Original BMW G1 Hypoid Axle Oil (Differential Fluid), 500 ml, for BMW 128i, 135i, 2 Series, 4 Series Gran Coupe, and i3 (2008–2025)

Original BMW G1 Hypoid Axle Oil is BMW's own gear oil for the differential in the 128i, 135i, 2 Series, 4 Series Gran Coupe, and i3. Hypoid gears mesh on offset axes, and that geometry puts heavy sliding load on the gear teeth, so an axle drive runs on a dedicated gear oil instead of engine oil. BMW has produced G1 under this part number since November 2011. The oil is made in Germany, comes in 500 ml containers, and BMW records its weight at 424 g (0.9 lb).

Original BMW Parts carry a 24-month parts warranty.

This number replaces the earlier 83-22-2-239-982. BMW marks the change as exchangeable retrospectively, so the current G1 can go into any car built to take the older number. BMW uses the same G1 across several chassis generations in this range: the E82 and E88 Cabrio 1 Series, the F22 and F23 2 Series, the F36 4 Series Gran Coupe, and the I01 i3. An owner with both a 135i and an M240i, for example, can service both differentials from the same stock of fluid.

Common Questions

Is this the same gear oil a BMW dealer uses?
Yes. G1 is the gear oil BMW dealers use to service cars with open, non-locking rear differentials.

Does G1 have a shelf life?
It does. BMW gives this oil a limited storage life and directs you to check the expiry date on the parts label before use.
