Specific Gravity of Diesel Fuel VS Motor Oil
The reason for the question is....in the event of an injector not closing properly and letting fuel leak into the cylinder will diesel fuel float on motor oil or is it reverse?
Forum Discussion
I suppose I was thinking about a cold engine and checking the dip stick when I posed the question. Crankcase seems to show above full reading since the last outing(maybe a qt). No milky substance. So, probably not antifreeze. My question is, what is it and where did it come from. Was not there before last trip.
