Oil viscosity ?

Well, Argo is probably right on everyone having a very strong opinion on oil...given that we all know how important it is to an engine's well-being, this stuff is bound to get people worked up (it's like bringing up national security or child-rearing practices...yeesh!).
Anyway, I appreciate the discussion and the tech/images Slaya offered. I noticed I was going through more oil than I expected last season, and I run Royal Purple 5w-20. Since I generally feel pretty good about Royal Purple as a manufacturer, I'm not happy with this weight under extended track use (same as the OP's stated use). I'll probably switch to 10w-30 next season.
Best,

I've also had consumption issues with both Mobil1 and Royal Purple in another vehicle. Switched to Redline in that vehicle and the consumption issues ceased. Amsoil Sig Series 0W-30 level in my 07' mustang barely moves on the dipstick over the 10k mile changes (don't track my car or really even drive it that hard and live in a dry climate). I attribute minute loss to crankcase ventilation through the intake. I'm sure I would see that lost oil in a catchcan, if I ran one....
