I'm going to be swaping out my old civic motor to a new one but I'm not sure what kind of motor oil should I use for the tranny. The motor uses 5w-30 motor oil so should I use that kind of motor oil for the tranny too?

 

id use honda mtf (assuming its a manual)

but when our cars were new honda recomended 5w30 or 10w30.

 

Use only honda fluids FROM honda. Honda MTF for a manual, ATF for auto.

 

I used Royal Purple Synchromax in my swap.

 

syncromesh (GM, Pennzoil, etc) works well. It has a lot of zinc. Honda MTF is preferred.

 

Honda MTF/ATF is about $7/qt in my area, which is pennies more than the other listed names. I'd go with Honda personally, especially since its something that get changed once a year if lucky.

 

^^ same around here its about 7-8 dollars a qt... Honda is best!!.. same with oil filters as well!!

 

"What motor oil should I use for the tranny?"
lolz

 

Well, the fluid often recommended for Honda manual transmissions is called... motor oil. The fluid recommended by Honda (at least recently) is Honda MTF. 5W-30 works too though.

I personally use Amsoil Synchromesh. So far, so good. I don't worry about cost too much since it's not like I have to change it every month or anything.

 

Don't be an A.H.
The guy was asking a perfectly sensible question, some transmissions do use regular motor oil.
That's why he asked because he didn't know.

USE HONDA MTF OR ATF: RECOMENDED BY MOST.

 

This is from a 1996 Civic manual.

 

just dont use gear oil.

 

USE 10W-30 TILL U GET MTF OR IF ATUOMATIC ATF FROM HONDA
