Does driving fast waste more gas?

Slow Down and Drive Conservatively

Speeding increases fuel consumption and decreases fuel economy as a result of tire rolling resistance and air resistance. While vehicles reach optimal fuel economy at different speeds, gas mileage usually decreases rapidly at speeds above 50 miles per hour (mph).

Does full tank petrol last longer?

Filling up a tank halfway compared to a full tank of fuel only reduces the weight by 2.5%. At this level it is likely to make very little difference on the vehicle fuel economy. We suggest if your drivers are regularly driving to advise them to fill the tank all the way to the top when they visit a petrol station.
