Sure you can.
Yes!
Use SAE 5w-30 weight oil.
SAE 20W-50 Synthetic Motorcycle Oil
Use SAE 5w30 full synthetic. 4.2 quarts with oil/filter change. Use any major brand of your choice, but I recommend Pennzoil Platinum Full Synthetic.
It can use either or but synthetic is the best for your engine well worth the 10 dollars more it is!!! f.y.i.10w 30 valvoline full synthetic is the best in my opinon
