I know. Kind of a broad, if not dubious question. But I have noticed subtle differences between the few oils I've tried. The over square 90 degree twin in my Ducati can generate some vibration for sure, and can become rather buzzy at the higher end of the rpm range. Weirdly, the new gen "DVT" motor in my 2016 is buzzier than the Testastretta 11 degree motor my '13 had. I say weirdly because Ducati boasts the DVT to be "smoother" in all aspects.
The reason I'm seeking to find the oil that smooths out the vibes the most is on account of this business with my eye. The MD has restricted me off vibrational stuff like electric shaving razors, electric toothebrushes, and maintaining my crew cut haircut with a Wahl trimmer, etc. (Been going to a stylist and she is able to scissor cut it almost as short). Whether the avoidance of vibrations will be permanent I don't know, but it's enough to interest me in at least trying to get the engine to behave as smoothly as possible.
I can say with some certainty that the current oil in the sump (see sig) makes the engine vibrate more. This was even the case with the same 15W50 oil (Spectro) in my former '13 Ducati to the point I changed it out early and put in Silkolene 15W50 instead which did run smoother.
In the case of my '16, the dealer recommends the Spectro and put it in at the 600 miles first service. I'm not knocking the oil, it is after all a true blue PAO and Ester blend and I don't know why it makes the engine buzzier but it does.
I have to admit to being attracted to the marketing/label hype of the Shell Advance Ultra 15W50 which lays a claim to making the engine run smooth and with less vibration. Hence my previous post trying to locate same for retail purchase.
I'm just trying to get my head around *why* what amount to Group III oils like Shell Advance and Silkolene, make the engine seem smoother than what a PAO/Ester blend like Spectro does?
