I do drive about 50% "spirited" at mid to high rpms.
I run Mobile1 5w-30 oil and filter but plan on switching to AMSoil OE grade 5w-30 next time around. On Subaru 2.5i N/A motors it's actually recommended that our cars run 0w-20 oil if using a full synthetic blend... I don't bother to run that thin of an oil but, do any of you?
