i have always been a proponent of honda MTF, but with this new build, which i actually did myself, and it wasnt hard, should i compliment it with redline or syncromesh or the old standby honda MTF? and if so please give oppinions on specific weights and reasoning.

 

I'd run the Honda MTF. I'm on a freshly rebuilt tranny myself (also self built) and I don't think there's any reason to spend the money on the FM if you're not having grinding problems. The way I had it explained to me was that the FM was just a thicker fluid, but I don't know how truthful that is.

 

thanks ricey. i was just feeling around, honda MTF has never let me down, but i am always looking for oppinions.

 

I have heard good things about the Redline tranny fluids. I believe there are 2 different wieghts so I the thickness of the oil is a concern for you then you can choose which fits your driving conditions/style.

Actually I have heard good things about all of them that you mentioned, if I had to choose one I would most likely try the Redline, but I would say its a toss up.


Ok I just looked it up, heres the 2 Redline MTF oils....

MT-90
Popular in Nissan, Toyota and Mazda manual transmissions and transaxles as well as other selected applications, this is a 75W90 GL-4 Gear Oil that’s slightly heavier than MTL. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting.

MTL
This 70W80 GL-4 Gear Oil (SAE 5W30/10W30 engine oil viscosity) is designed for use in manual transmissions and transaxles. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting. Popular in many BMW transmissions and in most Honda and Acura transaxle applications.

So one is thicker than the other if that is a concern.

 

I work at a shop that sells Royal Purplue. At first I didn't think any thing other than it was another syn oil. I was wrong. There was an independant tester that was testing products to show off his additive to improve oiling. Well the test was of a weighted bearing. put 1lb on the arm and it acts like 100lb on the breaing. On with the story the regualer napa oil took 2 plates the Red lin took three and Royal puprle took all 6 plates that he had. THe test was freaking out and he never seen an oil test so well. WITH THAT SAID i put the 10-30 in my tranny and it shifted smoother and it was quiter over all.

Royal Purple the only oil i use (after motro break in)

 

what about GM?
i know there was a big discussion about this fluid some time ago. i hear it is very good.

 

i did see somethinglike that too, but it was for pro-long, was thinking of royal purple too.
