Let me start by saying - whoa, this site is insane. I didn't think I ever wanted to know so much about oil/ additives but can't stop searching.
Subject references my '86 F250 with 351W and 4bbl Holley 600CFM. The truck has just under 100k and she is very good shape for being a New England truck her whole life. She is a weekend worker for me - hauling wood, dump runs, HD runs, plowing my drive and some neighbors, etc. My guess is it gets 1500mi/yr.
She sees the highway, but pretty rarely; and the longest she ran with me was 1hour each way, when I hauled my plow back home.
What oil would you recommend? I'm afraid of using a synthetic based on the engine's age but am open to suggestions. Her first change by me was Valvoline 10W-30 although next winter I'll have to find a 5W-30. I did have my wife pick up some Rotella T at Wally World - but semi-synthetic has me nervous.
