Oil being poured into a diesel vehicle

If you drive a Dodge, Chevy, or Ford diesel pickup, you know the amount of hard work your truck puts in. You may also be aware that diesels run a little dirtier than your average gas burner. At Repair Masters Automotive LLC in Boulder & Louisville, CO, our goal is to keep your Duramax, Cummins, or Powerstroke truck on the road for many miles to come. A huge part of that is keeping your oil maintained.

It’s easy to skip an oil change - and you probably won’t notice an immediate difference if you do. However, on modern engines with variable valve timing, turbos, and the like, tiny oil passageways can easily become clogged, rendering your engine useless or causing a massive failure. In addition, oil that has reached its capacity as a detergent and absorber of contaminants, it breaks down and loses its ability to lubricate moving parts correctly. Bearing, valve guide, cam, and crank damage begins to occur.

Not to mention, diesel engines work hard - driving conditions and usage have a lot to do with how long your oil lasts. Don’t take a chance on bad oil - keep your truck on the road for hundreds of thousands of miles, by simply keeping it maintained.

Our technicians know how to service diesel trucks, so for the best diesel service shop in Boulder & Louisville, CO, call or stop by Repair Masters Automotive LLC today. Our technicians would be glad to answer any questions you may have.
