Emissions aside, do full SAPS oils tend to protect an engine better? I know there is likely no definite answer to this...just curious. I run a full SAPS oil in my truck (m1 0w40) and the UOA results show far less wear metals in the oil than the universal averages. The kicker is that i run a 10k oci and universal averages on the 6.2 are shown for 5k. I also plow with my truck and live in a very cooooold neck of the woods.
Just curious as to why my numbers are different.
