A diesel engine requires specific diesel oil to run properly. Diesel oil is specially formulated with a higher viscosity and more additives to deal with the size and increased combustion pressure of a diesel engine. If your diesel engine is running hot or if you notice a burning smell, be sure to check your oil. Keeping your diesel oil fresh and clean is one of the easiest ways to prolong engine life. At O'Reilly Auto Parts, we carry heavy-duty diesel motor oil, oil additives and oil filters to help you maintain your diesel engine.
