Abstract
An engine control module determining an alcohol compensated fuel consumption value includes an alcohol percent module that determines an alcohol percent in fuel and a fuel mass module that determines a mass of the fuel. The engine control module also includes a fuel volume module that calculates a volume of the fuel based on the mass of the fuel, a density of the fuel, and the alcohol percent.
