Oil Change Question for my 28.5
I'm changing the engine oil and am not sure about deisels. The engine is a 2GM20F. What type and weight?Shell Rotela 15w-40 rated at CE,CF,CG,CH,CJ,...
WM carries it.Terry
Tom:The primary thing to look for is the rating of the oil. Oils have a S rating for Spark type ignitions (gasoline) and a C rating for Compression (diesel) engines.I like Delo too, it is typically easy to find so it is almost like a standard and is most always available.
