Biodiesel data collection system

摘要

A vehicle biodiesel fuel diagnostic method may include determining a biodiesel fuel concentration of fuel added to a vehicle fuel tank during a fueling event at a fueling location and determining the fueling location. The biodiesel fuel concentration and fueling location may be transmitted to an information system where the concentration and location are stored in a database. The method may further include indicating an abnormal biodiesel fuel condition in the database when the biodiesel fuel concentration is outside of a predetermined range.
