What transmition oil should you use in a 1992 Honda Civic?

Answer 1

The specific gear oil properties ought to be in your owner's manual. Usually, filling with Honda MTF (manual Transmission Fluid) or ATF (automatic transmission fluid) is recommended. You may buy this from a Honda dealer.

Having said that, I use GM Synchromesh in my manual transmission.

Answeryou can also use 10w30 motor oil.

I disagree...the jury is out on that one, but the issue is that there are so many formulations of oil these days (synthetic, part synthetic, etc) and the additive packages are all over the map. Sure, the wrong fluid ain't gonna toast the tranny, but the synchronizers like to have just the right stuff. Go with Honda MTL and play it safe. In the 'olden days' most 10w30 oils were pretty similar, so that's what the mfrs would specify...not anymore.

Ditto for Honda ATF...they add a special additive pack and the cars really do shift better with that stuff in there. A generic Dexron III will work, but the car is gonna shift a little later and a little harder when it's cold.
