A method for informing a dealer service center and a customer of a vehicle malfunction fueling in vehicles without flex-fuel property

摘要

An engine control system includes a fuel composition module, a comparison module, and a memory module. The fuel composition module determines a fuel composition and an amount of undesirable fuel in the fuel composition. The comparison module compares the amount of unwanted fuel with a misfueling threshold. The memory module records a misfueling event based on the comparison.
