If I had a way to capture and store the fresh RL I just put in, I would...and proceed to try other products for a back-to-back comparison.

I've drained it into a gallon plastic water jug and re-used it before. Pretty easy to do.

I thought about this because the motorcraft stuff in my current 6 speed only has 250 miles on it. I'm just not sure if it's a good idea to recycle fluid. It's also recycling the crap that it flushed out fo the trans.

I'm going to try the MTG. It will cost me under $30 for new fluid.

If it's low mileage and you're cheap, I don't see the harm in reusing it. Just store it in well-sealed plastic milk/water jugs. If/when you reuse the fluid, use a long piece of tubing from the tranny up into the engine bay, with a funnel on top. Pour the fluid into the funnel, but strain it using some sort of screen, like your wife's nice metal collander with the fine mesh. That should strain out anything big enough to worry about that wasn't already stuck to your magnetic drain plug when you first drained it.

Switched to straight Amsoil MTG last year in every car and have no complaints. Best shifting and seems to last more hours than Redline as well.

Amsoil 5-90 GL-5 for the Torsens
OS Giken 80W-250 for the OS Giken diffs

I'm tempted to send my MTG with about 18-hours on it out to Blackstone for an analysis.

I am using Torco RGO 85/140 gear oil. It has been a really solid for me. It is thick, but for me it acts like a suspension for my gears..

So is the general consensus that Amsoil MTG is better than Redline, regardless of 5spd or 6spd?

Appears that MTG is just as good/if not better than the motorcraft synthetic. It also costs half as much. I paid $25 total for two quarts of MTG

Your synchronizers don't appreciate that oil. However, I don't think any trans you run will experience synchro failure prior to gear failure.

I have Amsoil MTG in my S2k and I have 2 quarts waiting to go into the Miata. Good stuff.

That is my opinion having tried both.

I've used both (MT-90 and MTG), I like the MTG better as well.

Street cars
We like to use something lighter to shorten time for things to warm up and start working smoothly on a daily driver, 70-80 MTL with no additives unless the trans is tired in which case we'll add 2 oz. of 1052358[/QUOTE]


By "tired" do you mean the synchros are weak? - My Miata is fine but my Ranger's 3rd gear synchro is really lazy. Think it would help?

I like the MTG better than the motorcraft. I can't really put my finger on why, but it just feels a little better. I think it is thicker. I really didn't think I was going to notice a difference.

While you're at it, replace the shifter bushing too. Mine went from being quite notchy to being very smooth after I changed the bushing and topped off the turret.

Buy the little kit and replace ALL the bushings... it's not expensive and everything wears in there.

This is what I replaced on my '97:

Might as well order one of these too, it's probably bad after 14yrs..
