Oil for g/box and rear drive.

Hi all
Is anyone using 75/90 synthetic in their gearbox/ rear drive without any issues as I’m using it in the g/box with o/drive and diff in my 1970 TR6.:thinking:

Hi Roy,
For years I have been using Castrol Transmax, limited slip,fully synthetic LL75-140 in the gearbox and drive box with no problems or leaks👍
In the engine, fully synthetic 10/60, no problems what so ever, currently got Mannol 10/60 bmw m sport in there as it was on offer.
Bikes,
1000s, 30yrs (20/50 in use before10/60 was available)
Centauro, 20yrs
Cali ev, 1yr and counting,
Cheers Phil :beers:

Hi Phil
Thanks for response its for my 79 spada,wasn’t sure whether the newer oils might cause a problem but all seems ok in my old classic car.
Cheers
Roy
