My dealer's service manager told me that they use a bulk 10W-40 non-synthetic oil for all oil changes. That's just one reason that I have never had the oil changed by a dealer, either auto or motorcycle. If you want it done right and with the proper oil and filter called for by the manufacturer, do it yourself or buy the components and take them to a trusted mechanic. My CB was delivered with the engine overfilled with oil which I siphoned off to the proper level at home. When I bought my ST1300 in '06, I noticed that it was overfilled with oil and had the dealer drain off the excess oil before I rode the bike home.
