As long as the oil isnt Energy Conserving you can use it but it will shear down quicker.
From what I have read online some people put as a good rule of thumb:
Auto oils (M1 15/50)-1500 miles
Diesel oils (rotella 15/40,mobil delvac)-2000-2500 miles
Syn "motorcycle specific oil" (amsoil, maxima)-3000-5000
all these are dependent on the riding conditions, riding habits
