Not that I doubt you but do you have proof? My buddy picked up a GTI and is super anal. Uses Castrol because its whats in the bay. I’d love to show him proof of M1 being the better oil.
MOTUL 8100 X-cess 5W-40 for me.
I’m on my phone but you can find the MSDS sheets for both oils as well as virgin oil analysis for both of them on BITOG.
There is a rebate for M1 right now.

Makes it $33.40 for a 5.1 quart jug.
good stuff, 10qts plus two filters and my leftover oil should hold my jeep over for another year or two
