Mercury Auto Service in
Whitewright, TX

At Grayson County Diesel in Whitewright, TX, we take pride in offering expert service for Mercury vehicles. If you drive a Mercury, you already appreciate its balance of comfort, reliability, and performance. Whether you're in for routine maintenance or a major repair, our shop offers a dependable, high-quality alternative to dealership service departments—without the dealership price tag.

From quick oil changes to full engine work, our team handles every job with care and precision. We stand behind everything we do because our work is performed by certified technicians with the experience and training to deliver results. We know Mercury vehicles inside and out—from the Milan and Grand Marquis to the Mariner, Mountaineer, and more—and we’re ready to help you get the most from your vehicle.

Keeping up with regular maintenance is essential for protecting your investment. Over time, fluids degrade, parts wear out, and small issues can turn into major problems if left unchecked. That’s why we focus on preventative care to keep your Mercury running smoothly mile after mile.

We also believe car care should be simple and stress-free. When you come to Grayson County Diesel, we’ll work with your schedule, keep you informed, and make sure your vehicle gets exactly what it needs.
