How often do you change your oil 3,000 miles? Or do you let it go 7,000. On my Road King I will let it go as much as 4,000 with synthetics, but never more than that. On the old Shovel Head I don’t have a tachometer so I just look at the oil to see if I need to change it. But I don’t use synthetics in it. Should I?
