The actual fuel consumption model will look something like this: Gallons consumed per hour = k + p*X where “k” is the gallons per hour of gasoline consumed with no power load and “p” is the rate at which gasoline is consumed to generate X watts of power. The “k” factor is similar to idling your car at a stop light.
