Frequently Asked Questions

Here are some of the most common questions or professional mechanics receive at our Gaithersburg auto mechanics shop. If you don’t see your questions here please do not hesitate to give us a call!

What type of Vehicle’s do you service?

We Service all makes and models.

Do you service Brakes?

Yes, we can replace your brakes. You should always have a certified mechanic give you a full evaluation of your braking system to see which components are worn out, should be replaced.

Do you do oil changes?

Yes, and we can change your oil. We offer standard, synthetic blend, and synthetic oil to service your vehicle. Which ever oil type your vehicle manufacture requires we can take care of it for you.

Do you do MD State Inspections?

Yes, we have certified state inspectors at each location. Fun Fact, You only need to have your vehicle inspected one time when titling it in the the state of Maryland. If you sell they vehicle to another person down the road, then the new owner will have to complete another Maryland State Inspection.

Will my vehicle warranty be void if I have you service my vehicle?

No, You the consumer has the right to take your vehicle anywhere to have it serviced. You do not have to take it back to the dealer for your services. The consumer is protected by the Magnuson-Moss Warranty Act, passed by Congress in 1975.

How much air should I put in my car?

Whatever the door sticker states. This manufactures sticker is called the Placard, and will identify to the vehicle owner the proper tire pressure for the front and rear tires. Important, do not fill the tire to max pressure located on the sidewall of the tire. The Manufacture has done many tests to verify the proper tire pressure for the vehicle weights, size, and control. Remember Firestone and Ford Controversy back in 2001? Trust the placard.

My oil life says I have 17% of life left should I replace it or wait til 0%?

The oil life monitor in some vehicles are not accurate based on the condition of the oil inside the engine. In some cases, the oil could be completely worn out, or still be be good to go. The oil life reminder usually looks at drive tie, temperature, and mileage to give an educated guess. If you want to maintain your vehicle stick with 5,000 mile intervals for synthetic oil changes, and 3,000 mile intervals for standard oil changes.

Do you have change the filter when changing the oil?

Yes, The oil filter is an important part that removes grit and grime from your oil. This prevents such contaminants from entering the engine itself when oil circulates and lubricates its parts. Stay in the same routine and change the oil filter when you change the oil. It’s only a few extra dollars but it will save you thousands if damage were to occur for not replacing the oil filter.

How much does a brake job cost?

It Depends. We would love to give you an answer on price that is accurate or close to accurate as possible. The issue is there are too many components that could be worn out that replacing the brake pads, or resurfacing/replacing the rotors may not be sufficient in making the vehicles stop and safe on the road. There are other components to consider, and you need to have a certified mechanic give a complete brake evaluation to give you an honest estimate. However, depending on the vehicle, year, make, model, series, age, type of rotor, typ of pads, a good guess would be $150-$1000 on average.

When should I rotate my tires?

Simple to maintain your tire warranty, and maximize the tread life and usage of the tires, rotate them at every 5,000 mile oil service. If you do not rotate your tires frequently you can expect un even wear which can cause poor handling issues and safety concerns. Bottom line, rotate every oil change.
