Mobil EP says back of container virtually removes all sludge in one oil change.along the lines of that. I know Mobil one is no longer a true synthetic. Like amsoil SS,redline...
What ingredient or ingredients are in EP to do all that cleaning? Does it have extra calcium like 0w40 European formula does? Does it have alot if esters like synthetics do? What does Mobil EP have in it,that states on Thier product it virtually removes all existing sludge,..but not being a true synthetic?
