It's Official-- Red Line over Royal Purple for the Rear Differential

[Cadeez]

Glad I came across this thread... I'm actually going to change my diff fluid this weekend, which Redline fluid do I use? There's so many different kinds of Redline gear oil to choose from; GL-4, GL-5, MTL, MT-90, 75w80, 75w90, etc... Any guidance would be much appreciated, thanks

You sir...are the MAN! Thanks again for the info, this is great

I wonder if this is the case for M3 differentials as well? I am going to swap the fluid in my M3 diff but I was just going to use the OEM fluid they recommend. I guess I have some research to do now to see if it is worth going to a non-OEM fluid choice for the M3

Looks like the M3 gea roil is different, they list Redline 75W140 GL-5 Gear Oil. Check this link out, it's pretty specific

Thanks for this Keith...

I was just talking about Redline vs Royal Purple today with a coworker. He has a Mini Cooper and needs to change his Auto Trans fluid. I told him go with Redline oil, but he just bought some Royal Purple.

OEM always seems to be a cafe choice. I opted for Red Line based on ease of acquisition and Old School Maintenance approval.

Yes. LSDs need the 140 w/additive, iirc

Thanks for the help guys, looks like this is a better and cheaper option for the M3 diff

Aww shucks, thanks Dane, glad you chimed in! You should know I'd never cheat on you (guys)! Haha. I know I'm not around much anymore, but when I need some good friendly info, there's no family I'd rather turn to. I've got a full weekend of work ahead of me, so this is probably not the last you're gonna hear from me either.
