In brief - yes, Ducati and Shell have a marketing alliance to promote sales, so there is a difference in marketing at least. I looked long enough to realize Shell was hiding the info on both of these blends, Shell Advance Ultra 4T 15W-50 and Shell Advance Ducati 15W-50, so I am just guessing but I think there is no difference except price. Shell just has press releases. Every other oil I've searched for had standard product content data sheets easily available for comparison.
In sum, both of these oils are for fuel injected, O2 sensors, wet clutches and catalytic converters of which I have none, so I don't care. And perhaps a factory fill oil during the break-in period is only for that purpose? No marketing whiz is going to suggest to switch to a more appropriate oil after the initial break-in,...
