So I'm going to run this in my Accord. I like the M1 specs. VI 180, zinc and prosperous levels are around 1100 mark, nice for a little more wear protection with vehicle at 118k. I have used PP before but a 0/20 What I cannot find is detailed specs for PP only their typical advertising stuff. The other thing I like is both are ACEA rated. I feel their specs are better than API. Honda UK says to use ACEA A3/B3 or A5/B5. And API SM.
Weights as follows
0/20 best MPG
