Just an update. Not sure if it’s the increase in viscosity or the amsoil flush that freed up my rings but im 1200 miles in and I’m barely 1/4 quart down. Been driving more conservative on the max life 5w30 change so far but had a couple high rpm highway runs and the level is holding up.
I’m thinking about staying with this oil and filter combo maybe just going with the tough guard instead of the extra guard. I want to go back to syn so I can maybe run 6-7k ocis from here on in if possible though. Does it make sense to go to switch to syn maxlife? Or I was thinking about trying out the super tech hm full syn. Any advice?
