My new to me 1993 MB 300SD kind of fell into my lap. I bought it for the engine and transmission but it’s growing on me. I decided to change the differential oil after a 300 mile trip where the car ran beautifully. The car has 291k miles on it.
This car has the anti-slip differential option. It was a $775 option in 1993. It has a hydraulically and computer controlled LSD that can adjust clutch lockup between 30-100% based upon conditions. No idea how well it works… no dummy lights come on for it though the dummy lights work.
I anticipated that it would be dirty. In reality the fluid came out decent in color and smell.
The fluid came out ok. The plugs were filthy though.
The drain plug had a heavy coating of sludge on it despite not being a magnetic plug. The fill plug also had a decent coating of black junk but nowhere near as thick.
I refilled with Walmart super tech conventional 80w-90 with lubeguard limited slip additive. I didn’t want to go expensive when I figure I’ll probably be draining this in a year or so to get out any other junk. Then I’ll probably go 75w-90 syn.
