I read it on the bottle. I don't know why they don't put it in the heavier grades of oils. If you have a can of 5W-30, just turn it around and look for the star on the back, in it it will say "ENERGY CONSERVING" in all caps. It does not say that on 10W-40 or heavier. I'm not sure why, its just the way it is. You definately do not want to put an energy conserving oil in your clutch because it will cause it to wear out prematurely. Does that answer your question??Originally posted by JTT
I am curious Mike T, what makes oil weight related to the addition of a friction modifier? I am not flaming you, just wondered where that info came from, as I was not aware that oil weight had anything to do with these additives.
I can't say ALL blends of 10W-30 have friction modifiers in them. The way you can tell if you are buying the oil at an auto store is to check the back of the bottle and look for the star. It will say "ENERGY CONSERVING" in all caps in the star. Turn a bottle of 5W-30 and a bottle of 10W-40 around and check it out. NOW, the oil you can get at the bike dealer, I have no idea what that has in it. To tell you the truth I have never bought gear oil from the dealer for my MX bike. As for mixing ATF with a different oil. It is never good practice to mix different types of oils together. You can drain your tranny and fill up with the other, no problem, just don't mix them. See what works best in your gear box. Some fluids will make your gearbox shift better than others. If you were out in the desert and the only thing you had was half ATF and half 10W-40 to get you home, Mix away! But how often do you ride in the desert?? Anyway, don't mix em' One of the fancy chemical experts around here could probably give you a real reason why. :DOriginally posted by Luke Davey
Mike T, you say to stay away from oils with friction modifiers like 10w30. Does all 10w30 oils have friction modifiers in them, if not how can I tell what ones do and don't. My manual says to use 10w30 and im a bit sceptic about changing to ATF or a differnt weight oil. I am also curious as to wether you can mix ATF with gear oil ?
Any help appreciated.

IMHO, there are no oils avaiable that will actually "hurt" your engine. Any oil or fluid will allow an engine to die if not changed often.
