Method of informing dealer service operation and customer of vehicle misfueling in non-flex fuel vehicles

摘要

An engine control system comprises a fuel composition module, a comparison module, and a memory module. The fuel composition module determines a fuel composition and an amount of undesired fuel in the fuel composition. The comparison module compares the amount of undesired fuel to a misfueling threshold. The memory module records a misfueling event based on the comparison.
