Which oil in ZF

[mazmonza]

Which oil do any members use in their ZF 5 speed gearbox ?

[Benz Dr.]

I use synthetic ATF in mine.

[Atazman]

Pennzoil ATF (GM and Mercon)

[mazmonza]

Does it have to be Dexron 2

[Benz Dr.]

Does it have to be Dexron 2

Not sure about that but it should be red.

Not sure about that but it should be red. 

Some ATFs are green....

[Benz Dr.]

Some ATFs are green....

Yes, and some are blue for hydrac transmissions but most modern ATF is red. Any ATF should work, but a ZF 5 speed is an extremely rare and valuable unit which really doesn't hold a lot of lubricant, so I use the best I can find which is a synthetic.

[mazmonza]

Are you willing to say which one?

[Benz Dr.]

Are you willing to say which one?

Sure. AMSOIL, Quaker State, Royal Purple, etc.  Most are expensive but you only need about two liters so it's not a big thing. I also use synthetic lubes in the entire car. Engine, transmission, rear axle, power steering, grease. Lubes are pretty cheap compared to engine rebuilds or any other part of your car.

Thank you for that
