I know the rules say you can not run automotive oils in a wet clutch because of the friction modifiers. However, I have encountered a growing number of people who use some form of 10w30 or 0w30 in 600cc and 1,000cc sport bikes and even ATVs.
Is the whole notion that automotive oils cause clutch slippage real? You read stories about how somebody walked to close to their ATV or motorcycle with a bottle of non JASO-MA oil and the mere presence of the oil in the same garage caused the clutch to slip. Then you read posts where somebody has been running non JASO-MA oil(s) for tens of thousands of miles with no issues.
I can buy and run SRT 15w40 and ST 15w40 all day for $2 to $3 and know it will work for as long as I own the ATV. However, I like to experiment, simply because I can.
I have a wet clutch ATV and a willingness to experiment for the fun of doing it. If it does indeed take the clutch out, whoopie. That is easily remedied. Besides, Honda allows the use of 5w30 and 10w30 in my ATV. The year round recommendation is 10w30 in my air cooled blast furnace.
Opinions? Factual data?
