TO MEASURE CONSUMPTION

The simplest method of arriving' at the- petrol consumption of a car is to fill the tank to the brim at a service station, having first carefully checked the! speedometer over a measured mile for accuracy. If the touring consumption only is wanted, the longer the run the hetter— up to 200 miles or more. Return to the same petrol pump from which" the supply was taken, see that the wheels occupy precisely the same position as before and then carefully measure the amount of petrol required to fill the tank again to the brim. Accurate information of what the car consumes around about town can be gained in the same way. First check the speedometer, then fill up and proceed about your business or pl'easure in the ordinary way, without giving thought to petrol saving or anythig else ahout the car, aiid when the tank is low return to the pump and accurately measure the amount required to refill. Most motorists will have their eyes op'ened if they adopt such a course; tests, as a rule, are made with a bias in favour of the car. The real test must be made under ordinary driving conditions — i.e., the best test is ordinary driving itself.
