Any GL4 EP80/90 was the factory recommendation so I guess not.

Have you tried a search on this forum - you will find many opinions to consider.

+1. Asking for opinions on the the right oil for a TR6 gearbox opens a can of worms. Personally I use good quality GL4 oil in my GB with A type OD, a garage put GL5 oil in by mistake once and the  friction modifiers stopped the synchro cones from working- it took two flushes with GL4 to restore normality.

As stated above it must be a GL4 spec   EP80/90 originally specified. 

The Penrite GB40 works very well in the 'A' type GB/OD

 

Avoid  25/50 engine oil as it may have high detergent level and cause frothing.

The Morris Golden Film AG90 is a GL1 spec so doesn't really fit the bill

I use the Dynolite gearbox oil, similar to the Penrite stuff.
