When I had my UN1 rebuilt, I put in Morriss’s Lodexol SS 75W/90. I also have a note about API GLI-5 Universal, but can't remember what that's in relation to.
I can let you know where to get it if you e-mail me.
Gearbox has been fine ever since.

I know a lot of the Lotus guys use Redline MT90 instead of the recommended Castrol TAF-X. Also they avoid GL5 oils due to the destructive effect it has on the brass syncros over time.
 
I spoke to opie oils to see what they recomend,
they suggested redline lightweight shockproof oil, for racing transaxles
they are sending me 4 quarts for free as a trial which is very good of them.
Will let you know how I get on with it.
Any1 tried it b4?
