Assuming a water-cooled motorcycle and a dry clutch (or a separate transmission reservoir, like Harleys), I have no argument with the article. However, air-cooled engines run much hotter than water-cooled ones and require much higher heat and shear-resistance. So I would make sure to use a heavy duty or extreme service 20w-50 car oil (preferably synthetic) if you go this route with a Harley, Ural or similar machine. But also, remember that the RX3 uses a wet clutch. And as others have said, the friction modifiers in car oil can make a wet clutch slip. Over the long term they can soak into the clutch plates and damage them permanently. Maybe some clutch plates would resist longer ... and maybe some car oils would have less of an effect ... but I wouldn't take the chance. If I had an oil leak in the middle of nowhere and couldn't find motorcycle oil, you bet I'd fill it with car oil and hope for the best. Then I'd change it for JASO-MA as soon as I got where I was going.

I have Spud's favorite 15w/40 in my RX3 right now for break-in but prefer to run a full synthetic after break-in in all my bikes. I want to run a 20W/50 because that's what the neck tag on the RX3 specifically calls for. Like I stated in my last post, I've never had any real issues with clutches or anything running car oils in my bikes in the past....though the new oils have changed quite a bit.

As usual, I agree completely with FastDoc. The additives in the oil will usually fail before the oil itself. Therefore, changing the oil frequently is the most important factor.
