Oh dear the great oil debate again!!
What oil you got? Everyone has there own favourites. I have even seen weasel Pee recommended on the Ducati index!!
Only use whatever the latest Ducati recommendation is myself, usually. This equates to whoever is sponsoring the Ducati Corse.
I can see the sense in going for a fully synthetic **/50.
Have a look at
www.shell.com loads of info. You can even win a 999!! (got to shift em somehow!!)
I would be wary of using a car oil in a bike, even tho' Mr Shazaam! does, purely for the reason that some additives that help the oil cope with the combined engine/transmission you get on bikes but not on cars MAY be missing. (Yes I know Old minis etc used to have 'em but are you really gonna use castrol GTX in yer bike??)
Whatever you go for I would change it every 12 months/3k miles whichever is the sooner, cheap insurance/
