Freaked my Dad out today over oil
Ok so I've searched through archives and looked at other sources online before posting this question. Seems to be a bit of controversy.
Today I was talking to my 63 y.o. Dad about another thread I have going right now about cams, flat tappets and the whole zddp shenanigans and how there isn't that much protection on older motors. Well my Dad has several engines he's concerned about all the sudden. Most everything he owns are flat tappets. Scratch that- everything he owns besides for his new truck are flat, including a straight six 55 chevy truck, 53 Chevy belair, 64 impala 283, and (I'm guessing Flat) 84 caprice 305.
Somehow the whole zddp thing evaded him. He is now wondering if he should add an additive like Lucas to all his oil changes or if there is a better way. He won't go to synthetic oils on these, FYI. I'm sure he'll stick with conventional.
I'm sure he'd switch brands of oil as long as it wasn't too expensive.
