Ah, yes, yet another oil thread! For those newbies, oil, air cleaners, and tire threads run rampant about twice a year on motorcycle forums.
Here's the deal on oil, check out the owners manual first. That will tell you, at least, what won't hurt your engine. Use at least that level of oil, mineral, semi-synthetic, or synthetic. Any decent brand name will do the job for you and your motor.
However, use MOTORCYCLE oils. Modern motor car oils will kill your bearings and clutches. Synthetic motorcycle oils will not! I use Mobil 1 V-Twin synthetic in my bikes. Not a problem in thousands of miles because of oil.
For old timers, use what you believe in, even Shell Rotella diesel or airplane oil. It's not going to hurt your engine either. Dino oil isn't mentioned in the owners manual. I wouldn't use it for a variety of reasons unless you are very oil knowledgable. Experimenting down with oils ain't worth it. Good Oil costs about $20 every 3600 miles. Pretty cheap insurance.
