I use discount auto parts oil, quaker state, Valvoline, whatever is on sale. After running the engine with forged pistons, hedders, holley 650, and street/strip cam for 17 yrs I decided go to a wilder cam and so took the engine apart. And yes I drive the car hard and race it from time to time. Everything inside was fine. Cylinder walls looked good, bearings were all great.
My theory, use decent oil, not bulk oil @ $.50/quart, change it every 3000 miles and everything will be fine.
I do use a Ford oil filter. Used to be a tech with Nissan and saw some blown engines on cars with Fram filters. Never saw it happen on an American car. It's too long to write out why this happens, but suffices to say I use factory filters on all my cars including a 626 Mazda with 150000 miles.
