Message I've been doing UOA since 2009 using Mobil 1 0W40. I've always had low viscousity readings for the 0W40, definitely below the expected average. I've also had fuel present in my UOA which kills visc... none reported since the switch to 15W50.

With the 15W50 sample, the visc readings are within grade and wear metals are acceptable as well. The first UOA with no warnings or unacceptable ratings... and this after a season of hard road course running:

Will do another one after next change, as this is the first one on the new grade. I'm sold.

GASOLINE AND MONEY

wondering how you set your climate control to 22* lol, it
would be that fastest freezer on wheels!
