1. Lose weight
Get rid of heavy storage that you've left in your car. If your trunk is full of stuff, your car needs to burn more fuel to move.
2. Fuel up efficiently
Should you fill your tank full or half way?
Filling up your tank halfway does in fact reduce your car's weight, therefore you get more milage, because you need less energy to move.
Filling you tank to the full means that you save more time, by filling up less frequently, however a full tank is heavier and slows you down slightly, which could mean you need more gas in the long run.
Make sure you do not top up your tank between fills. It is a waste of money and bad for the environment. If you have a tank that is half full or three quarters full then you are forcing the extra fuel into the evaporative emissions system, where it overwhelms circuits that take the fuel from the tank to the vapors of the engine.
The best time to fill up is when you have a quarter tank. It's the most cost effective.
3. Don’t warm up your car for too long
Because we live in the UAE, we really don’t need to warm up our cars for longer than 30 seconds. Any more time, then you are wasting fuel.
4. Don’t always have your AC on maximum
It's impossible to suggest rolling down the window during the heat, but your AC shouldn't always be on full blast. Instead, increase the temperature, and lower the fan power.
5. Buy petrol early in the morning or later in the day
Because the weather is cooler earlier in the day, the petrol is therefore more dense and cooler. As temperatures rise, the density of the petrol is lower and you get less of it when you pump. So pump it early on, and it slightly expands in your tank as the day gets warmer.
6. Don’t brake too hard
Braking too much wastes petrol and wears your brake pads out faster. The best way to reduce the firmness of your breaking is to maintain a safe distance from the car in front of you, so that you don’t have to hit the brakes too hard.
7. Drive steady
As much as many of us speed when driving, if you’re low on petrol, slow down and drive steady. Don’t accelerate too quickly, because that wastes it.
8. Turn off the engine when you can
If you have the chance to switch your engine off, do it. Whether waiting for someone outside, or if you just need to pull over somewhere. Keeping your engine on will majorly waste petrol. The car will still stay cool for a short period of time
9. Close your windows on highways
You may think that switching off your AC and driving with the windows open will save gas, but an open window, on the highway specifically, increases resistance and costs you fuel in the long run, so keep your windows closed whenever possible. You want to make your vehicle as aerodynamic as possible.
10. Relax on the road rage
When your driving is more aggressive you are actually using more fuel. Aggressive driving causes people to accelerate rapidly, as well as braking hard. This uses more fuel than you think. So stay calm and save on fuel.
11. Drive Less
If it’s possible for you to take the metro, or public transportation, you might be saving more on the increasing cost of petrol. When not doing important drives like work, try to find one place where you can conveniently run all your errands, rather than drive around all over town. If you’re going out with friends, opt for a carpool or call a taxi.
12. Track your route
Start taking the routes with less traffic lights, and less turns. The more you stay on a straight line, the more fuel efficient you are. Always give yourself time, so you don't have to rush to your destination.
