I have been waiting since about 1989 which is the first year i had a Honda 250ES. We had an old Kawasaki dirt bike, i don't even remember model or such but it was on the farm since before i was born, and that ran whatever oil was handy to toss in there as well. I would guess there is more to the story than just the oil that causes the elusive clutch failure but who knows!
Regular maintenance is the key, drop the oil regularly, its only like 1.2 quarts per change. Buy a case of quart jugs and keep it changed often, your engine will love you for it and its cheap insurance. Whats the cost of a case of oil compared to an engine rebuild? Exactly...
And everyone so far is wrong on the size, the drain cap is a 24mm wrench, if you still have the factory tool kit then its the big spanner wrench that also removes the valve adjustment caps. A tip there... If you have the factory tool kit take the 24mm spanner and put the handle into the 17mm side of the t-wrench (the plug wrench) to extend the wrench handle and give you a bit more torque, like adding a cheater bar. If you don't have the factory tool kit buy a 24mm wrench at a local farm supply store or a good hardware store that sells them by the wrench so you don't have to buy a set. Its well worth having a wrench that size on hand.
