engine oil?

[Orlando]

the last oil change I got at the dealer they put Mobil 4t fully synthetic oil in my Daytona 675. Does anyone know what weight should go with. I called the dealer and she said they put 10w-50 and that didnt sound right to me, maybe she made a mistake on the numbers. What do you guys suggest? I wanted to add some oil to my motor to bring the level up a little.

10W-40, 10W-50, or 15W-50 (if you can find it) are all OK.
