Title: Castrol TAF-X in the USA
Message: Here is the response to the inquiry I sent to Castrol USA about where to get Castrol TAF-X in the USA: "Castrol TAF-X 75W-90 GL-4 gear oil is made in the U.K. and sold only in Europe. However, the equivalent in the U.S. is Syntorq LT. Having said that, Syntorq LT SAE 75W-85, API GL -4 is a premium high performance, synthetic gear lubricant for synchronized manual transmissions. The all new "clean slate" approach enables Syntorq LT to provide consistent performance and durability under the most severe operating conditions due to its unique polymer free formula. It has been designed primarily as a problem solving gear lubricant for manual transmissions to provide reduced gearshift effort at low temperatures. Syntorq LT is available through General Motors (Part #12346190) and Chrysler (Part #4637579) dealerships. Please contact your local dealership."

That article comes up short in the critical issue - what kind of EP additives are being used? It comes down to the sulfur compounds added as part of the EP add pack: if they are "active" sulfurs, they can damage yellow metals. There are sulfur compounds that will not, unless a loty of water gets in the fluid and when heatede, forms sulfuric acid.
It is best to stick to what the mfr recommends. In the case of the S2000, that is no GL-5 fluids, which include GMS, GMSFM, and the MT-series of Red Lines.
I once spoke to an "expert" at a major oil company who did not know what an active sulfur compound was - yikes!

I agree that article talks about some people trying to use a GL-5 in the NV4500 tranny and are aparently doing so with success due to shorter change intervals. However the GM synthetic MTF is a GL-4 fluid and yellow metal safe. Am I missing something?
