Hi all, thinking of changing the gearbox oil on my CR TR6.
Any thoughts on what grade to use?
Cheers
You will get as many different opinions as there are oils available.
Personally I use a specific multigrade gear-box oil (Penrite GB40) as do a number of others, but then again some people swear by those Nigel lists. Both types seem to be recommended by different gearbox re-builders so perhaps it isn't that critical.
