuel injectors being clogged and dirty.

Poor Idle

You will notice a rough or choppy engine idle when the car is not moving. It might even feel like the engine it going to stall every time you stop. This can be caused by the fuel not being properly injected to the engine cylinder.

Engine doesn’t Reach Its Full RPM

If too much fuel is being injected into the engine, this can cause the engine to surge. This will make it feel like your car is jumping forward quickly but struggling to fully take off. You may also notice a loss in power or acceleration. 

Smell of Fuel

Another symptom of a failing or leaking fuel injector is a fuel odor. Because fuel injectors hold high amounts of pressure, and over time they can begin to leak around the seal at the tip of the injector or nozzle. A leak from either of these areas can affect engine performance – most noticeably fuel efficiency – and will give off the smell of gasoline. If you begin to smell gas fumes, you should take your car into a mechanic as soon as possible to avoid any further damage or safety hazards.

AAMCO Can Help with Your Fuel Injector Repairs & Replacements

image of new, clean fuel injectors ready to be installed.Because fuel injectors are one of the main components for an engine being able to run – by providing fuel to the engine – they are extremely important to the overall functionality and performance of your vehicle. If you start noticing any of the previously mentioned symptoms, or suspect that there could be some issues with your fuel injectors or any part of the fuel system, schedule an appointment with a professional mechanic to diagnose the problem and provide next steps for how to fix it.

Tips for Affordable Car Maintenance

Save Money & Time With These Easy Tips

Maintaining your car so it is safe and reliable doesn’t have to cost a lot of money.

image of car speeding around bend on country road with sun shining through trees.

Having a car can be fun, and it definitely makes life easier, but when it starts to malfunction or break down, it can be a costly hassle and a safety issue. Your car can cost a lot of money if you don’t run a regular maintenance schedule. Making sure that maintenance is affordable and easy is important in our go-go-go world. Luckily, there are some things you can do to ensure your car is running smoothly and safely, without breaking the bank. Here are some handy tips and information on some simple, affordable things you can do to help your car run better and last longer. Grab a coupon and save some money with these local Minnesota AAMCO specials.

Get to know your car – read the owner’s manual.

Read and pay attention to the owner’s manual for your car. Don’t have one? Check with your local dealership or go online – there might be a PDF version you can grab, load to your phone and have with you at all times. No matter what car you drive, the regular maintenance schedule should be spelled out in the manual. Old myths like “Change your oil every 3,000 miles,” will go right out the driver’s side window. Of course, if the manual says you should change the oil every 3,000 miles, then do it – but we bet it doesn’t say that.

You’ll discover how often your manufacturer recommends to change the oil for best performance and reliability, as well as even what kind of oil to use. Your owner’s manual will also enlighten you on many other aspects of your car and the things that should be regularly maintained – such as the all-important transmission fluid, filters, timing belts, hoses, battery, lights, and fuel types. All of this information is available in the car’s owner’s manual.

If you’re part of the TLDR crowd, then just consider this: you’re throwing away good money by not taking care of your car, and to do things right you have to educate yourself. Most car owners know how important it is to know at least a little about their cars, but even if you’re not interested in how your car works you should know a little about it, otherwise you run the risk of being taken for a ride with some shady mechanic (more on that later). Knowing some simple things, like the right kind of oil to use, for example, can save you trouble in the long run. Even knowing what kind of fuel is best for your car is really important and can save you a lot of headaches – and money – if you just know. Doing the wrong thing or treating your car poorly might run the risk of voiding your warranty or even worse – causing damage that requires expensive repairs.

Sure, these days we can just pick up our smart phones and holler questions at it and get quick answers. Good, solid answers that provide you useful information that helps you make good decisions can be hard to come by, though – even in this day of information access (and overload). If you want to know more about your car or are concerned about its performance, or why it’s making weird noises. why your ride is bumpy even on smooth roads, or if you know you need repairs, call your local Minnesota AAMCO auto maintenance and repair center.

Check and Change Your Oil

Old story, been handed down from campfire to Facebook – but oil is vital to the successful operation and long life of your car’s engine. Checking the oil is a good habit to get into. Even if you think everything is fine, it’s a good idea to check it when you stop to get gas. It’s easier than it sounds. Pop the hood (you do know where the hood release lever in your car is, right?), grab some paper towels (usually found with the windshield squeegee around the gas pump), pull the dipstick, wipe it, put it back in, pull it back out, and see where the oil meets the fill line. If it doesn’t meet the fill line, it’s low. Repeat the steps and check again, but if it’s still low you should take your car in for a checkup to find any potential leaks or areas that might be eating or burning oil.image-hand-of-mechanic-holding-white-rag-with-oil-dipstick

Also pay attention to the color of the oil. It should be golden and clear. If it’s dark brown, a change is in the near future. If it’s black and/or thick and gooey, it should be changed as soon possible – don’t wait! Modern cars will tell you with an electronic warning light when it’s time for that regularly scheduled oil change you read about in the owner’s manual. Keep in mind that checking the oil after the car has been running might not give you the most accurate read on level. You’ll want to double check once the car has had a chance to cool down and sit a while. This gives the oil a chance to recollect in the oil reservoir, which will give you a more accurate read on its level – and you can get a better read on the color, too.

Go beyond oil and learn how to check other important fluids in your car.

Even if you don’t know how to change your antifreeze, power steering, transmission, or even your wiper fluid, you should learn how to check them and which ones to top off, which ones to have changed by a mechanic. Wiper fluid – don’t let someone charge you for this, unless it’s part of a larger package deal. That is so simple, it’s painful to think of paying to have it done.

For many fluids you can see the tank level directly, but most have gauges or dipsticks that help you check the levels. Even if your owner’s manual doesn’t provide much information or guidance about checking things such as your transmission fluid or coolant, don’t be afraid to educate yourself. Go online and find answers, or just open the hood and look around. See if you can find the right tank, cap, or dipstick (they’re usually labeled to some extent). If you’re running low, add more fi you can, or schedule a maintenance appointment with your trusted mechanic. If you notice a leak of some sort, definitely take your car in for diagnosis and repair.

Check the battery and make sure it’s clean and good to go.

Check the battery for signs of corrosion, and generally keep it clean and clear of debris. Make sure any terminal convers are secure and clean, and clean the terminals if necessary. Most batteries these days don’t require much manual maintenance, but you should know where the batter is and check it from time to time, usually along with the oil. This will help you ensure it’s not leaking and there is no corrosion or crud building up on the contacts. If there is, clean them with a battery cleaning brush. The brush doesn’t cost much and it’s a quick, easy thing to do. Also consider getting a simple battery tester or jump starter. Using these, you can monitor your battery and know when it needs to be replaced before it leaves you stranded. You’ll never have to call or wait for roadside assistance.

Get your timing and serpentine belts replaced when necessary.

image of engine with serpentine belt

The engine timing belt is usually replaced every 60,000 miles or so, and the serpentine belt about every 40,000 miles. Again, your owner’s manual is the authority on this. These are really important parts that can make or break the engine. If you don’t have the owner’s manual, look online to get this important information, or call your local Minnesota AAMCO. If you’re just not sure, or know that it’s been a long time (or never) since you last even thought about that serpent timey belt or whatever it’s called, schedule an appointment and ask your mechanic to inspect all belts and hoses and replace them if necessary. You just don’t want to let them fail. It is not only a matter of having a safe and reliable car, but if you wait and those belts do fail, your car will break down, possibly leave you stranded or in an unsafe place – and leave you with costly towing (if your mechanic doesn’t do it for free within a certain mile radius). It can also damage other engine parts and systems, making repairs even more expensive.

Rotate and balance your tires, check the alignment.

Tire rotation and balancing is often overlooked by drivers. It does take time, you always have to battle a long line, and it’s just never convenient (when is any car-related maintenance or repair convenient?). Once again, your trusty owner’s manual will tell you how often to rotate the tires. It’s important to make sure your tires wear evenly and your car drives smoothly, not only because your fuel efficiency is directly affected by these factors, but your safety is, too. The saying that you’ve got a lot riding on your tires is true! You can make your tires last a lot longer by having them rotated and balanced. Along with that, your alignment is just as important. If you’re fighting to keep your car driving straight or having trouble safely navigating curves and turns, it’s time for an alignment. Alignment also affects the wear of your tires. Bad alignment will cause serious wear and tear on your tires, risking flats and, even worse, blow outs which can be dangerous or deadly high speed.

Change the spark plugs.

If the spark plugs are worn out or covered in crud, your engine is not running efficiently. This alone can cost you a lot of money in fuel, and it can lead to a breakdown. This might be a little more technical than you’re comfortable with, but in many cases checking and replacing the spark plugs is not that difficult. If it’s something you just don’t want to do – especially if it’s complicated for your vehicle, just follow the recommendation in the owner’s guide. Take your car to your trusted mechanic and get those spark plugs changed on time – usually around 30,000 miles for standard copper spark plugs, but it can vary.

Find a Reputable Repair Shop with Certified Mechanics

Finding a mechanic you trust is important, and sometimes not easy. It can take time, and might involve some trial and error, as well as, unfortunately, some money in the process. If you’re lucky, you’ll find a mechanic who is honest, trustworthy, tells you like it is, and doesn’t do any repair work that is unnecessary – and definitely not until you give the OK.image of smiling AAMCO mechanic tipping his hat.

Some Causes of Smells Coming From Your Car

5 Things Your Nose Can Tell You About Your Car

Besides that new car smell, there are fairly few odors you experience in or around your car that are pleasant. Your nose knows when something is foul or amiss. Some smells are pretty telltale of a certain condition, while others might present a little more mystery in need of investigation. Here are five odors that are indicators of potential problems with your car.

Hot or Burned Oil

The smell of hot or burned motor oil could mean that a gasket or seal is failing. This lets engine oil leak onto hot engine parts. Additionally, a leaky transmission seal can cause oil to spray all over the engine, including the manifold. These hot engine parts burn off the oil, creating bluish white smoke that wafts from under the hood.

The first thing you should do is check the oil to make sure it is at the correct level and that it’s clean. Small leaks often become bigger leaks, so check under the car, on the pavement where you park, and around the engine for signs of leaks. If your car is running low on oil, the engine can overheat and burn whatever oil is remaining.

If the burned oil smell is coming from the tailpipe (bluish white smoke), it is a symptom of oil leaking into the combustion chamber, which means it is getting into your exhaust system. The oil is burned in the combustion process with the air and fuel mixture, and pushed out through the exhaust system. The exhaust system is one of the hottest systems in your car, dealing with the noxious byproducts and fumes of the internal combustion engine banging away under the hood. If oil leaks into the either the combustion or exhaust system, it is going to be burned. This is usually a sign of an old, worn out engine in need of some serious repair and regular maintenance.

GasolineAAMCO Minnesota Vehicle Bad Smells

If you smell gasoline, like when it’s pumped at the gas station, inside or outside the car, you should take special care to identify the source. It is likely a sign of a gas leak in the fuel line or fuel injection system (if your car has one). A leak in the fuel tank vent hose oftentimes is the culprit behind gasoline odors inside the car, especially after filling the gas tank. At worst, there could be a leak in the gas tank itself.

In older pre-1980’s cars, the smell of gasoline can occur after the car has been turned off due to fuel afterboil. This is often normal and results when a small amount of gasoline continues to burn in the carburetor after the engine is shut down.

Any persistent smell of gasoline, either in the car or outside of the car such as in the garage, should be taken seriously. Any smell of gas fumes can indicate a fire hazard, so it should be checked immediately.

SyrupAAMCO Minnesota Bad Smelling Car

If you detect the scent of maple syrup, it probably means there is a leak in the cooling system. Cooling fluid is leaking onto hot engine parts and being burned away. If there is a leak in the cooling system, you need to check the coolant fluid level, check for leaks in the engine compartment and on the pavement in the areas you park (such as driveway or garage). Left unchecked and repaired, you will risk overheating the engine and causing major damage.

A syrup smell could also mean the engine coolant is boiling after you have turned off the engine. This is due to the inability of the cooling system to dissipate engine heat, so the engine remains extremely hot for an extended time even after it has stopped. If you decide to investigate, wait until the engine has cooled off! Never remove the radiator cap while the engine is running or is still hot. It will cause a massive blow off of superheated fluid that could cause serious injury.

Rotten Eggs or Sulfur

This wonderful stench means your car is in need of a checkup and that the catalytic converter is having some serious issues. The catalytic converter is in the car’s exhaust system and is supposed to convert noxious hydrogen sulfide to sulfur dioxide in the exhaust fumes before they exit the tailpipe. If this is not happening, it means that your engine needs more than just a tune-up, and the catalytic converter could completely overheat and fail, leading to costly repairs.

Burned PaperBad Smelling Exhaust Fumes

If you smell something like burned paper, it could meant that your clutch is overheating. If you’re riding the clutch pedal, it creates excess friction between the clutch facing and slips. The material between these surfaces is made of a paper compound, which gives it its familiar smell.

The smell of burning paper could also mean your brakes are overheating. Riding your brakes, such as when coming down a hill or mountain, creates unnecessary friction and excess heat on your brake pads. You might also have a seized up brake piston, resulting in a “dragging brake.” Or it could be that you just left your parking brake on. In some cars it is easy to forget and actually drive with the handbrake still engaged.

 

AAMCO Minnesota Can Help Sniff Out and Fix Problems With Your Car

We realize that in order for one to understand some of this, you must know what the “smells like” really smells like. If you’ve never had maple syrup – get thee to a pancake house now – you’ll likely not know what to sniff for. Whatever the smell, if it’s not new car or the scent of that air freshener you just bought to battle the gym socks and mildew in your car’s air filtration and circulation system, then you should come to AAMCO Minnesota for a multi-point diagnostic inspection.

Exhaust Smell in Your Car Can Be Due to Different Things

image - dual chrome exhaust tailpipeThe car exhaust system neutralizes the harmful fumes that come out of the engine. It is important to have your car checked out if you start to notice any odd odors or exhaust smell inside the car, as this can mean some major problems in the exhaust system or engine. If you experience any eye irritation, or you notice a smell like rotten eggs, a sweet smell or an odor of gasoline, you should have your car checked as soon as possible. Bring your car to a local AAMCO Minnesota auto shop for a complete inspection and diagnostics.

How a Car’s Exhaust System Works

Exhaust Header or Manifold

The exhaust header, or manifold, makes it easier for the engine to push exhaust gases out of the engine cylinders. In cars with fuel injection, the oxygen sensor is mounted in the exhaust header and is controlled by a computer. If the oxygen sensor is faulty or has failed, the computer can’t calculate the air/fuel ratio, so it “guesses”, which affects the engine’s performance, and this can affect many other systems as a result. If you are experiencing a strong smell of gasoline as you drive, the oxygen sensor is one of the first things to check.

Pipes

image - exhaust manifold

The exhaust travels through connected pipes until it exits through the last one – the tailpipe. These interconnected pipes throughout the system do more than just help the exhaust move; they cool the pollutant gases and guide them through the catalytic converter.

Catalytic Converter

The catalytic converter changes the harmful carbon monoxide and hydrocarbons to water vapor and carbon dioxide before they exit through the tailpipe. This reduces impact on the environment because the elements being emitted from the car have been broken down into more basic forms. Some converters also reduce harmful nitrogen oxides. If the odor you are smelling is that of rotten eggs, then the catalytic converter is probably failing. The rotten egg smell is because the converter is not breaking down the sulfur pollutants created by the engine. Catalytic converters can’t be repaired – they must be replaced.

Catback

The “catback” is a system of pipes between the catalytic converter and the tailpipe. These pipes, running along the bottom of the vehicle, experience a lot of wear and tear, including harsh temperatures, damage from obstacles, rough roads, and exposure to weather which can lead to rust.

Muffler & Tailpipe

An internal combustion engine runs by creating controlled explosions, so it makes a lot of noise. You don’t hear most of this noise because the muffler, if it’s doing its job, reduces (muffles) the noise to a low level as the exhaust leaves through the tailpipe. The muffler also sees a lot of wear and tear, along with the tailpipe, as they constantly go through heating and cooling between extreme temperatures.

Exhaust System Leaksimage - Mechanic and customer looking at exhaust system under car on lift

Exhaust leaks can occur in many places along the line of all the interconnected parts that make up the exhaust system. If you smell the exhaust inside the cabin of the car, the leak is possibly somewhere near the air intake vent, under the hood. The leak might be somewhere in the exhaust pipe system that runs the length of the car, or even in the muffler, but the smell won’t be so powerful. Hydrocarbons are processed in the catalytic converter, which is located behind the engine, near the exhaust manifold. So, if you smell any exhaust, it’s probably escaping, or leaking, before it reaches the converter.

Causes of Exhaust System Leaks

We’ve all seen it – a rusted muffler riddled with holes laying in the middle of the road. It fell off someone’s car, and chances are the entire exhaust system (maybe the whole car) looks like that poor, old muffler. That’s why it is important to have the underside of your car visually inspected from time to time.

Internal Corrosion

Internal corrosion is a major cause of exhaust system leaks, and is the main cause of system failure. When moisture condenses in the system, it reacts with the iron in the steel, causing acidic buildup and rust. This can eat right through the metal of the pipes, muffler, and other vital components of the exhaust system, causing leaks, structural weakness, and operational failure.

External Corrosion

External corrosion is caused by weather related road conditions. Depending on where you live, during the winter the roads might be treated with chemical deicers, salt, and sand. All of this, combined with the snow, ice, and harsh temperatures, really beats on the underside of your car – and that’s where the exhaust system is. The constant barrage of different compounds, including plain old water in the form of rain, snow, and ice, gradually eats away at the various parts of the exhaust system.

Driving Conditions and Habits

Where you live and the road conditions around you dictate much of the wear and tear on your car, particularly the exhaust system. Rough, dirt roads obviously will have a higher degree of impact on your car overall than smooth highways and city streets. Additionally, how you drive those roads is a factor. Short trips versus long hauls have different effects on your car’s systems. Whether you speed along those bumpy, dirt roads or are constantly stuck in stop-and-go traffic in the city – it all adds up to things like extreme heating and cooling, debris causing damage, and stress to systems that are not the exhaust system, but that can affect it. As mentioned earlier, if the oxygen sensor goes out, the engine will burn too much fuel, too hot, which can affect the exhaust system and cause undue heat to pass through.

What Happens if You Skip Oil Change

 

What Happens When You Skip Oil Changes?

The much-repeated saying is that you should get your oil changed every 3,000 miles or three months. On modern cars that use synthetic oil, the limit is much higher. Skipping those oil changes, no matter how frequently (or infrequently) your owner’s manual says they are needed, is a recipe for trouble. Going a long time between oil changes (thousands of miles past the due date) is like playing with fire.

Engine Oil Checkup

Here’s why oil is the lifeblood of your car…

image - mechanic laying under car draining oil into a pan.In order to help them diagnose what is ailing you, a doctor will have you go to the lab to have blood drawn and analyzed. The lab will run it through a bevy of tests to determine how you compare to a baseline on certain things, and what might seem out of the ordinary. Basically, the condition of your blood gives the doctor clues to your overall health, as well as to more specific things.

Engine oil can be analyzed and used in the same way to help diagnose problems, or explain trouble symptoms, with your car. For instance, high concentrations of iron indicate that steel engine parts, such as the camshaft and cylinder liners, are not properly lubricated and wearing out. Metal content collects in the oil, and the oil filter eventually becomes overwhelmed and incapable of filtering the metal out of the oil. Traces of other metals in the oil can indicate the need for an oil change – and possibly other repairs. Chrome indicates ring or gasket wear. Aluminum is from pistons and bearings. Silicon might be dirt, and means the air filtration system should be checked.

Of course, you should not wait so long that such an analysis of the oil is what it takes for you to realize your car is in desperate need of an oil change. With the evolution of engines, the general rule today is every 3,000 to 10,000 miles.

Oil Lubricates and Cleans the Engine

What does engine oil do and where does it go?

Oil is a lubricant and prevents metal engine parts from coming into contact with each other. If parts do come into unintended contact, the engine can overheat and eventually the metal parts wear out, break, or even melt. Oil contains detergents that lift out contaminants and carry them to your oil filter, where the dirt is filtered out of the oil.

What Happens When You Skip Oil Changes Pouring oil into the engine is one thing, but do you know where it goes or what parts actually get lubricated? Check out this image that shows the parts and areas of the engine that the oil runs through, lubricates, and protects.

Oil eventually wears out and needs to be changed.

Oil is subject to consistently high temperatures and breaks down over time. Sludge can form throughout the engine, making it difficult for oil to flow between moving metal parts. Viscosity modifiers also break down over time, which makes the oil thinner and less effective at lubricating moving parts at high temperatures. Also, metal, dirt, and other particulates build up in the oil, much of which is too small to be captured by the filter. Over time, detergents and additives meant to combat the contaminants and dirt will break down become less able to protect the engine. The oil becomes abrasive and speeds up wear on vital parts and systems, and shortens the life of the engine.

Get an Oil Change

You can prevent all of this by – you guessed it – flushing out the crud with an oil change. If you don’t change your oil and oil filter, eventually the filter will stop working and dirt will accumulate in the engine, contaminate the oil, and compromise its ability to lubricate and clean. Over time, even the best oil will lose its lubricating and cleansing qualities. Because of all the dirt and abrasive crud in the oil, metal engine parts will experience severe wear, risking failure and potential damage to the engine. Eventually, the whole engine will seize up and stop working, maybe even catch fire.
