As you shop around to find a fuel-efficient vehicle, you'll notice different average mileage figures given for driving in the city and on a motorway.
Yet there are many other reasons why a car's mileage could vary. Fuel economy can fluctuate not only according to the car you drive, but also to how you drive it.
You might be driving a car that is supposed to achieve 50 mpg, but if you gun the accelerator and leave the engine idling, you won't get anywhere near such mileage in real life.
Here are a few tips to keep in mind to help you maximize your car's fuel economy, courtesy of the fuel-efficiency minded folks at Carsales. Don't forget that fuel efficiency leads up to big money savings at the gas pump.
1. Stick to the speed limit.
It's a surprisingly common misconception that if you can reduce the length of your trip by driving faster, you'll burn less fuel. In reality, you burn fuel at a more rapid pace when you exceed speeds of 65mph. Wind resistance increases at higher speeds, meaning your car has to work harder to keep up the pace. The most efficient speed you can travel is between 55 – 65mph, after which efficiency will rapidly decrease. Driving at a speed of 85mph would use 40% more fuel than if you drove at 70mph. When on the motorway, try using cruise control to maintain a safe and consistent speed.
2. Reduce your car's weight.
Another way to boost efficiency is by reducing your car's weight and drag. Remove extra roof racks if you're not using them, because these increase wind resistance. Try to eliminate extra weight from inside the car, as well. If you've been carrying around spare luggage or packages in the backseat or trunk, it's time to clear them out. You can save 1% on fuel for every 45kg/99lbs that you remove from the vehicle.
