Can mileage ever go down by using MAGIC plus?
There is no material or ingredient in MAGIC plus which can cause your mileage to decrease. Sometimes, vehicle users do not accurately calculate their baseline mileage. Driving patterns may change between fill-ups thus giving inaccurate results. In older vehicles, build up of varnishes and deposits in the jets or injectors may be so severe that when the catalyst dissolves the deposits, the fuel mixture being burn by the engine becomes too rich. In this instance, either the vehicle needs to be returned, or the fuel filters needs to be renewed.
