I am reading thru this thread and does below fluids sounds correct?
BTW FCP-Euro recommends G2 Hypoid for Front and 75W-85 for rear outers. They don't have anything for rear middle when I select my 2016 X6M Front - 2 x 0.5L BMW G2 Hypoid Differential Fluid (500mL) - Genuine BMW 83222413511 Rear(Outer Chambers) - 3 x 0.5L BMW Final-Drive Gear Oil Carbon Mod SAE 75W-85 - BMW (83-12-0-445-832) Rear(Middle Chamber) - 2 x 0.5L SAF-XO Rear Axle Differential Fluid, SAE 75W-90 - BMW (07-51-2-293-972) Last edited by MBoss_F86; 10-17-2021 at 09:40 PM.. |

The centre section and the Front diff should be the same. Well according to RealOEM. Front and centre section should be running the newer version 83222365987. |

I saw that. Is there a publication from BMW or ZF to says that? There is probably a fine line line between compatible and recommended, or what came from the factory.
I'm sure we could fill these with 5w30 and they would turn over, at least once. I did see that PN# under the main general fluid overview, but under the actual rear diff service for a F85, F86 it only has the 987, and 832 oils. ISTA grabs; Last edited by Chilled; 10-18-2021 at 09:10 AM.. |

To make things even more confusing....
Looking at the F90 forums, and I see the following: BMW G2 for Front Diff. BMW G4 for Middle Rear Diff. https://f90.bimmerpost.com/forums/at...1&d=1532400356 I think the newer diffs are getting recommended the new stuff vs our older vehicles having the older fluid. I'll be sticking with what came in the car for both Front and Middle Rear diff: 07512293972 and use the Porsche stuff for the rear outers from FCPEuro as I plan on using the warranty multiple times long term. The "G" stuff is double the price of the existing fluids, I don't understand what makes it so special. Last edited by nishfish87; 10-18-2021 at 11:00 AM.. |

The Slightly Concerning part is that I cant see anything on realOEM or bimmercat for F95,F96. ista did return on a 2020 F95, and it looks like there is only the one drain port/fill plug. So it should be the one oil type. Im guessing |

To make things even more (or less) confusing I contacted SilverSpringBMW who own getbmwparts and they said this! Same fluid in front & rear diffs
- SAF-XO Rear Axle Differential Fluid, SAE 75W-90 - BMW (07-51-2-293-972) Hi, thank you for your interest - according to the provided VIN, the same fluid is used in both front and rear differentials on your X6M: 07-51-2-293-972 $21.36/liter BMW doesn’t show any different fluids per chamber in the parts catalog for rear from what I can tell. PS: BMW of Buffalo who is a M certified dealer also said same fluid for Front and all Rear!

There is some discussion over in the F87, with BMW putting into one guys rear diff. Didn't read the full thread but it looks like he not happy and is planning on replacing it. https://f87.bimmerpost.com/forums/sh...1722843&page=4 Also for that part #, on ECS they have this "This is the same synthetic differential oil used by BMW dealerships to service "open" or non LSD differentials. " That is not for a F85/F86 diff. Mine is a 2017, and for the centre section, and front diff "83222365987" is the correct oil according to TIS, ISTA, RealOEM. *EDIT* The oil could be the newer one for the F95/F96 hence why its not in RealOEM, but that would mean its not what these came with from the factory.

Three different M certified BMW dealers told me 07-51-2-293-972 is the fluid used in front and back. When I specifically asked them about chambers on rear they said this is only part # they could find in their parts catalog for my vehicle which is 2016 F86. What are the chances all three dealers gave me wrong info?
At this point I would trust BMW dealer over ECS or FCPEuro |

I think BMWs official stance on the outer clutch packs is "Do Not Service". It was brought up somewhere earlier in the thread, based on the guides from ISTA. I am just curious as to why RealOEM or TIS doesn't come back with any info on this OiL PN#. To play devils advocate, the 2x different types. Does it really matter for these rear diffs? As in they state that if the diff is over 45°, they will mix. What happens if you are driving aggressively swerving from side to side. Since the chambers are not sealed, would that mean there is a chance for them to mix? *EDIT*, just foudnthis thread with that oil PN#. https://www.e90post.com/forums/showthread.php?t=1442048 One of the guys claim that this one is the final drive oil, branded for the BMW Motorbike line. 972 Superweeds the "Final-drive gear oil SAF-XO - 33117695240" hat goes into the centre section, not the outer packs. The 240 is superseded by 987. In short, NFI. found the post Last edited by Chilled; 10-19-2021 at 10:50 PM.. |

I was told filling capacity for rear is 2.12L, so I assume they are changing all 3 chambers. Not sure why ISTA says outers are Not servicable. Since BMW recommended same oil for 3 chambers mixing while side to side drive shouldn't be problem?
Getbmwparts advisor - "BMW shows a filling quantity of 2.12L for the rear differential but they do not list a quantity for the front unit. We'd recommend consulting your vehicle owner's manual for that information" Also I read BMW shutdown Newtis since they don't have latest info. |

But i've got a newer version of ISTA at home, will check. But from memory it still treated the each chamber separately, with a DO NOT MIX stance. For my change, i am going to go based on the ISTA/RealOEM info with the 832 Carbon Mod for the packs and 987 for the center section. Unless someone can link us a bulleting that says we should roll the 972(75W90) into all. |

Thank you for the info. I will sent this to BMW SA ask him why they are telling me something different. Can you please tell what does your 4.31.16 version of ISTA recommends for front diff?

Interestingly enough its the "Hypoid Axle Oil G2", and I cant find oem vendor to say that this fits a F85/F86. I'm still learning ista, so I maybe missing some bits. Interestingly enough the F90 M5, uses the G2 aswell.
But RealOEM and everyone else says the "BMW synthetic OSP" (987). So im less than happy about my front diff oil choice. More research needed. Last edited by Chilled; 10-20-2021 at 08:18 AM.. |
