Is Belray Gear Saver Hypoid Gear Oil the same as Transmission Oil?
I went to a shop to buy some Belray Transmission Oil 80w and they were out. But they had some Gear Saver Hypoid Gear Oil 85w-90. They recommended as a substitute, but when I read more closely the words "Not recommended for wet clutches" on the bottle at home I got a little confused.
By the way, my bike is 74 Kawi H2.

I have not put fluid in yet because I am waiting for my S3 kickstand so my vent will stop siphoning fluid out.
I just want to know if I need to return this stuff.

Thanks,
Jack

I would say no to it. Regular car hypoid oil works great.

return it & get the 80W trans oil

I hust put the 10/30 in My KH500. Then i read on the tips it can do harm and to use the straight 80 w ger oil. Does anyone one know hat harm I ill be doing ?

You have used four stroke motorcycle engine oil presumably so its ok for a wet clutch.It may have a shorter effective life due to there being more shear than its intended use (higher volume of oil in most 4 strokes). As for the difference in numbers the following is pinched off wikipedia.
"API viscosity ratings for gear oils are not directly comparable with those for motor oil, and they are thinner than the figures suggest. For example, many modern gearboxes use a 75W90 gear oil, which is actually of equivalent viscosity to a 10W40 motor oil. Multigrade gear oils are becoming more common; while gear oil does not reach the temperatures of motor oil, it does warm up appreciably as the car is driven, due mostly to shear friction (with a small amount of heat conduction through the bellhousing from the engine block)."
