[Dazbot99]

Hello all, what is the best diff and transmission oils to use in these w116's?

Mine is 280se 1977.

Thanks for any advice.

As per the service manual for the diff you need Hypoid Oil SAE 90.  Not sure on manual transmission, I am sure other learned members will chime in.
Here is the Benz spec sheet 235.0 for Gear Oils:

To my knowledge, manual transmission were to use Typa A Automatic transmission fluid. That's what the service manual says, but the only place I can find Type A ATF these days is at Exxnon service stations.

Fuchs Titan ATF 10 seems to be the one for manual trans.
