    I use only Honda MTF. Its about $7/qt through the dealer. Sure you can use motor oil, spit, water... whatever else you like as well.

    I agree Brian honda mtf is the best but just expensive for us people that can't afford it I think Penzoil is the best for the cheaper route...

    Penzoil synchroshit? It's $2 or $3 cheaper than MTF...

    I've also used Brad Penn in my transmission, made it smoother but had trouble shifting at high (8500+) rpms

    High end oil brand(their motor oil is very well regarded).

    I agree the new MTF is pretty watery/thin; some people believe this is to help increase MPG figures in their newer cars. For me, it made my gears a little notchy. Avoid Royal Purple Synchromax(it's like the new Honda MTF with crappy cold performance).

    GM/Pennzoil Synchromesh with friction modifier has been good for me; Amsoil too, but it cost much more(I paid 12.50/qt). Also, in my older cars, regular (Exxon)10w30 seemed to work better than the new Honda MTF.

    Torco MTF is very good and if you can get it locally, it costs around $8.50/qt.

    I still have some bottles of the new Honda MTF that I may experiment with(mixing with 30-weight oil).

    They are high-end brands; many racers use them and they're usually stocked in shops, not stores.
