Penzoil Ultra PlatinumI'm sorry, idk what PUP stands for?
as for temps, I’d prefer between 230-250 under hard load in high ambient temps.
I've thought about the same thing, but am uncertain if it is beneficial or necessary. I'm certainly no oil expert. I track in Georgia, Florida and Alabama, so we get some pretty significant heat as well.Yeah same here. Done a lot of research and can’t find a reason to change weight yet. But next track session going into the summer here in TX with these temp I am strongly considering moving up to at least a 40 weight.
