Just wondered what brand of oil you use in your duke. I know that Ducati are in bed with Shell but I found that, on recommendation from Opie Oils in Cornwall, Motul is much cheaper. I got 4L of the shell advance ultra 4 equivalent for £25 instead of £36 for shell. Changed the filter for a K&N one too. What do you use? Pete
Looks like I might be trying motul 300v and I run k&n oil filters too. Currently running shell advance but only because I got a bottle when I bought the bike. It was running thicker motul stuff after its last service and it ran really nice at high rpm but I tickle it mostly so swapped it back to the usual shell. Right, just checked and 50 notes for 300v? Might not at that price.
The Motul I have is the 5100 15w50. Cost £25 for 4 litres from Opie oils. Can fault them. Just googled the oil and the average is £9.99 for a litre. Pete
