Thanks JeePete. Read around a little this week and found out the same thing, most of the kits come with the additive to make the oil compatible, so I'm just gonna get one of them and do it up. Couldn't find it in Wal-Mart, but found some online, found one kit in JC Whitney for like $53 with all of the things you'd need. Just gonna get that one and see what happens.

Thanks again.
