So, at the time, I made the cautious decision to go with G2 from the dealer for the front diff since there was a good chance that's what came in the car *AND*, particularly, the G1/2 series of fluids appeared to be GL-4. I thought it said GL-4 on the bottle too, but current pictures online show G2 coming in a bottle marked GL5. At the time, I could find NO information on G2 except by buying a bottle at the dealer. The thing that REALLY threw me for a loop was that G1 is GL4 (I incorrectly stated in a recent thread that G2 was GL4). The front diff had only G1 or G2 listed (G3 didn't exist). Whenever you see SAF-XO that means pretty much any quality 75W90 GL5. My rear diff had a number of fluids specified, including SAF-XO and Synthetik OSP. There was differing info in different parts systems, and the local dealer parts manager and the parts/service liason had a lot of trouble figuring things out as well with what was published in parts systems for my VIN at the time. I have an 2011 F10 X-Drive and I had a really interesting time going through differential lubes before a change a couple of years ago. I'm just looking for someone that might know or understand the REAL reason?īeen digging into a couple of things, and I am going to later post a correction in another current thread in which I recently posted about this. And why drop the weight to 70W80 for the rear?ĭo you think that they have done this to be more GREEN? That would be a better MPG from a lighter fluid OR less harmful chemicals to the environment? Why can't I just use a 75W85 GL5 fluid like Red Lines 75W85? It's a good grade GL5 & the same weights as the G2. My question is Why would they (BMW) change from the standard 75W90 GL5 oils? Is there that much difference in these newer fluids? It's even higher if you purchase from a Dealer. 5 liters of each, which is $280 just in gear oil. Rear Differential with a G3 fluid, which is a GL5 70W80 $80.49/. When I go to the BMW Tech site & FCPEuro, they specify the following:įront Differential with a G2 fluid, which is a GL5 75W85 $59.49/. It's time to drain & fill the X5's Front & Rear Differential fluids. I hope that some of you gear heads can maybe explain to me the REAL reason for BMW's Front & Rear Differential GL5 viscosity fluid change.
