If its not an Automatic, do not use ATF.

If its a manual, some 75w90 is probably fine.

I used heavy-weight lucas oil on mine. It was expensive.

If you have an auto, call royal purple and ask if they recommend the usage of that fluid with your transmission...or wait for someone with a better answer than me.

Neo. None better, IMO.

put 75W90 in the tranny unless it's a slushbox.

I generally just use 75-90 Amsoil synthetic. ATF is for automatics, so unless yours is, you need proper gear oil.
