Rotella T has Zinc as well if you can find it at a truck store. And its alot cheaper then the Name brand shit. All I ran in the dragster until I sold it to Southern.

not anymore from what I've read.

rotella no longer has the same amount of zinc in it anymore. Remember les its been a pretty long time since you had the dragster running. Lol. Some of the newer batches of kendall 20w 50 has the increased zinc in it ( or at least thats what the the rep had said when i called him. Otherwise any gm dealership should have the additive. Its called EOS assembly lube or something along the lines of that.
