Exactly! The reason it is "energy conserving" is because of the friction modifiers used to reduce friction. Great for metal parts, not good for wet clutches. A good synthetic is very beneficial in that it resists thermal and viscocity breakdown. Most have antishear additives and such to help with this. A good dino oil made for motorcycles (4T) is the next best thing.Just a little FYI for those that use car oil,
You need to understand that if the oil bottle says "Energy conserving" on it, that its not the best oil for your wet clutch. Energy conserving oils have special friction modifiers in them that help you get better milage in your car, they also make the wet clutches in motorcycles slip a bit. You may not notice it happening, but the few people that stopped using it and went to Non Energy conserving oils noticed a small difference. Non Energy conserving oils do much better in motorcycles who's engine oil circulates through the transmission.
Motul no longer produces the synthetic oil for Kawaski. If you have the old bottle that says "100% Synthitic" on the label with a red cap and black bottle that is Motul E tec 100. If you have the new stuff that says full synthetic in a grey bottle it is not produced by Motul. I beleive the new line of oils that were introduced about a year ago are blended by Citgo. If it is Motul it will say so on the back label in small letters on the bottom. The Motul stuff is good stuff. I used to use it in my 03 Z1000.Motul
