Hi, again...
I think we had a little miscommunication. My concern, EVEN IF Ducati says 7,500 miles....is the 7,500 miles on the OCI. Shell Advance or not....
I AGREE that I sure would not drop $12 a quart for "motorcycle oil". I did that for a while in my Interceptor then went to a 15W-40 HDEO. Seems to be every bit as good and at a fraction of the price and I can change it more often without feeling like I am pouring dollars down the drain.
Frankly, if that were my bike, I would run Rotella T 15W-40 in it. Those premium 15W-40 HDEOs' are VERY tough oils. Those oils are intended to stand up in diesel engines with 20 to 1 compression and operate for LONG OCI's....they are not wimpy oils!
If you live in a hot place or the engine will see a lot of heat, you could run a 20W-50 in the summer. If you live in a place with more moderate temps, the I highly suspect a premium HDEO in 15W-40 would be perfect for that motor....and I would change it every 3,000 miles like clock work.
....The above is just my opinion..... based on many years of being around all kinds of engines, gas, diesel and racing, and reading a lot of well thought out and documented threads on here.....
Good luck with you Duc.
