Which oil to use

Hi
I’ve just bought my first Ducati, its a 1994 600SS, I have always liked the look of these.
My intention is to strip the bike down in the winter and get it to a mint condition.
But problem is took it for a maiden ride the other day and loved it so decided to take it out when wife and kids allowed.
So have ordereed an oil filter, air filter and some plug just to sweeten up over summer till strip down.
Can anyone tell what oil I should use and does adding an octane additive help with cold running?
Thanks
James
