May Service Tire & Auto has been taking care of oil changes for Warrenton and Warren County drivers for over 30 years. Conventional, synthetic, and high-mileage options are available on all makes and models. Schedule service today.
Conventional Oil Change
The straightforward choice for older vehicles or drivers who keep their mileage on the lower end. Reliable engine protection at a price point that makes sense for everyday driving.
Full Synthetic Oil Change
Better protection, longer intervals, and improved performance in both extreme heat and cold. If you want the best for your engine and fewer trips in for oil changes, full synthetic is worth it.
High-Mileage Oil Change
Formulated specifically for vehicles over 75,000 miles. High-mileage oil helps condition aging seals, reduce oil consumption, and keep older engines running cleaner for longer.
Conventional Oil Vehicles
Every 3,000 to 5,000 miles. If you are doing a lot of short trips around Warrenton or stop-and-go driving, staying toward the lower end of that range is the smarter move.

Full Synthetic Oil Vehicles
Every 5,000 to 7,500 miles and, in some cases, up to 10,000 miles depending on what your manufacturer recommends. Synthetic oil holds up better under the kind of driving conditions Warren County roads can throw at it.


At May Service, we take a few extra minutes to make sure the job is done correctly, check your tire pressure, top off your fluids and take a quick look at your vehicle while we have it in the bay. If we spot something that needs attention, we’ll tell you about it honestly and let you decide what you want to do. No pressure, no upsells. Just a thorough oil change from a locally owned shop that has been doing this in Warrenton for over 30 years.

How long does an oil change take at May Service?

Can I go longer between oil changes with synthetic oil?
Yes. Full synthetic oil generally lasts 5,000 to 7,500 miles and sometimes up to 10,000 miles depending on your manufacturer’s recommendation. We’ll let you know the right interval for your specific vehicle when you come in.
