my engine builder broke mine in with joe gibbs break in oil he buys it in bulk no stores around me carry it,my local advanced auto has the lucas break in addative i add it at every oil change that might work for you the comp cam stuff is good to but its mail order. 30wt should be safe.
i looked it up on the zones website but they arent showing it here. i just need to go down there. i could order it but i wanted to just get it all in one stop. i will look for the lucas as well, i hear that is great stuff. i know they have the VR1.
