Daryl, I am not telling you to use extra "additives" in the oil. Mobil 1, like all oils have additives in the oil. Many bike oils have moly for example--a high pressure lubricant additive. Both Honda and several oil makers uses small amounts of moly in their products both for cars and bikes. The Mobil 1 product line has moly in their performance 15W-50 oil but not in their bike oils.
Daryl, adamant or not, every bike I have owned but with a few exceptions (Ducati) has had a wet clutch. I have been using Mobil 1 auto oil in them since 1979 I think. I have had several "fast" bikes and a number of UJM's (Universal Japanese Motorcycles) and a few Europeon makes. NONE of them have ever had a slipping clutch due to Mobil 1 auto oil. My current ride, a Suzuki SV650S, a real fun little bike, I wheelie and stoppie and run pretty hard. It runs Mobil 1 15W-50 despite the admonition from Suzuki to use only bike oils and bla bla bla. It has a V-twin engine with an 11,000 RPM redline and a wet clutch. It is not a super fast bike but trust me, it is plenty fast to get me in trouble. I used to race bikes, even for an "older" guy, when it is time to raise a little "hades" on two wheels I am fully capable, the point is, I ride hard and my bikes need a good oil--that oil is Mobil 1 15W-50 auto oil. The MX4T is great--it ought to be at more than twice the price.
Next time I do a burn out in the garage I will have to get my wife to snap a pic /forums/images/graemlins/shocked.gif. Love holding the bike back with the engine bouncing off the limiter and smoke rolling off the tire, yeah, I think I need the moly that Mobil PUTS in some of their oils /forums/images/graemlins/cool.gif.
Hey, go to the Ducati web site and then click on the Sport Classics. You see the yellow one---when those are available I am buying one /forums/images/graemlins/shocked.gif, it looks like the Ducatis I have owned in the past--they have a noisy dry clutch by the way. Check them out--way kooler than my current spiffy little ride. J
