Hmm..cool... I am glad you have noticed the difference!

The only thing I haven't tried was the Rotella..and boy did I get fried by many, especially those of the 1500 crowd, for mentioning that you should use a 'wet clutch, motorcycle specific' oil!

I will additionally add that the oil's properties, at least from a 'feelable' aspect, doesn't change during it's service period unlike Castrol's 4t product that starts out great, but then after several thousand miles begins to exude a rougher feel/run.
Have fun man!!
