If I remember right I believe Ducati changed the ring design somewhere in 2013 model year. However I would be more concerned if it wasn't using oil. I know its not how we think but all engines should use some oil or lubrication is being sacrificed. As long as it is not too much all is good.
Mine is a 2013 try with about 2400 miles. Service done at about 800 and site window was full when I picked it up. Now showing about 1/2 in the window. It sounds like you run yours a lot like I run mine. I cruse in the 4K range but live in the mountains and once in the turns I am between 5 and 10K.
That's right.
They did indeed change the piston ring design at the end of, or near the end of the 2012 model run.
I think all 2013 models have the updated rings
As an update.
I have always used, and continue to use a 20w-50 grade full synthetic oil in my bike since the first service.
After the break-in period, my bike consumed about 200 ml of oil in 6000 kms.
After I switched the EBC to "off", the oil consumption has increased to some where between 600 ml - 800 ml/6000 kms.
I mostly put it down to 2 main factors which are worth while considering.
Firstly, the throttle plate is being closed more rapidly now that I'm riding with EBC switched "off", than it was with the EBC previously set at "level 3".
This has the side effect of increasing the duration and severity of negative cylinder pressure when in a closed/closing throttle condition.
Secondly, I am also riding the bike more aggressively.
This is due to the new found smoothness in the bike, by using my preferred latest engine and EBC settings in combination with the latest update.
