You're now using a diesel specific oil in your Multi?
Is there a good reason or are you just a tight arse?
I read that you are on your 4th Ducati, did you run the diesel oil in those too?
How often are you changing it and why do you feel a high sulphur, high detergent oil would benifit your Multi?
What grade are you using? 5/40 , 10/30 , 10/40 ?
I know our dry clutch bikes sound like diesels...
Changed every 3K
5-40.
Mine's a wet clutch.

From the Calsci web site- "Three synthetics stand out from the rest: Mobil Delvac 1, Mobil-1 SUV and Shell Rotella T Synthetic. These are C certified industrial oils meant to be purchased in 55 gallon drums and used by companies which run a lot of diesel engines. The Commercial oils, as discussed above, have more expensive additive packages which are meant to prolong engine life and oil life, as opposed to being cheap to buy at Pep Boys and helping the car companies meet their CAFE requirements. These oils meet all the automobile requirements through SJ, and also have extra additives to help pick up gunk in the engine, to keep the oil from becoming acidic, and to maintain the oil's viscosity over a long time. In fact, the manufacturers talk about their oil's viscosity resistance to shear forces - exactly what a motorcycle needs."

"ROTELLA T does not contain friction modifiers that are added to many passenger-car-only-oils, and it does not comply with all requirements of ILSAC GF-1, GF-2 and GF-3 (the ILSAC oil specifications are often recommended by many gasoline passenger car engine manufacturers). That can be good for motorcycle/ATV use. Friction modifiers can upset wet clutch operation. And the ILSAC requirements limit phosphorus content. Diesel engines and other engines with highly loaded valve trains, as well as transmissions, need extra (compared to passenger car engines) extreme pressure wear protection, which is provided by an additive that contains phosphorus."
