BMW change to recommended Final Drive oil

[Grumpy Goat]

I was at my local dealer the other day, Cycle Werks in Barrington IL. The parts guy Dan told me that BMW are changing the recommended final drive oil for all their bikes. Instead of the Castrol SAF-XO, which costs about $23 a liter when I bought it a while back, BMW are now recommending something else. I can't remember what the new oil is called, and I did not take a photo of the bottle he showed me. On the MAXBMW fiche the recommended final drive oil now shows as HYPOID AXLE OIL G3, so I'm guessing that is it. The price on the fiche currently say N/A.
Dan told me the price is $80.00 for half a liter. Yikes! Must be some magic stuff.
I see some selling it online for $70.00 per half liter.

Maybe it fixes the shaft / yoke / spline issues that may or may not happen.

A quick Google search shows prices as low as $49. Still pricey.
