Hello all,
surprisingly enough, I was enable to find an updated answer to a simple question: what oil should I use for my all synchro Jaguar series 1 gearbox?
In some old posts I found references to oils that are NLA, hence my question today.
Thank you for your insights.

Thank you Steve, and sorry for being so inefficient at searching in the previous posts.
I'll order Redline MT90 as it is advised by Andrew.

I'll tell you my observations... when I drive the car, which is not tomorrow.
My next step is to start the engine, but I need oil in the gear box for that. Hence my question.
Thanks for your help
