Gents,
I'm sure this has been beaten to death over the years. But I'll open the can of worms anyway. A friend who just got a 1968 Z28 asked my opinion and I myself have different notions in my own head, but it's a relevant question for our old cars.
What do you use for oil in an older high performance engine? I use synthetic with a Zinc additive. But who says I'm right? I've heard Rotella and other things as well. I'm interested in your opinions.
Thanks.
