I have and will always use Shell Advance Ultra 4.
Its what Ducati stipulate *must* be used in all their engines.
These are high revving, desmodronic big twins. The ones I flog .. hard .. are air cooled wet multi plate clutch systems.
I have seen a 50k engine stripped and the insides were spotless with very little precipitable wear on key bearings and components.
The oil cools so efficiently compared to multi that I have never, even under 100mph solid for an hour (motorway) never got the oil temp above 50% of its range.
Modern synthetic oils are outstanding.
They are also, if you want the proper stuff, expensive.
This expense is entirely justified if you want a bike that runs longer, further, cooler and requires less attention.
I will be using it in my Savage when it arrives.
Altho I am not sure if its suitable for this kind of engine tbh. They are not exactly 'high peformance' bikes.
I will flog the tits off the Savage tho. So maybe, will have a chat with a few wrenches and see what the verdict is.
Also got to remember this bike is a 20 year old design. Might not like modern fully synth oils as much?
Here's a little of their blubage:
