Castrol synthetic TAF-X in a 5-sped 'box

PostPost by: Si_130/5 » Wed Aug 03, 2005 11:12 am

Hi,
On the recommendation of a friend who raced an old Esprit I've just put Castrol synthetic TAF-X manual transmission oil in my +2 5-speed 'box. It feels thinner than what came out and says API GL4/5, SAE 75W-90 on the bottle.
Is it suiltable for the +2 5-speed gearbox or have I made a mistake?
Grateful for any advice,
Simon

Well here's the answer for anyone who fancies synthetic oil in their 5-speed.
The Castrol oil turns out to be an appropriate replacement for the hypoid light EP80 gear oil specified for the 'box. Castrol UK say the sulphur content is not high enough to cause oxidation to the brass and copper elements.
So, improved low temp gear selection and transmission noise levels minimised with no downside - I've noticed a difference since changing it.

Good Luck,
Simon
