How frequently do you have to change your oil using this oil?
Harmrod from Martinsville, In on
Harmrod because everybody has different driving habits and climate I hate to give a time or mileage that you should change your oil . I would say to follow the manufactures suggestion on oil changes. I don't know if you knew this or not but you can even blend a quart or two of this Lucas Oil into your regular oil for easier starting and extended oil life.
