Does this oil work

[Whitty21]

I went to a local honda/yamaha dealer to get tranny oil, yamalube4 specifically. All they had was HP TRANS. It is an 80W85W. I was reading the back and it said it had antii-wear and anti-slip additives, but it is the oil onda uses in their CR's and the trx 250r's. What do you think?

Should be fine. Anti-wear and anti-slip are not the same as "friction modifiers." Things like slick 50, teflon, etc. you want to avoid.

for tranny oil you want to get 75w or 80w. if there is 2 numbers i wouldn't use it. 75w or 80w is equal to 10w30 or 10w40 motor oil and that is what yamaha calls for. so 75w80 is significantly thicker

why would yamaha call for thicker oil then honda, trannys can't be much different, i will wait for more input before i do anything

sorry if i was unclear but if the 80w85 stuff you have is what honda calls for its honda that recommends thicker oil. yamaha recommends the 10w30

i understood what you said, just wondering if anyone new the difference in the two trannys, just curious

i run honda hp trans oil 80w/85w in my blaster. i've been running it since i got it a few years back and never had any problems out of it, but my clutch is going out now. its also the stock clutch from 1990 so it probably should have been gone a long time ago

two numbers don't mean its any thicker. Ive been running 80w90 gear oil with no problems. Typcially I run 80w bel-ray gear saver. 75w or 80w is much thicker than 10w30 or 10w40 motor oil as well, I know with my bike 10w40 is to thin and the clutch slips like nothing else, but 80w back in and its back in business.

Frankly, I use 10w-30 motor oil, no particular brand, although I like to buy synthetics. Yamaha recommends Yamalube 4 because it is their brand, but they don't say it must be their brand. Sure, there are alot of expensive brands out there, but when was the last time someone complained about their transmission gears and bearings wearing out? Keep oil in the transmission and change it occassionally, that's the key.

As for the 85w80w gear oil type designations, gear/trans oils are rated differently from motor oils. Here is a nice chart, you can see that 30w is roughly equivalent to 80 or 85 gear oil.

While it's true that gear oils have better extreme pressure additives, Blasters only have like 16-35 HP pushing some straight and helical cut gears. IT'S NOT AN EXTREME APPLICATION.

Honda's HP TRANS will work fine, Belray will work fine, AMSOIL will work fine, etc......If it says it is motorcycle transmission oil and you want to pay $10+ a quart, fine. The only real rule is try not to mix different oils 'cause sometimes they will react with each other and gum up (theoretically at least, I've never actually seen this happen).

If your clutch slips, it's worn out or not adjusted correctly.

i run the honda hp stuff because i can get it right here in marysville. the only other stuff i can get around here is amsoil, and i dont feel the need to pay more than ten dollars a quart for the stuff when i think the honda stuff might be like $6? everything else i have to either get on the internet, or its a half hour drive to iron pony. my clutch is probably slipping because i used the thing to pull branches out of the woods when me and a buddy were cutting up firewood to sell

LOL. Sounds toasty.

LOL. Sounds toasty.

yeah i know. it sounded like a good idea at the time lol

Thanks guys, i think i am going to go with the hp trans, thanks for the help and info for future knowledge. rep given to top helpers

i know this thread is old, but DO NOT use the hp trans oil at least for an extended period of time. my clutch lasted like a year on it, but i just put a new clutch in it and before i poured more of this stuff in the transmission, i read all the fine print and turns out it has anti friction additives in it. therefore your clutch will not perform as it should. my suggestion is to drain it and just use yamalube
