If You Must Drive, 10 Ways to Reduce Fuel Consumption
Even though we are aware that engines need fuel to run, that does not mean you can’t make some small changes to help you gain some fuel savings.
1. Keep tires pumped up
Tires that are underinflated have a higher rolling resistance on the road. This means that with every kilometer traveled, your tires generate more friction and rolling resistance, and hence, will increase fuel consumption. If all your tires are underinflated by 10 psi, this could reduce fuel efficiency by up to 10%.
2. Lose the weight in your boot
For those with a habit of keeping everything and anything in the boot, in addition to emergency spares, think twice when loading up next time. Every extra 50kg your car puts on increases fuel consumption by 2%.
3. Drive with AC
Driving with the windows down at speeds faster than 80km/h causes a lot of wind resistance, and costs you a lot more fuel. Contrary to what you may think, in this situation, it’s simply more fuel efficient to drive with the aircon on.
4. Don’t go too fast or too slow
When cruising down a highway, your engine works hard to overcome wind resistance. You’ll burn up to 15% more fuel at 100 km/h and 25% more at 110 km/h. That might tempt you to drive slow, but if you drive slower than 50 km/h, your engine would drop to a lower gear, thus using up more fuel. In conclusion, a steady 50 – 90 km/h on the highway is best to achieve optimal fuel economy.
5. Remain steady when accelerating
Avoid revving your accelerator to a high revolutions per minute (RPM). It’s better for fuel economy, as your engine uses less fuel when it is revolving slower, at a lower RPM.
6. Avoid braking aggressively
Slamming on the brakes increases fuel consumption as you need to accelerate again later. This is especially true if you follow too closely behind the vehicle in front of you. Not to mention, tailgating is dangerous and something to avoid.
7. Cruise in top gear
If you’re driving an automatic car, make use of cruise control to keep your speed constant. And if you’re driving a manual car, maintain a higher gear when appropriate. In each of these instances, your engines go through less revolutions per minute (RPM) and will reduce your fuel consumption.
8. Practice predictive driving
Look to the road ahead and plan your next move. Instead of slamming on the brakes to a complete stop, try slowing down as you approach the red light. Or when reaching the foot of a hill, start accelerating as you edge closer to it rather than when you approach it. Avoid hard accelerations when moving your car from a complete stop, or climbing a hill as it will increase fuel consumption.
9. Plan your rush hour route
Stop-start traffic puts a lot of pressure on your engine, thus burns more fuel. When possible, plan your commute to and from work carefully to help you avoid the worst of peak traffic.
10. Don’t stay idle for long
If you are waiting for something or someone for more than three minutes, turn off your engine. You may not be moving but as long as your engine is on, it’s burning precious fuel.
And a final word. Regular car servicing helps maintain your engine’s fuel efficiency. Engine parts work closely in tandem. If poorly maintained, sludge and corrosion will build-up between the parts making it difficult for the engine to work smoothly. This is also why engine oils are in the engine, combat sludge and improve fuel economy. (Courtesy of Mobil)
