Can any confirm the spec of gearbox oil for my Z4M Coupe as i wish to change it, I think its the same spec as E46 M3, I think it should be 75/90 gl5 just want to be sure i am putting right stuff in, Thanks
Can't confirm the spec but I had mine and the Diff changed a week or so ago for the first time since new; 35k mls. I can't believe the difference it has made. Slick 'snick' perfectly weighted gear changes.
