So, just to be clear Dave, you're saying 'make sure I don't order the one in my SECOND LINK? This is the stuff Motorworks are selling.

Let me join the list of confusion then because the advice has changed since my original purchases. :-

2020 I bought transmax 75w90 castrol and that was longlife transmission oil but returned it and purchased their Castrol Syntrax, as their recommended bevel drive/gearbox oil. (opieoils)
Somewhere on an earlier forum I was advised not to buy any other bevel oil and if the dealer uses it then I will copy.
I had just had my R1200ST bevel unit rebuilt (good job at Oceanbmw Plymouth) and was reinstalling it myself.
Again I was advised to make sure I got the bmw recommended Syntrax castrol as they supplied it back to me 'dry' after overhaul
Now I see some sites are now advising using Transmax 75w90
Look at opieoils.co.uk and the advice has changed!
Maybe the specification has changed but as of today they have this update

DISCONTINUED - Castrol Syntrax Universal Plus 75W-90 Fully Synthetic Car Gearbox Oil

This product has been replaced or superseded by:

Castrol TRANSMAX Universal LL 75W-90 Fully Synthetic Transmission Fluid

Like I say 'confusion' but if that is the latest update and the oils specifications are now correct for the drive unit/gearbox I guess I will now buy Transmax75w90

I now change bevel oil every year in the RS and every two years in the ST now (it's a longer job) but currently it has had 3 oil changes since rebuild just to be safe.

Haven't been down to Oceanbmw in two years since the ST brake fluid change (needed again now) but now everything is opening up I will get it, and the RS, brake fluids done by them.
Perhaps I will confirm the current advice, (Castrol for ST engine, Shell/bmw for the RS and hopefully the same for all bevel/gearbox uses.
Mileage is so low last two years I have been home servicing and bikes have been on battery tenders. Spent more on oil and filters than petrol but hopefully that changes this year!

Beemer Boneyard is another option. Liqui-Moly products. But in the link, they also reference Maxima as a substitute.

I’ve used Amsoil Sever Gear oil and have been quite happy with results in my K16 and RS. Not cheap but solid stuff, imo
