Fuel Mileage Checking Oversights



Most filling station gas pumps underregister the gallons to avoid code
enforcement fines. Therefore calibrate the gas pump by pumping gas into a
known calibrated container. This error will falsely increase your
calculated mileage.

Most odometers are wrong. Calibrate that against road markers. An
overregistering odometer like mine will also false increase calculated
mileage.

Road surface conditions, water or snow on roadway, load in car, winds,
grades are variables which affect mileage.

Less critical is temperature and atmospheric pressure, and altitude.

Tire pressure is often overlooked.

The professional mileage contestants pump up their tires to about 60 psi
for optimum mileage. They don't care if the tires blow out. Its the
mileage that counts, dude.

Some of you guys out there think you're getting 35 mpg from your Imperial,
but you aren't because all of the above confuse the issue.
