Yea that makes sense but I also really like magnatec 10w-40 so I dunno I guess I'll decide when it comes it'll probably come down to what's comes on sale first haha but it doesn't really say anything completely along those line Tim rebuilds "compression" which in my case it did "compression" repair which in my case it did hahaha you just gotta think about how they write it dad used to be a mechanic and only bought snap on and good tools so I'm guessing it's pretty good but hahaha I will if you get the chance I'll be happy to use urs! haha
