10w30 motor oil

stevenDAtegra

Yeah, 10W30 is what honda originally recommended until they came out with their own manual transmission fluid. They say you can use both but it's all preference.

Here are some others you can look up

GM Syncromesh
GM Syncromesh Friction Modified(What I use)
Redline MTF
Pennzoil Syncromesh(same as the cheaper version of GM Syncromesh)

666GSRGT35

use honda manual transmission oil or redline lighweight shockproof.

MFactory

Don't use the Redline Lightweight Shockproof, it is still too thick. Infact, don't use anything that says Gear Oil and/or has a weight rating.

In order of personal preference:

- Torco RTF (Not required unless you are putting down big power, or constant high-rpm shifting)
- Torco MTF
- GM/Pennzoil Synchromesh
- Honda MTF

A lot of people use the Redline MTL successfully, but some have had bad experiences.

Mista Bone

I've rebuilt quite a few trannys that used Redline MTL, so stay away.

10w30 or Pennzoil Synchromesh, good for 300 whp or SCCA ITA racing. Beyond that I wanna try the Torco.

I do have a 425 whp powered Y8 OBX tranny living on Synchromesh......yeah a rarity.

666GSRGT35

I use redline lightweight shocproof for mor than a year into a 360 whp daily drive car and I have sell them to many people and have no problem?

MFactory

A basic analogy would be: Oil is your transmissions blood supply and needs to flow smoothly. Clog it up with cholesterol (i.e thick gear oil), and it will have a heart attack. Not enough Iron (i.e shock additives), and it will get anaemic/weak.

Can you use the thick gear oil? yes, of course, just like how you can eat McDonalds fries everyday. Doesn't mean it's doing you any good

Honda Bull

I think I'll be testing this or Motul out next. I should pick some up before two weeks when I hit the track. The Amsoil I have in there now is beat and just put back in to get my car running.

MFactory

aha, I knew I missed out someone. We have a few guys over the pond running the Amsoil Synchromesh on their weekend warriors without problem, so there's another one to add to my list

Blown90hatcH

Been running Redline MTL without any issues for years.

666GSRGT35

hum...ok if your a guy of mfactory you know tranny more than me.I have ordered a case of torco rtf yesterday. thanks man

Mista Bone

we need to talk then............rebuilt MANY Honda trannys after Redline MTF

MFactory

[politically correct mode]
Redline MTL i.e Lubricant
[/politically correct mode]

we know what you mean though :p

Blown90hatcH

yeah...MTL. doh

Anyone know the Viscocity Index / Viscocity of the Torco RTF or Torco MTF?

*WHEW

i was reading through and no one said anything about Amsoil, i just filled my jdm gsr with oem lsd up with some Amsoil Synchromesh.. the only thing that had me iffy was the label on the bottle said it's a 5w30, and honda recommends 10w30 oils.. shouldn't be a problem, should it?

shifty35

the 5W / 10W part is the "winter" = W rating. Thus, it only indicates the viscosity when cold. Both are a 30 weight oil at operating temperature.

MFactory

Actually, just looking through the Redline website and they actually have a super lightweight shockproof fluid which, looking at their specs on paper, is very low viscosity. This may work good as well, although I don't know anyone who has used it.

Their lightweight shockproof, on paper, is actually similar to the Torco RTF. However, after having tried both fluids in our transmission, what they put on paper is certainly not what we experienced

kulo

im going to be getting this stuff instead of honda MTF

anyone running this stuff?

Ok, I guess I will be grabbing 2 quarts of 10W-30 GTX to run in the stock STD trans. Is there any advantage to synthetic oil in the gearbox like a Syntec or would conventional work well.

The plan is to pick up a d16a1 or ZC to swap into my 91 STD as well as an Si or DX transmission, so I don't plan to run anything major until then, but the real question is: Does synthetic matter in the gearbox or would GTX suffice?

tuckin' flush

I just put 10w40 Syntec in mine. They say that the 10w40 is better for a lot of highway driving. It's working great so far! I've only had the car for 3 days, though. Haha

Mista Bone

synthetic is too slippery, won't let the synchros bite as hard.

Like running crappy brake pads.....which is all a synchro is.

MFactory

Unless you need the GL5/GL6 protection (i.e shock additives), run a fluid based on mineral stock.

i dont know how much experience you have with the lightweight shockproof ****, but it works absolutely fine.




oem syncroed straightcut box.

**** works great

MFactory

Yup, on paper it looked good, hence why we tried it. Wasn't so good after we tried it though
