I believe most dukes come out of the show room with Shell in, i must admit my old 748 used to be run on Putoline 10/40 which had covered over 60k before droping the crank/main bearing on a track in France, my new 1198 has always had shell in from day 1 so will stick with that.
Shell have had close links with Ducati for years during the WSB days so thats whats put in from the factory and I would say most of the dealers will be "encouraged" to use it. To be fair any semi or fully synthetic will suffice as long as the grade is correct (10W40) and the right amount and changed on a regular basis. Unless you either race or do lots of trackdays then semi is fine. Also dont use car oils as these are meant for slow rpms and the gearboxes are seperate so dont have the shear stabilisers that are needed in bike engines that share the gearbox oil.
That'll be the one The oil thread, a fave topic for any dickwad who knows next to nothing about engines, but can string together a few bits of bullshit about viscosities, shear strength, friction modifiers and other second hand shite he's dredged up from the internet Take it away boys
Ok Einstein, it's extremely complex, so hold on tight and see if you, the multinobbers and the other fashion victims who "bought into" the brand recently can follow this as an approach; Read The Manual Good luck
I believe Moto Rapido have stopped using shell now I wonder if I qualify for 'buying into the brand'?
It's not normally mate, but oil, tax discs, tyres and multi windscreens are generally considered faux pas by all but but the innocent of members, don't take it personal like
