TAF-X; more than one type?

Recommended Posts

I saw some TAF-X on Ebay, and since I used my last drops last year thought it prudent to order a bit more for stock.

However In think I've boobed a bit, as it sounds like the wrong spec (GL4), it also has a different colour cap (red instead of the green). What have I bought? Is it any use or should it go back?

This was the last bottle I had;

I recently spoke to a Castrol tech guy here as I wanted to know what they were saying was equivalent.

I have since purchased Castrol Syntrax Universal Plus 75W/90. Yet to put it int though. Should happen in the next week when I get to work on the car.

Yep - Syntrax is the way to go for us Aussies. There's no other options here.  Easy enough job.

That is correct. There are even several Syntrans versions, so :

Castrol Syntrans Transaxle 75W90.

Lotus tested this and found it to be used as Taf-X went out of market.

Kind regards,

Jacques.

And according to Castrol themselves, it should be the Universal Plus version as it is the only one that has a GL5 rating. I think when Lotus did their testing, the Universal Plus was not around.

No, it's fine.

It's the original oil recommended for the transaxle by Lotus. The one I posted above is the Lotus-recommended replacement.

I would ring Castrol technical Mark and see what they say.

Thanks all. Turns out there is only one TAF X formulation after all, I was confused by the seller's VW ratings. From Castrol technical advice;

Castrol TAF-X was only in 1 formulation with API GL4+ and VW 501.50 specification (G50/G51).

More than 5 years ago this product was renamed to Castrol Syntrans Transaxle 75W-90. So, maybe it is worth to check the age of these bottles because we normally advise the shelf life of approx. 5 years.


I wasn't aware oil degraded particularly in storage, maybe the time is right to switch to Syntrans after all.

I mentioned to the tech guru that Lotus had not tested Syntrans in the UN1 and couldn't comment on its suitability, and this was the response;

 

It is still the TAF-X formulation. No need for testing imo

It is not the same formulation. There's a thread somewhere and the key difference is the Syntrans Transaxle 75W-90 has slightly worse high temperature performance than the TAF-X.

But does the net effect of oil degradation (as alluded by the tech guru) offset this? The newest TAF-X is going to be 10 years old by now.
