So what is the correct oil to use in your gear box

So many people using auto oils(10w40) and other using motorcycle gear box oil(bel-ray gear saver) would auto trans fluid be a good choice

Think about what goes inside your auto's trans.

Gear Oil versus Motor Oil 10W-40

Q: Tech Dude,
My owners manual recommends 10W-40 motor oil for the gear box in my 1997 CR 125 but your Gear Saver is 80W. Isn?t that too thick?

A: I?m glad I?m not the only one who reads my owners manual! You are very observant, Grasshopper, although you must learn that there are two types of viscosity ratings. SAE 10W-40 refers to motor oil viscosities and SAE 80W AGMA refers to gear oil viscosities. By perusing my viscosity sliding rule chart a 80W gear oil translates into a 40W (10W-40 or 20W-40) motor oil. So you are right on by using Bel-Ray Gear Saver Motorcycle Transmission Oil 80W in your gear box. Say goodbye to ?Mr. Slippy the Clutch?. This exclusive formula will hold up to the nasty shredding effects of those tranny gears and keep your clutch action consistent even under the most nervous clutch finger.

Does automotive gear lube have a different weight scale than bike gear lube??? 75w90 automotive gear lube seems way thicker than 85w bike gear lube. It's only a difference of 5, but seems massive. I can't imagine 75w90 auto gear lube is the same viscosity as 10w40. It's obviously much, much heavier. What the heck is going on???

Has anyone tried automotive gear lubes in their k5 tranny??? Like 75w90??? or 75w140??? They have them in full synthetic about $6/quart for the 75w90 and $12/quart for the 75w140.

I use 10/40 Castrol in my trials bike,but It doesnt work as well as the Bel-Ray gear oil I run in the KX's.
