Gearbox Oil About

[3beejay3]

I mix a 50/50 blend of Dexron 6 ATF and 10-40 motorcyle synthetic oil. I only do it this way because I used to have 4 stroke bikes and had a couple cases of 4t oil sitting around. This way I can use it up. I also keep Dexron 6 on hand for my truck.
I'll still mix a good 4t bike oil or similar and ATF once my stock of 10-40 has run out.

I put 900 ml in and change it every 20 hrs.

Honestly, these bikes are tanks and you could probably run just about anything in them without issue.....

I thank you for all the answers. But I've got a problem. I've been in the city only has Castrol dealer. I can get that transmission oil castrol.
Which one should I use? for EC 250 Racing 2T (2012)

1- Castrol Power 1 Racing 4T 5w-40 1Lt
2- Castrol Power 1 Racing 4T 10w-50 1Lt

I'm waiting for your help. Thanks all.

If Castrol is your choice, you can also use their MTX oil which is made for gearboxes like ours. I have used it some times and it works just fine.

Of those two, I'd use the 5-40.

over the years and the last few bikes, i have tried all sorts of different oils and atf... some are better for the chirpy clutch, most dont make much difference.
i pretty much use whatever reasonable quality oil is on sale at the time, and have never had clutch or gearbox issues... i like penrite products, but im australia.... as said before these things are basically the massy fergison of the bike world....
regular oil changes is the secret i believe.....

OK so I'm bringing this up. Hate oil threads. Anyway I have had a couple of cases of Bel-Ray 10W-40 Mineral Oil. I haven't been real happy with it in the Gassers. However I can't argue with free. But it's all used up.

I'm 99% sure I'm going to switch to Rotella 5W-40, T6. Full synthetic. Just double checking myself that with that. That's pretty much what all our machines will switch to.

Any issues?

I'm using 0W-40 Rotella T6 and it works OK. I had 5W-40 T6 before and can't tell any difference.

I doubt any oil will get rid of the typical clutch drag on a wet clutch. The only time I get clutch noise is if I'm in a gear too high for the conditions.

Merhaba,

900-1000ml of ATF type F is what I use.
