Q: What is preventative car maintenance and why is it important?
Preventative maintenance includes things like tune ups and oil changes. Preventative maintenance is one of the best ways for you to save money, avoid unnecessary costly repairs, and ensure the long, reliable life of your car. Regular maintenance involves a thorough check over of all the systems in your car, to make sure that everything is working correctly or identify areas where problems may occur before they become costly repairs. Be sure to take advantage of our seasonal specials – we typically offer free safety checks!
Q: How often does my car need a tune up?
Typically we suggest that you get a tune up around every 30,000 miles. Unless you car was made before 1970, and then more frequent tune ups are recommended. Regular tune ups can help to lengthen the life of your car, as well as alert you to problems before they happen, saving you time and money in the long run.
For the most accurate information for your specific vehicle type, please refer to your manufacturers recommendations.

Q: How often should I get an oil change?
Oil in your car breaks down over time. Sludge can form in the engine, making it difficult for oil to flow between moving metal parts. We suggest an oil change every 3000 – 7,500 miles, depending on the age of your car, unless otherwise specified in your owners manual to maximize the life of your vehicle. Learn more about our oil change services.
Q: How often do I need to replace my timing belt?
Most cars need to have their timing belts changed every 80,000-100,000 miles, unless otherwise stated in your owners manual. This is very important as the belts inside your car wear down over time when the timing belt breaks it will throw all of the parts of your engine out of sync, causing it to seize up and stop running. This can cause rods to blow through your engine block, along with other massive damage. Learn more about the warning signs of a failing timing belt.
Q: How often do I need to replace my car’s fuel filter?
We suggest changing your car’s fuel filter every 30,000 miles unless otherwise stated in your owner’s manual. Other signs of bad fuel injection can be detected in this useful guide here.
Q: How often should I have my alignment checked?
Typically this will be done once a year during a regularly scheduled oil change or tune up. We suggest about every 10,000-12,000 miles to maximize the life of your tires.

Q: What does the check engine light mean?
Your car is made up of many systems and components. Think of it as a “warning sign.” When this light comes on, it means that there is an issue with your engine, emissions, and sensors. Even though your car is running “fine” it is recommended that you don’t prolong a check-up.
Q: My engine oil looks like chocolate milk. Is this ok?
That “milky” looking oil is a clear sign that your coolant is mixing with your oil. When something like this occurs, it is time for an oil change and more. Often, this is a sign that you may have some cracks or head gasket leaks. It is best that you get this checked with a professional mechanic as soon as possible.
Q: How often should I replace my brake pads?
Depending on the type, brakes begin to wear at 20,000-30,000 miles. However, not all brakes pads experience the same amount of wear. This is very dependent on how you drive and your environment. If you notice that your vehicle is taking a long time to arrive at a complete stop, hearing grinding, or screeching, it is time to come in for service. Servicing your brakes routinely is the key to saving you money and keeping you safe.

Your muffler also is responsible for absorbing/suppressing the sounds coming from the engine thanks to the design and materials located inside it.
