Frequently Asked Questions

Our team of skilled technicians is ready to share their expertise. Should you have a question about automotive repair or maintenance, please contact us directly, or explore our FAQ page, where we address some of the most common inquiries about our services.

Q: How often should I change my oil?

A: Regular oil should be changed every 3,000 miles. Synthetic oils should be changed every 5,000 miles. However, not everyone drives the same or has the same requirements. Ask our professionals to review your driving habits. Regardless of oil change intervals, your oil level should be checked regularly. Feel free to stop by, and we will check it for you as a courtesy.

Q: What should the tire pressure be on my car?

A: Tire pressure should always be set by your vehicle manufacturer’s suggested PSI (pounds per square inch) specifications. These specs are listed on a plaque affixed to the driver’s door jamb. Feel free to stop by for a courtesy air pressure check.

Q: How often should I check my anti-freeze?

A: Checking your anti-freeze every month is good practice. Level is important, but so is the anti-freeze concentration level and freeze point. Let us check that for you at your next visit.

Q: How long do spark plugs last?

A: Spark plug life depends on the type of spark plugs in your vehicle. Vehicles made before 1980 typically have standard plugs with a life expectancy of 12,000 to 15,000 miles. Models made from 1980 to 2000 usually last 30,000–50,000 miles, and 2001 and newer model vehicles come with plugs that can last up to 90,000 miles or more.

Q: How often should I change the timing belt on my car?

A: Every vehicle is different, and while the common mileage intervals are 60,000, 90,000, or 105,000 miles, it is important to know when yours is due. Failure to replace the belt at the proper interval could result in severe engine damage. Refer to your owner’s manual regarding exact mileage details for timing belt maintenance. If you are unsure of your replacement needs, please call, and we would be happy to check for you.

Q: When should I change/service my brakes?

Q: When should I change my rotors?

A: You should change your rotors every 50,000 to 70,000 miles. When you start braking, and the vehicle shakes, that is a sign of a warped rotor. This shaking usually happens at higher speeds, starting at 40 mph. You should bring your vehicle in to have the rotors checked and/or replaced.
A:
  • You should change your brakes every 10,000 to 20,000 miles.
  • If an indicator light comes on in your dashboard.
  • If you feel any shaking or vibrations in the brake petals.
  • If you notice the brake pads are less than ¼ inch thick.
  • If you start hearing your brakes squealing, you need to have them checked immediately.
  • When there is a leak in your brake line, it usually leaks onto the tire and onto the ground, eroding your tire in the process.
