'18 440i xDrive 100k Service - Are my selections correct?
I'm looking to do a large service at 100k next month. This includes fluids for the front and rear differential, transfer case, transmission, coolant, and spark plugs. I've attached everything I'm buying with a few questions, primarily if I'm missing anything or purchasing anything objectively wrong. I have everything for the brake fluid as well. That is everything but the time to get around to doing it...

The front and rear differentials officially take different oil. Personally I do things by the book and bought the expensive BMW Hypoid oil for my rear differential.

Those two bottles are $125 rather than $40. I don't kind spending more for what is objectively better but in this case I'm unsure if it's that or simply confidence of buying the one with the roundel on it.
It's like the shell fluid I have on that list. As I understand it is identical to the BMW branded, but a third of the cost on account of the label. |

If I had to do it again, I'd get this: https://www.blauparts.com/ravenol-ge...8YcXe2Js0ZoC3U You only need about 850mL to fill the rear diff, so one bottle will do you. Here's what my rear diff looked like at 45k mi: Last edited by AspektUSA; 06-15-2023 at 09:30 AM.. |

They're like German Motul, or Liqui Moly's main competitor apart from ROWE.
It's cheap for what you get, and the bottle design is good as it has an integral filling spout. Using the 200mL syringe I have made the job just a little more tedious. However, you do need one in any case to suck out the old fluid. The FCP Euro diff tool worked great to get to the bottom of the casing. |

That list looks good, however I do agree with just spending the money for OEM fluid, it’s not a service you do all the time. I went OEM with the exception of using Liquimoly Top Tec 1800 for ATF
