Hey guys,

What would be the best oil to use in my e39 M5's gearbox? I think I need a change.

Thanks in advance.

I'm using Transmax M, its decent for the manual boxes.. but I know everyone gets their onderbroeke in a knot when it comes to choices of oil.. so ya I dunno.

Royal Purple is the gearbox oil of choice on the M5board. There is even a sticker on the Gearbox that says not to change the oil ever. But from experience Royal purple does a better job than the original oil.
