Gearbox oil

[eviljim]

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?

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

I use Amsoil 0W40 and am happy with it.

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.

The same here. Works better than the Rotella for me.

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'm currently using the same fully synthetic 5w30 I put in my car, smooth as silk!

I've used the Amsoil 0w40 in my 200 and 250. With and w/o Rekluse.....no squeal, no chatter, shifts great.
