AR oil

[water dog]

I have been using marvel mystery oil on my engines and was wondering if tranny fluid might be better ?.I have seen insides of trannys that didnt have any rust at all.Tranny fluid is pretty cheap too.

Yes you can! Some have been using it for years with no problems that I have ever heard of. The only thing is that it does not burn off like others, so you need to flush the engine before starting. NO BIGGIE...........

If you have a LHS just pick up some AAR oil... 2 bucks for the bottle...

I used to use marvel mystery oil.... I swear the after run oil and marvel mystery oil are the same thing... they smell the same....

I would just continue to use MMO or pick up some AR oil.
