Differential Oil

Post by e21Keith »

I'm wondering what oil to use in the diff of my manual '81 323i (non-LSD)/

My Haynes manual says SAE 90 Hypoid gear oil but it doesn't seem easy to get hold of. Any other recommendations?

Just 9 listed in the UK.
Yes I can get it, but do people use anything else that is perhaps a bit more modern and maybe a bit better?

demon tweaks sell motul gear 300 synthetic, making many claims.
No experience of this but I believe synthetics generally superior, modern engines don't wear out like they used to.
Anyone used this?
