Disappointing fuel economy plus fuel tank size

you cannot accuratly work out fuel consumption by volume and a cheap fuel gauge supplied with the car, the only accurate way is by measuring the carbon in the exhaust and comparing it to the carbon in the fuel you use or by weight, the volume of fuel changes with temperature, you can draw it from the underground storage tank via the fuel pump and it may be at 2 or 3 degC, you put it in your fuel tank and at some point it reaches ambient temperature of between 10 and 20 degC which could equate to a 10% increase in volume, so you put 50l in , park it in the sun for a while and you have 55l , figures are approx guestimates but im sure you get the idea, the toyota prius was quoted at a rediculous mpg figure which was unachievable by normal driving, the us government changed the test criteria one year and it knocked 10mpg off of the manufacturers claimed mpg figure's for the car, if you cant afford to put fuel in your car then go buy one with a smaller engine
