My oil reports show m1 above 800 and redline above 1200 for zinc. To me that's like saying your cat will last only 33% longer if m1 is used. But since most cats last over ten years I could care less so far down the road.
What I do care about is m1 has almost no moly! Moly is the best protector of an engine period. M1 is 99 and RL is over 700! To me my bearings and vvel are more important than my cats. Also m1 is like water! I'd never use it again in a motor that runs hot and I'd never use it in a gtr with turbos. My WRX hated the m1 and the thin water would leak through the turbo seals. RL 5w40 stopped that from happening. RL FTW!
9300 miles was m1, the other 2 were RL 5w30. The reason for fuel in the last test was oil was changed without me warming the car up because I forgot.
PS!!! This was with a k&n filter! So people bitching about how they don't filter well can pound salt.
