I don't live that far from an HD dealer but!! There is an Advanced right around the corner, Autozone not to much farther, and Every other auto parts store to think of that is closer than the dealer? So with that said what is a good brand of oil and filter? Should I go synthetic? The bike is an 09 12SS with about 4k miles and I don't race at all or ride really hard..... That much! What should I look for?
