Fuel Saving Tips

Fill up when temperature is cooler

Fill up when temperature is cooler. Gas/Petrol expands a lot when it is hot, but the energy remains the same. According to one report, 20 US Gallons at 60F is the same as 19.6 US gallons at 90F--so that's 2% less fuel if you fill on a hot day. The pump volume/price remains the same! And the oil companies factor in temperature when selling to your local filling station. The same principle holds true for diesel, but it expands slightly less, rough guess about 1.7% in the same example
