Hi, Do anyone have recommendation from their experience on what brand fluids would you recommend for transfer case and differential fluid change? I read few posts from bimmerpost where Ravenol was recommended. Any thoughts? Thank you
Offhand I'd suggest BMW OEM - I've always like Redline for differentials, might take a call or a little research to ensure you choose the correct one - limited slip vs not, for instance. Unsure if same would work for transfer case. In any case, a high-quality synthetic, whatever you choose. Not familiar with Ravenol, although I haven't been up much on fluids options as of late.
