Yes, it does. Did mine tonight, following Marco's excellent how-to. I realised (after refitting everything and lowering the car) that I had overfilled. Two 950ml bottles of Redline MTL is 1900ml, so I should've had about 300ml left in one bottle. There wasn't that much, maybe 100-150mls.

I jacked it back up, using the front jacking point on one side and the rear jacking point on the other side. This allowed me to lift the car more 'level' until there was just enough room to wriggle under. Dropped the undershield and removed the filler plug, and about 150-200mls drained out. Wiped clean, put everything back again. Mental note to remember elementary geometry in future....

Did mine today (130i LE) following this guide, nice and easy.

I couldn't get a syringe so bought a small transfer pump for about 7 quid..I was worried once I had the old oil out, this thing wasn't going to pump it back in....but it worked a treat!

My choices for gearbox and diff oils are...

Diff oil.

Gearbox oil.

http://www.opieoils.co.uk/showproduct.a ... ission-oil&" onclick="window.open(this.href);return false;

Think they will be good enough and correct grades etc?

Also wondering what sizes the diff and gearbox washers are, as I think just changing those is enough instead of new bolts.

I went for redline and I'm pleased with the results still 7-8k later.

I think next time I will try the oem oil and see what the difference is like.

I did mine on the weekend. The car was on ramps on the front and axle stands at the rear - it looked level but wasn't, being tilted down at the rear. This meant I could get more oil in the gearbox than required. If you overfill you can create more drag and maybe foaming issues, so I got the car level and the same happened as in the above quote. It was the diff that showed me it wasn't level - as I undid the diff plug the oil came out...

The existing diff oil wasn't too bad and still yellow. The gearbox oil was black and free flowing. Car has done 100k+ so maybe the diff oil has had a change at some point or it doesn't get too bad.
