RL MT-90 or Amsoil MTG?

I've been using the Amsoil MTG for the last year and a half. I drained the factory fill at 7500 and have been using it ever since. There was a noticeable difference in shifting almost immediately. I wouldn't hesitate using this lubricant again.
I tried both in my old car, a 1995 Nissan Maxima. I definitely preferred the Amsoil. Shift feel was about the same for both fluids when they were new and in warm weather, but the Amsoil was way better in the cold and retained its performance better as the miles piled on. I didn't notice any difference in noise, but that was a quiet transmission overall -- the only time it ever made noise was when it was failing.
Motoretro,
What's the app?
FYI - I have a Redline mix in my '06 Mazda transaxle - 2 qts MT90 and 1 qt MTL. It shifts great in all temps.

After using both, I feel the MTG is a tick better overall than the MT-90 for the same reasons mentioned above. I don't know how they compare exactly in price, but the MTG ain't cheap. They are both good products IMO.
I've used the MT-90 ... but I don't think you could go wrong with either fluid.
I've become a bit of a Red Line skeptic in the past couple of years so I'd probably pick the Amsoil. Plus, there are two Amsoil dealers that sponsor this site ... which would be enough of a consideration for me to tip a close call one way or the other.

just drained oem nissan 75w85 after a auto-rx clean and added mt90. feels pretty good, smoother than the oem fluid. i only went with the redline because i could get it in town.
I changed the transmission fluid at 5k and used Redline MT90. Much better than OEM. Mine is a 07 Tacoma V-6 6 speed. I will use MT90 again.

Amsoil MTG without a doubt.
Used them both in a Jetta. Both great in the heat, low temp nod to the MTG.
MT90 has a higher flash point,a lower pour point, & a lower Brookfield viscosity. What makes the MTG superior?

Good choice Motoretro! I`ve tried both,MT90 and MTG. The bad effect I had with MT90 is that once the transmission got good and hot,the shifter got really stiff and hard to move. With MTG,the hotter the transmission,the more "buttery smooth" the shifter feels. With MTG,I can literally speed shift through all the gears with my pinky finger,whereas with MT90,it would get so stiff that sometimes it`d get stuck in neutral instead of slipping into the next gear. Just my experience though.

Used both in my Toyotas and prefer the MT90.

It's not just about viscosity being consistent over temp. It's about friction characteristics, shear resistance, tolerance to contamination, and other such stuff.

I just put Redlines MTL in my Saab, much smoother and quieter so far. Also easier shifting when cold (we're coming into our winter)
I guess its safe to say that choosing either would be a fine choice.

MTL is not MT-90.
MTL is much thinner than MT-90 or the Amsoil product.
