Curious as to what type of gear oil everyone runs?

I am about to do a clutch change next weekend and figure I may as wel put in good fluid at the same time. This will be used for my street/weekend fun car

 

well, i use 80/90w gear oil, but for 99.9% of people out there, standard honda mtf will be fine for them.

I've tried a few including Honda MTF, GM Syncromesh, Redline HSP, and good old 10w30 which Honda reccomends. The only one I experienced problems with was the 10w30. The Honda MTF seems to break down faster than the others mentioned. I personally like the Redline HSP best.

You do realize that gear oil and motor oil viscosities are rated differently by the SAE, right?

An 80W-90 gear oil is (very roughly) equivalent to a 10W-40 motor oil.

Sometimes I am just an idiot. But aren't there additives in hypoid gear oil that Honda does not ask for in their LSD and transmissions?

Chris didn't mention whether he is using hypoid or non-hypoid oil. IIRC, he is running an ATS diff? I'll let him comment on why he uses what he does.

I personally prefer a little lighter 75W-80 gear oil like Redline's MTL. Right now I'm using the Synchromesh, which is really thin stuff.

you sure about that targa? i use ATS 80/90 (you were correct, as i have the ATS diff) and the stuff is MEGA thick compared to mtf or plain motor oil. takes me twice as long to refill the trans vs. using mtf.

It might be closer to a 20W-50 motor oil. It really depends on the oil and the conditions. You've got to be losing some power with that stuff.

You live in the Arctic anyway. I'm surprised oil flows at all up there

 

redline is what I was thinking about going with. Ive heard that OEM fluid is not good enough for hard driving, and the GM synchromesh is what everyone brags about, but I dont have access to it here. I have seen Mugen gear oil down at the honda dealer, anyone use that before?

bah, you heard incorrect. honda transmissions in general last forever, but in the hands of the average person on these boards, the lifespan is shortened dramatically. i have almost 200k on my 99 si with no trans issues using mtf, as well as there are numerous other people that have big mileage with no issues as well.
i love the threads of people having "the notorious third gear grind". it is hilarious. there are nothing wrong with honda's design, learn how to shift stupid....

hince the reason im asking. figured I would put the question here since its going to be used for gymkhana

 

I have a Cusco Diff and they reccomend Synchromesh(friction modified) with an lsd additive. I've also used honda mtf with a Jeep friction modifier. No problems with either one.

 

synchromesh here..
no problems so far.

honda mtf is a no brainer worry free option as well..
