Performing the rear differential service on the 1992 400E. This is a non-ASR car. ASR cars will have a different fluid capacity. The oil specification for this is 235 which is straight 90W. 85w-90 should be ok.
@patriksernc I hadn't checked the differential fluid since buying the car, so I didn't know the condition of it. I'm glad the previous owner kept up on it
I have done this, and heed the advice from The Friendly Neighborhood Technician, this stuff stinks and you don't want it anywhere on yourself. Nasty nasty smell...
