hello! what kind of oil should i use on motor "detroit serie 60". gearbox fuller 13 speed. and diff on my 1992 kw w900l?
whatever kind you want but most people use the mobil delvac 15w40 engine oil in a Detroit. 50w synthetic in transmission and 80/90 or 85/140 gear oil in the rears (synthetic)
i like the mobil delvac myself, but everyone has there opinions on oil and i don't think any properly rated oil is going to do any harm.
