Yep Rotella is good on the cheap. Royal Purple is good to :biggrin:
10-40 probably not 20-50 where you live

in 2007 the zinc in oil drop dramaticly
i will use the new shell rotella next spring but i will
add that product in

GM EOS assembly lubricant (PN 1052367), currently sold in a 16-ounce plastic bottle, is an excellent concentrate for breaking in a new cam. Your favorite cam company should offer a similar product. If running API SM/GF-4 street oils, consider adding a 4-ounce bottle of GM camshaft and lifter prelube (PN 12345501) at every oil change to protect in-service flat tappets.

hope it help

Funny little story.... went to autozone to buy some rotella-T.... the guy at the counter asked "for what kind of car", i go "84 buick regal t-type"...he goes "you dont want to use that oil, its a diesel oil, you'll want to use castrol synthetic." So i go "i didnt come here for your opinion, can i have what i asked for?" and he goes "sure, but i dont want to have to tell you that i told you so." I go "Well...thats why you work here dude."
