Complete Diesel Service Provided

Because of their efficiency and durability, diesel engines have become the standard in powering our nation’s passenger vehicles, pickups, and other work trucks and buses.  Diesel service technicians who service and repair these engines are using more complex diagnostic equipment as diesel engine maintenance is becoming increasingly more complex with engines and other components using more electronic systems to control their operation. At R & M Automotive in Rockvale, our team of expert diesel mechanics is qualified and ready to work on diesel trucks and have the experience you want behind that wrench as well as the passion for truck repairs.

Our diesel mechanics handle a variety of repairs on the Ford, Chevy, Dodge & GM trucks that come into our shop making them exceptionally versatile in their knowledge base and when you combine that with the diagnostic equipment they have access to it is hard to beat their expertise. Diesel repair is becoming increasingly complex and requires a certain skill set and that versatility comes in handy with a diesel technician who knows what they’re doing.

What service do you need?

Your diesel engine is very different from a gas engine starting with the way it gains power using compression in the combustion chamber to ignite the fuel versus a spark like a gas engine. The real key to keeping that diesel engine in top shape is filters and with regularly scheduled maintenance and fluids - specifically diesel engine oil, exhaust treatment fluid, power steering fluid, coolant, brake fluid, automatic transmission fluid, rear differential fluid. On 4×4’s, you also have transfer case fluid and front differential fluid. It is more than you need on a gas engine but the durability and power you get with diesel are worth it and the routine maintenance will save you thousands of dollars in repairs easily.

When do you need to schedule maintenance for your diesel engine and what is needed each time?  For your convenience, we've added the preferred maintenance listing:
