What oil should I use?
Any good quality oil should work for normal use. 10w30 is fine. If you typically run the bike on the highway at full speed, 20w50 will offer better protection. If you run in the winter, 5w20 might be useful, but do not leave it in during the summer, it'll be too thin to provide good protection. If your bike's rings and valve guides are worn, a heavier oil may be better for you.
