anyone know why engine oil goes black in some subaru engines and not in others . reason i ask is the oil in the 08 legacy gets changed every 10k klm from new with no hard driving and its always black coming out like its being in there for years .
the last 07 legacy the oil use to be nearly the same coming out as going in . using mobil 1 in all engines. the 95 legacy seems to be the same with the oil being clean only 1000 miles since oil change .

anyone have any reason for this :ponder:
