bud was using RP MT oil in his b18c for a good year, tracked it a few times, drove hard all over the shop, various conditions, besides the hexy price, it did a good job

OEM only!!! (pretty much).

None of this motul / fully sick (not so) high performance stuff.

Depends on what the gearbox characteristics are. I know the Renault boxes I was used to as a young bloke only took single grade 80w oil as any multigrade stuffed them within a week. Why? Who knows.
Don't necessarily go OEM, just stick to the manufacturers recommended grades and if the shifts are not so good find out about higher performance oils then.
redline is great but a little costly. Lucas additives are good for gearboxes too as is Nulon G70.

[JasonGilholme]

80w is way too heavy for a honda box.

They're designed to be used with oil that has similar weights to engine oil.

If oem didn't suit your box , then there is an issue that OTHER fluids were masking with thicker or additives. Oem is actually the best stuff for any Honda gearbox , short of a full blown race car and it's long hard working stresses.

:thumbsup: i always used oem in my ITR gearbox

[Limbo]

i used OEM in my box and i tracked it twice without changing, still all good.

[shmivic]

OEM ftw.

i used redline once in an ITR lsd box and it blew after 20kms. Literally had an apple sized hole in the bottom and destroyed gear set. Nothing like a driveway covered in g/box oil for some fun.

[big tone]

a few ppl i hear use ATM in the itr box.... they say its a light oil with all the protective additives...

[cazz'shonda]

OEM would be the dearest way to go for gearbox oils I am sure. There'd have to be cheaper ways to buy it. Dealer prices for anything are usually +100% at the least.
I'd go with the CVTF for any CVT boxes though.

BTW, what do Hondas usually specify for manual transmissions?
Some euro's of the 90's were running actual engine oils in the boxes from factory. Made it so cheap to keep cars on the road as you'd only need one type of oil.:thumbsup:

Honda MTF is 75w80. That is a different rating (gear oil rating) to the one used for engine oil which is 10w-30. Notice that the engine oil rating has the "-". In fact, 75w80 is very close in viscosity to 10w-30.

Honda specifies Honda MTF which is a 75w80 transmission fluid.

That's probably because your gearbox was already worn out. If you don't want to use OEM, then Elf makes a 75w80 oil that you can use in Honda manual transmissions.

gearbox is fine BTW, i jus need sumthing that can handle VTEC 24/7 if yah no what im saying....

[EK1.6LCIV]

get ready to buy some syncros (my bet is on 3rd) if it gets beaten 24/7

Honda does recommend using their engine grade oil to use as a top up for a period of time til the proper fluid is obtained, it's be tried and tested

I've tested Honda MTF in my gearbox for 90 minutes of 4000 to 7000rpm in 15 minute non-stop intervals. Does that count? :)

being in the high lift point of your engines rev range has absolutely nothing to do with you gearbox, or in fact the oil used in it...

You could be in "vtec" for 150 years and it wouldnt affect your box or the oil in it...

the thing that affects your gearbox and you clutch is the driver... if you are giving it to your box all the time you will break it... i remember in my previous car i went through 3 boxes but the motor was perfect... its because of the way i used to shift gears....

Anyway, i always use OEM, having owned the car since new, the gearbox still feels new, i change the GB oil every 6 months

if you're baller, you can try NEO from http://www.gccorp.com.au. NEO gold is $88 for 5 litres

Huh? What???? What does engine oil have to do with transmission fluid?

And $88 for 5L is hardly baller. $100 for 4L is more baller. :p

[CRXDEL501]

dont mean to bring up an old thread, but what neo gold gearbox oil would be suited for dc2r?

would this one be the right one'?

[shmivic]

again for oem oil only.

have had serious dramas with a previous eg b16a/itr trans car of mine using non oem gbox oil.

gets real messy real fast!

[mocchi]

the statement of "OEM FTW" is not exaggerated. it is indeed for teh win.

[Phased]

*****IMPORTANT OIL INFORMATION******

First of all. These gearbox failures I hear from various users (if it was narrowed down to the oil, which is unlikely) I can almost bet vital parts of my anatomy to the fact they purchased the INCORRECT OIL TYPE and/or VISCOSITY... It has ABSOLUTELY NOTHING to do with Brand!!!! BE VERY CAREFUL do NOT purchase heavy weight or "shockproof" gear oils for Honda's. ie. Redline Shockproof/Royal Purple 75w90 GEAR OIL. Use a Oil that is specifically designed for Syncromesh Honda Transmissions and Helical LSD (Type R's etc.).

OEM Oil is not "FTW". Although in all honesty... If your using it and don't trash your car it will probebly ensure that your transmission will outlast you're car. As in most cases they are dumped, stolen, written off before a lot of these symptoms would come into effect.

Remember that producing oils that will prolong the life of a car when that company still manufacturers new cars... isn't exactly in their best interest, is it? All "conspiracies" aside they're not going to put money that could be spent on R&D that will actually make them money to preserving the life of their cars when they are more than 10 years old... are they?!?!

Secondly, did you know OEM oil changes around the world? Although the basic additive group, viscosity and API Grades remain... the oil base stock and manufacturing process changes. For example OEM Oil in various countries has been synthetic for quite a while. I know for a fact that Caltex Manufacturered FEO Honda Oil here in Australia (well I'm not sure about now but i know they did in 2007/2008). The oils use the same base stock as the very basic of Mineral oils... the Additive compilation MAY change but for the most part... it's your everyday mineral oil.

Back to Transmission oil specifically. I have used AMSOIL Synchromesh MTF Fluid in my old Accord Euro and now my Prelude... Shifts smoother particularly when cold and shifting stays consistent for longer drain intervals. This AMSOIL fluid is ACTUALLY designed to be a direct replacement for Acura(Honda) MTF 06. It's a FULLY SYNTHETIC (PAO, Group IV) Base-stock.

Regardless of Fluid Quality or Brand if you change it regularly you're on the right track, and most likely won't experience any problems; provided you treat your car with a little respect.

Also; aaronng if you are reading. Have you heard anything about this new FEO Synthetic now available at honda?! I'm sure it's probably going to be a group III :(

im drinking ultra light beer 0.5% alcohol. it taste like crap.
your post on the other hand is very informative and i like it.
i like how you take different perspective (crude oil bases).

We've tried Motul LSD Type 2 FF with great results on a couple of FN2s with crunchy gears as well as B18 g/boxes with gd results too..smoother gear change

nice and all - but why was the car crunchy in the first place ? Sounds like driver error/ stupidity rather than OEM oil choice initially. You are putting a bandaid fix on it if the gears are crunching !

FN2s have slightly crunchy (unsmooth) gear changes from factory since day 1 as discussed on the FN2 forums hence why some of the owners tried out with the Motul to see if it fixes it..and clearly it has.

As discussed is this a universal issue (recall) or just with some owners trying to race or grab second too quickly ? I've noticed my ep3 very occasionally touches second but its lazy effort in timing the shift/clutch release

ive had my box rebuilt about 6 months ago and im using penrite Manual gear 70. and it is the same rating as honda gear oil.. API GL-4. i track it and drag and im rough on the clutch.. ive not had a drama at all...
and its less than half the price..
