E82 125i oil for diff and gearbox

Post by dennis3258 »

Looking for some details and advise on what oils would be ideal for the breadbox and the diff of my car.
I have looked in to it, but couldn't find a "best" option.
Can anyone give me some useful advice on this?
The car is a completely original 2008 BMW E82 125i with manual 6 gearbox and 33107591014 differential.

I used Redline MTL (very popular aftermarket option) for the gearbox and Castrol Syntrax 75W90 (OEM BMW fluid) for the diff.

Don't forget to buy replacement plugs, they have built-in nylon crush washers so might not seal back up. Should be about £7 each from Cotswold, or £10-20 each if you go for aftermarket magnetic ones (which is a good idea!).

Thank you for the information, that should be valuable.
I must apologise as I am a bit late with my reaction, have some thoughts about the rear end of my car.
