Unlimited Oil Changes for 1 year: drain and dispose of old oil, replace with fully synthetic AMSOIL (most take 10W40), replace o-ring *does not include cost of oil filter (if needed) and cannot be used if less than 300 miles (or 1 yr) has passed since last change. Perfect for those commuters that tack on the miles. If you are putting on 2k+ miles a season you will save big $$$ with this package.
