ill see sup with it later. who sells them?kragen or pepboys? or do i need to go to those race shops where they sell high octane race gas?
my local pepboys doesn't sell it and we don't have kragen around these parts. I ended up going to an import/racer-supply store to get mine. You can also order it online. Check out these guys :

If you don't feel like changing fluids in the summer/winter, then you can try just running the mt-90 year round.

Oh my... that thread has quite a bit of mis-information...

1 - GM Synchromesh is not what you want... GM Synchromesh *WITH FRICTION MODIFIER* is the good stuff. The regular stuff isn't worth the trouble.
2 - Nothing wrong with Honda MTF, but Redline is better. Been running it in my tranny for about 2.5yrs.
3 - Synthetics are fine in the honda tranny. The problem is that the tranny requires a GL-4 based lubricant while most of the synthetics out there are GL-5 based. GL-5 based lubricants will eat your synchros. I searched high and low for a GL-4 based lubricant and at the time redline mtl/mt-90 were the only ones that I could find.

I've used both redline mtl and mt-90 in both winter and summer (below freezing winter & >100 deg summer) and I like mt-90 the best. The MTL was just too thin for my tastes.

With that all said, I've heard good things about Torco tranny fluid as well.

Honda recommends changing the tranny fluid every 30k. I change mine once a year, its cheap insurance. It is also incredibly easy. I can change my tranny fluid faster than I can change my oil.

Most of the people that I see that still use honda mtf use one of 2 arguments... 1 - it is good enough and/or 2 - its cheaper than redline. If people say #1 then you can't argue with that. If they say #2, then they are just being silly. In the case of a civic, we only need 1.9L of fluid. So the extra $10 spent at fluid change time on redline really shouldn't be a big deal. I've never seen anyone complain about using redline (or gm synchromesh w/friction modifier for that reason).

As for mixing mtf and redline... I'm not a chemist so I would never try. Ever seen what happens when you mix 2 different oils (of any type) ? They separate plain and simple and you may not even get the same protection that you would have if you just filled the tranny with the lesser oil/fluid. here is an example of what can happen when you add an additive :

Moral of the story here is don't be a backyard chemist and try to outsmart the folks who made the oil/fluid. Pretty safe to say that they know more than we do.
