Ok guys... today I went to my BMW Zentrum and asked about the diff fluids for the 1M. Here is what I found out. The factory fill oil for the diff is Castrol SAF-XJ. NOT the +FM, just the regular SAF-XJ oil. This oil should be changed at the first service 2,000 kms or 1,200 miles on M cars. This oil is spec'd for the M3 e90, e92, e93 and 1er M Coupe, aka e82 M Coupe, aka 1M.
You need three 500ml bottles to change the diff oil out. The diff holds 1.2L
Castrol SAF-XJ BMW part number: 83222282583 for one 500ml bottle. cost is 24 euros per bottle at my BMW Zentrum.
I also asked about the Castrol SAF-XJ+FM diff oil. My dealer had never heard of this +FM stuff... but it is a good part number. The price of +FM is 30 euros per 500ml bottle. But it is interesting that BMW AG does not say to use it. At least not in their latest service info to the dealers over here. |
I'm (still) a little confused. Isn't the part # referenced above (83222282583) correspond to the (+) FM diff fluid?
