Not to sound like a dick here, but if your going to give people information, at least be right when using it... again i dont want to sound like a dick. Regular motor oil that doesnt have friction modifiers works fine with these types of clutches. Lots of people will also use automatic transmission fluid type f, it is very cheap and you can get it at almost any auto parts store. Some of us have been running motor oil and atf fluid since before others were even born and havent burned a clutch out due to the oil. If you have the extra money to buy the expensive oil and it helps you sleep better at night knowing you run only the best then by all means spend the extra money but I have been using 10w-30 for a long time and have yet to find any ill effects on my clutch.
