Yeah,had the tank been full at Trinidad,the 24 miles over the mountain would have worked out at around 18 mpg with the additional 0.914 gallons.But it will require a return trip to the Shell station in Trinidad to figure the discrepancy.
This is why auto makers abandoned road testing in favor of wind tunnels,where they have total control over parameters.
