Fuel Saving Tips
When filling up with fuel and the fuel stops, leave it, don't click it till it's really full the pump isn't precise enough to measure the little bits of fuel going into your tank but the $ ticks actually think there's more than there is. I managed to fill a 10 L gas can with 20 L as an experiment and still had to pay for the 20 L even though it was impossible to hold 20L but that's what the pump read. You have been warned. Also, as your fuel tank heads toward empty, your car becomes lighter and so uses less fuel during acceleration, you might squeek an extra mpg or two below half a tank.
