you cant go wrong with german castrol. autozone is the only place the carries it. go to your local store and ask them to order some, they usually do. if not, WS6store sells it by the case. royal purple and amsoil are also good.
if you insist on using M1 5w30, i have about 8-10 qts. that i will give to you free of charge.....thats what i think of using M1.

I must say thanks again to Ron for the offer on the Mobil 1 oil. I picked up the oil at his house last week and we shot the breeze for about one hour. Great deal for me and it was much appreciated!
