I like Corvettes, but when I worked in the Chevy dealership about 80% of the Corvette owners were a complete pain in the butt to deal with.

I’ve spent quite a few hours on the internet reading about ZDDP, additives, and which oil to use. I’m more confused about it now then before all of the reading. It seems there are a bazzillion different opinions on it. Between my wife and I, we have four vehicles with flat tappets. I can’t decide which oil is best to use.
