Transmission Oil

Recommended Posts

My Dad recently purchased a 2006 CRF250R for me. I had a 2004 before that and used Honda GN4 Oil in the transmission, and Honda HP4 with molybdenum additives in the engine. I have seen HP(high performance) Trans. Oil 80w/85w at my local Honda shop. I was just wondering if the HP Trans. Oil would be better for my transmission, but still give me the dependability. Any feedback is greatly appreciated.

The HP 80/85gear oil is all I've run in all my CRF's. Never had to replace a clutch and never had any problems. I've tried a few other oils and the HP seems to work the best.

The same here.

I've run both GN4 and the HP Trans Oil in the tranny on my '04X. I couldn't tell any difference with the HP, so switched back to GN4 so I only have to keep one kind of oil around. Honda recommends either one for the tranny, so I'll stick with GN4.
