Oil changes are integral to the performance, longevity, and reliability of your diesel truck. At Harold's Used Auto Parts Inc in Philadelphia, our expert mechanics understand the importance of good quality oil, changed at correct intervals, in allowing you to get the most out of your Cummins, Powerstroke, or Duramax diesel.

Diesel trucks require specific oil, and typically a lot of it. Your run-of-the-mill bargain oil change won’t typically cover the amount of oil your truck requires, nor will the quality of oil satisfy your needs. Diesel trucks work hard, whether it’s on or off-road, meaning the quality of the oil that goes into your engine is especially important. We offer a wide variety of oils, including several brands, viscosities, and high mileage applications.

While diesel engines are generally more reliable than gasoline engines, they do have specific needs. Diesel engines are inherently dirtier engines, and dirt and oil buildup can become an issue quickly if regular service isn’t maintained. Couple that with the hard-working nature of diesel trucks, which spend a great deal of time hauling loads or in harsh environments, and you can see why keeping up with oil changes and using high-quality oil is essential.
