Happy New Year All, I am going to change the Diff oil in my 318is, how much do i need to buy to fill up to the filler plug. Any tips on doing this job. Thanks

318iS has a small case diff from the factory so it'll take 0.9litres.
If it's a normal open diff it'll need SAE 90w hypoid gear oil, if it's an LSD it needs a special oil available from your BMW dealer (you need to take a 1litre container with you) or from our oilman (
www.opieoils.co.uk).
If you're unsure which type of diff you have, jack up one rear wheel, leave the gearbox in neutral and take the handbrake off, spin the jacked up wheel by hand. If it's easy to rotate you have an open diff, if theres substantial resistance to rotation you have an LSD.
Cheers,
Iain T

Small case LSD takes 1.1 liters. filled mine a few months ago. Or is the open diff different?

Hi!
I've just bought the BMW LSD oil from my local dealer, and payed ┚¬72 (£50) for 2 liters!
Part number is Z9100970005 and is graded 75W140!

Always open the fill bung first on something like the Gearbox/diff

£50 for 2 liters is a rip off. £20 for 2 from oil man

Yeah, you're right, but I'm a good couple of thousand miles from oilman (Portugal), and postage costs would makes things even.
Plus, I need it for yesterday. But thanks for the tip!
Next time I need, I'll quote him for sure!
