Use the motorcycle version, and the correct one at that!

If you think I'm kidding, check out the Mobil 1 website yourself. It's all there.[/QUOTE]<span id='postcolor'>
That's all mostly fluff by the oil companies. Of course they want you to believe that not spending $8/quart will 'destroy' your clutch and engine. Mobil 1 works just as well as MXT4 at half the price. While it is true that the motorcycle-specific brands have more zinc, less friction modifiers, etc., they don't tell you the actual difference in concentrations. It isn't much in many cases.
You can blindly believe the oil companies or you can believe actual analysis and testing... it's your money. Do a search, I posted several links on tests a while ago, I'm just too tired to find them right now.
