What oil should I use in my gear box?
Do I need to buy specialist expensive stuff or can I get away with a a car oil product?
 
oil

I've used ATF for the past few years. So far so good .I like the way the clutch feels/works with the ATF

You'll get almost as many responses as riders.
I use Rotella with 20% ATF. But I have a Rekluse and that combo has given me the best results on 5 bikes.

I did the same last change, and I'm getting some squak out of the clutch now if I abuse it. Does not drag or chatter, just makes some strange noises. Think I'll switch back and not use the ATF next change. Mine is the stock clutch, no Rekluse though.
 
I've tried motul transoil, motul transoil expert, gro synth, castrol mtx, motul 7100, castrol ATF, silkolene synth gear oil, delo 400, bp farm oil and belray gear saver in my 2011 and 13 300s.

For me castrol mtx has the least squawk and longest good feel at the lever and easiest to find neutral. It's also well priced in Australia. Mobil took castrol (bp) to court and won over what they were calling synthetic, mtx is now labelled semi synthetic.

All IMHO, and oils are different place to place. Hope tat gives some sort of insight.
 
trans oil

I've used Castrol full synth. 5w40, worked good for me. But I only use it because it's what I had available at my shop = free. Otherwise I would try an inexpensive 5w40 motor oil, or in the past I have used the Honda oils 2 stroke gear lube with good results.

You should be changing your gearbox every 2 rides at most- at least that's what I do, so I feel no need to spend a lot on oil, just keep it fresh
 
I have always used put online gp10 gear oil, it works fine when it's warm. Bloody hard work when it's cold. Finding neutrel may as well turn it off and select with your hand.

Tonight I've picked up some ATF, never used it before, but I don't have any gp10 in.

How much does everyone put in? I always put 1ltr in, but I'm been told it should be 800ml?
 
I've run Rotella 15W-40 in my '99 for well over 1000 hours of hard rocky-mountain abuse (hour long hill climbs kind of thing). Transmission internals looked spotless and the bearings all felt great last week when I had it all apart. The clutch grabs a bit more when its cold, but otherwise it works flawlessly.

I've tried Motul 300V, 7100, 5100, motorex . The conclusion is the same as in my former pumpkin, Motul 5100 10/40 is my choice as it not only smothers the gear change but also reduces the squawk to almost zero. It was the only oil that prevented missing shifting from 2nd to 1st on the katoom and therefore bailing me out on some nasty up hills :D . With the GG I found it to reduce the squawk to almost zero after the 2nd oil change of using 5100.
 
ten four on the diesel oil

I run 10-30 & 15-40 diesel oil in everything with out catalytic converters. Street bike, dirt bike, quad, mini bikes, lawn mowers, classic car and diesel trucks. I've been doing this for over 13yrs with great success.
 
I made the switch to Shell Rotella T last year. Much less expensive on the pocket book and works great. I have been buying the 18.9 liter pales on sale for $3.00 a liter.
 
All our deisel oils in oz seemed to have moved to the "ultra" standard with more moly, delo and rimula ( rotella) have gone to the new standard, bp farm oil is non ultra but wasn't real good in the gasser, works great in 4ts though.
 
Lol, I was hoping someone would pick up on that question :) I've been putting 800ml in since being told that was the recommended amount, but never had it validated
