Texaco MT94 is the only approved oil for that gearbox. it is a lifetime fill oil (lifetime of the gearbox, get it......?) You really truly do not need to change it but if you insist any synthetic gear oil, the lighter the weight the better, will do. The European spec you want to ask for is, I believe MT-1.

Transmission oil change-Not
While oil can be changed regularly or even before the normal service interval, the transmission fluid should not be changed unless there is reason to change like the installation of a Quaife LSD, light weight flywheel or racing clutch.
Also the fluid used should be MINI spec and not other brands even though one would think that redline should be OK. I spoke to eric at Helix13.com and he said that a mechanic for MINI that he worked with says that it is best to just stick with the MINI spec transmission fluid. I would think that if you didn't use the MINI spec fluid that using another fluid would void your transmission warranty as it might affect gaskets, etc.
Oil is a little different, I think as long as you use the factory spec weights and use a fully synthetic oil you don't need to use Castrol brand.

I changed mine at 4000 miles and used Mobil 1 90wt full synthetic. I now have 34000 miles with no problems. Personally, I think you can use any quality synthetic of the proper wt and it will be fine. Getrags are used on a lot of different cars and I can't imagine they used special seals for this particular model that would only hold up to BMW-specific fluid. I'll probably change mine again and use Redline MTL. But having said that, I truely don't think you NEED to change the fluid.

Why????
Why would you want to create more service for yourself. If there was any, even the slightest reason, possible that you needed to change your tranny fluid then beleive me BMW/Mini would tell you to do it. Thet make $$$ on service, peroid. If they say that you dont need to do it then they are prob right.
Save the $$$ for the very expensive oil changes.

There are dozens of motor oils approved for the MINI.

Two answers.......
to MINIRACER 03......I just noticed no one has answered you. If you look at the gear box (Cooper S) on the left side around where the axles jut out, you will see a series of nuts or bolt heads. Two of them are a different color (black) and have small hex head indents in them. the lower one is the drain plug and the high one is the fill plug. Same should hold true for the Cooper.
to RESMINI.......I hardly doubt MTF94 is NOT synthetic. fill for life means incredibly high oxidation stability. Only synthetics afford that kind of longevity. go to chevrontexaco.com, products, sear for a PDS...should tell you.
dollahs to donuts it is synthetic and more than likely manufactured in Painesville, Ohio, USA........

No one has asked the question, "why do you not change gearbox oil as often as you do engine oil?"
There is a very good reason. The crankcase of an engine gets dirty from the byproducts of combustion. Moisture, acids and other contaminants, even in an engine in perfect condition build up and can eventually destroy the engine if not cleaned out. If there were no oil contamination, there is no telling how long the engine oil would last. Draining it is the only method we have to clean the engine internals.
Modern engine oils have very effective additives that clean all of these contaminants out of the engine when you drain the oil. BTW, if you drain the oil right after shutting down the engine, more of these contaminants are churned up in the oil and drain out with it.
A gearbox, on the other hand, has no combustion process going on (you hope.) Thus, the only "contamination" that can take place is from metal particles that occur from normal wear, or maybe someone grinding gears. Many gearboxes have a magnetic drain plug to contain these metal particles to prevent them from causing wear.
If you want to do something for your gearbox, make sure it has a magnetic drain plug. If it does, changing the gearbox oil every 50,000 miles or so for peace of mind would probably be way more than adequate.
Good luck.
