I have found the Honda MTF specification...Need Aussie/Brit Help!
It has taken months, and a tip from a friend at Honda engineering but I found the Honda MTF spec. It is called MTF-7289. It is as I guessed a light gear oil of 75w/80w viscosity, equivalent to a 10w30 engine oil. We know it has about the same additives as engine oils but with more calcium, ostensibly to friction modify the oil to have more "bite" for better synchro function.

Problem is, it breaks down quickly, esp for those of use who drive the car hard.

Red Line MTL is a good alternative, at least from the numbers. There have been mized reports from the field. So that in a nutshell sums up what we already knew.
************************************************** **************
Honda MTF-7289 has a counterpart made by Caltex, which is a ChevronTexaco supplier in the Pacific Rim. that may include Australia.

Here is the link that gave me the "Eureka!".

I have not found any supplier here in the US that offers that product. It is MTF-94. So, if anyone knows where we can get it, that would be a real contribution to the S2000 scene. MTF-94 is made with base stocks that should provide vetter protection and longer life.

There is another possibility, a Castrol product made in the EU, called Castrol SMS-X. Again, I could not find a domestic source for this product.

I wonder if our Australian and British friends can look into this? It might be possible to ship a few cases over here for analysis and field trials.

Maybe if enough of us wrote to Texaco or Castrol, we could get some of this.

Why do they only send us their 2nd-tier products? Although, I am told that Autozone has some German Syntec - you have to look on the bottle and see if it says Made in Germany. That is supposed to be much better than the US product nearing the same name.

 

I did a quick search on google.co.uk for this. It seems that Rover sell this (Rover is a UK car company btw-make land rovers and the like)

type in mtf-94 on google.co.uk and read up to see if this is what you want

If you want I can give one of the garages a quick ring-if you are really interested I can ship some over

Can you explain why you are so interested in this stuff. If it sounds like we should all be using it then stick a post on the UK S2000 forum
