1)I bought some lower end oil and was gonna add to the level of oil ,took the bottom plug out to put in a treaded pc. from the pump put it wouldn't go in(couldn't get it to thread) so I didn't go any further....not knowing how much is in there I let some oil out, I 'm thinking that shouldn't pose a problem, after this weekend from the lake i'm gonna drain it figure it out.
2) just wondering if you can use gear oil ( 90 w) for your lower end oil.
