    Hey guys. another great oil question. The original manual says run 20w-50 oil. but i hear alot of guys run rotella 15w-40. is that conventional?? the t6 i think is synthetic right?? has synthetic been proven to be a
    good choice for these motors?? I like to keep it simple, and since i still have a leak going on that i have not
    fixed, i would like to go the cheapest route for now. thanks
