So what brand and viscosity oils do you use?
Stick (or should I say lube) with a full synthetic
motorcycle oil. Auto oils have additives that adversely effect wet clutches. Even more of these additives are found in auto "high mileage" formulas.... avoid, avoid, avoid!
Full synthetics resist degrading due to high operating temperatures and resist shear much better then non-synthetics. Furthermore, Ducati recommends using a full-synthetic in the 1200.
Viscosity selection depends largely on the climactic conditions in which you regularly operate your cycles. What others use may not apply to your situation. A viscosity range chart is most always included in respective owners manuals.
Filtration IMO is equally as important as oil choice as all oils become contaminated. Recirculated contaminants are a source of accelerated internal engine wear. Choose a filter with a small micron filter. I personally attach a few rare-earth magnets to the external filter to subdue the most microscopic of ferrous material from recirculating through the Testestretta.
Also, the frequency of oil changes will get rid of contaminants. IOW, the day you change you oil is the cleanest/best it will
ever be. Accelerated oil change intervals are relatively inexpensive insurance for peak performance of any internal combustion engine.
I personally use Castrol Power RS Racing 4T. Superstition causes me to stay with the same oil for the length of my ownership. YMMV.
In closing, short term testing of oils mean little. I am waiting to hear the Marvel Mystery Oil report from the 1200 owner with 1,000,000 miles under tires without rebuild.:think:
