delvac
I have a 85 6.9 diesel, Im running 15w40 rotella and am thinking about switching to Mobil delvac heavy duty oil 15w40. Anyone have opinions? Also I want to run the fleet guard oil filter but I can not find the long one so you can use an extra quart of oil. anyone know where to find the tall fleet guard oil filter?
