Good stuff, I had a chance today to test them out on my Y21, I got them for 7.8CAD at the amsoil dealer. It feels better than BG Synchroshift II IMHO, but I still have to try them on the track in the next few weeks.
I tried Redline MTL, Redline 10W30, Honda MTF, BG Synchroshift II before.
BG was the best out of the four, solved my 5th gear grind, but they are so overpriced, I got them at my local chrysler dealer for 21CAD/quart.
For those who want to use BG Synchroshift II or GM Synchromesh, this is an alternative product for half of the price.

 

So MTF has an actual weight like engine oil does? I never knew that...

 

Yes, and are like 75W90...I wonder what car use those.

 

I use Redline 75w90 in my CTR LSD equiped tranny.

 

I think 75W90 is gear oil weight, SAE means for motor oil? I think 5w30 motor oil is like 75w80 gear oil, can someone confirm this?

 

We sell this stuff at our shop, and it IS awesome in comparison to all the other fluids out there. Finally!
