technical/repair help 2018 i3s rex gearbox oil
Hi everyone, inspired from this subreddit i’m going to service my bmw i3 electric motor gearbox. The dealer said I need g3 hypoid oil so I have been looking about as I don’t really want to pay £50 for 500ml when I need just over that (filling through the drain plug). As far as I believe FUCHS is the OEM for the oil and they don’t seem to sell 70W-80 G3 GL5 to the general public but I have found it for sale on bmw motorbike suppliers. I know people use Febi Bilstein but I have used FUCHS in the past and also the product sheet seems to say fill for life approved which sounds oddly familiar to what bmw says.
