Frequently Asked Questions

Have Some Questions? We’re Here to Help



How often should I get my oil changed?

Most vehicles need an oil change every 3,000 to 5,000 miles, depending on your make, model, and the type of oil you use. Synthetic oils can often go longer between changes. Always check your owner’s manual for manufacturer recommendations. Keeping up with regular oil changes helps prevent engine wear, improves fuel efficiency, and can extend the life of your vehicle.


Why is my check engine light on?

The check engine light can turn on for many reasons, ranging from something simple like a loose gas cap to more serious problems with the engine, transmission, or emissions systems. Even if the car seems to run fine, it’s best to have it diagnosed right away to avoid turning a minor issue into a costly repair.


How do I know if my brakes need to be replaced?

Warning signs include squealing or grinding noises, a brake pedal that feels soft or spongy, vibrations when braking, or the vehicle pulling to one side. You might also notice longer stopping distances. Addressing brake issues early not only keeps you safe but can save money by preventing damage to rotors or other components.


What should I do if my car starts overheating?

If your temperature gauge is rising or you see steam from under the hood, safely pull over and turn off the engine as soon as possible. Let the engine cool completely before checking coolant levels. Avoid driving while the engine is overheating, as this can lead to severe and expensive damage like a blown head gasket.


Can I bring my own parts for repairs?

Some repair shops allow customers to bring their own parts, but policies vary. Keep in mind that using your own parts may affect warranties or guarantees on the work performed. It's also important to ensure the parts are a correct fit and of good quality to avoid future problems.
