What we don't know is the replacement additive that's used in Low SAPS. Just saying "less of X means more wear" is silly if X is being supplemented with better and more expensive Y. This is why it's silly to use UOA's to determined the "strength" of the add pack.

Is there any definite reason why the ACEA "C" oils are BETTER than an established excellent 229.5 oil like M1 0W40 in an application that doesn't call for them? Charlie
