You'd think they'd put the MRV on there, but, No, they don't. It's weird, they must have the spec so why not include it for people to see?

M1 Super High Mileage 5w/30 came in at 26,400 at -35C.
MSS 5w/30 at 20,500 at -35C.
Where did you find this info, I looked all over for it?!?!

I'd expect the 5w/30 HM MRV to be similar to their regular M1 5W/30 (in the low to mid-20,000's at -35C).
You then have to make a conversion from -35c to -40c to "compare" to any of the 0W grades.
What's this conversion you speak of?

I didn't even realize there were different versions. I already have the 5W-30HM but was thinking maybe I should just run a 0W-40 instead, but wanted to know for my temp range (-5F to say +30F) which actually flows better. The 5W-30HM I have is SN.
