7 tips to save fuel and drive efficiently

Cars consume less and less. Today's diesel vehicles offer consumption figures that were unthinkable a few years ago, not to mention petrol. downsizing engines, increasingly smaller, with fewer cylinders - few brands do not have 3-cylinder engines in their range - aided by supercharging and advanced management systems combustion, save fuel consumption while complying with emissions regulations.

But we don't always stick to the official figures. By applying a series of tricks to our driving, it is relatively easy to achieve savings. We can even achieve lower fuel consumption figures than advertised by the brands themselves! In this article, we'll give you 7 easy-to-apply tips for saving fuel.

How to save on fuel consumption?

1. Plan your trip well

A well-planned trip will get you to your destination in the quickest, easiest, and safest way, while saving fuel. Extending an hour's journey by just ten minutes can lead to an increase in petrol or diesel consumption of up to 14%.

2. Check your tire pressure

The tires should be inflated to the pressure indicated by the manufacturer and according to the weather conditions (in very cold weather, the tire needs a little more pressure). Driving with tires that are 0.5 bar lower than the correct pressure increases fuel consumption by 2% in urban areas and 4% in interurban areas.

Also remember that when traveling with your car heavily laden, you should also increase the tire pressure. Their level is usually indicated on the fuel cap or on the driver's door. If not, gas stations usually have a chart showing vehicle pressures by make and model. If your tires are underinflated, rolling resistance will be higher and your vehicle will consume more fuel. A practical solution is to have a portable compressor (air pump) in your vehicle.

3. Leave the essentials in the trunk

Before you hit the road, especially if you're going on a trip, you need to streamline the volume and load distribution. It's not just a question of space: driving with 100 kilos of excess weight on board increases the fuel consumption of a mid-size car by up to 6%.

If you use your car on a daily basis, we advise you to take stock of everything you keep in the trunk and take home what you don't need. Don't use the trunk of your car as a storage room. It's a simple and convenient way to spend less on gas and save a few dollars at the end of the month. Also remember that it is dangerous to travel with cargo in the passenger compartment, especially if it is not placed correctly.

4.Starting and starting the vehicle

Start your car's engine without pressing the accelerator: on gasoline engines, you can start driving immediately after starting; on diesel engines, wait a few seconds before starting to drive

Only use first gear for starting. Pass the second after about 2 seconds or 6 meters. Start driving slowly (20 km/h for 5 seconds to save up to 11% fuel) and avoid sudden accelerations.

5. Keep your speed constant

Keep your speed as even as possible, aim for fluidity when riding, and avoid braking, accelerating, and changing gears unnecessarily. To decelerate, take your foot off the accelerator pedal and, if the situation allows it, before pressing the brake pedal, you can let the engine brake act first. If you must brake, do so gently and downshift as late as possible, paying particular attention to inclines.

At speeds above approximately 20 km/h with a single gear engaged, if you do not press not on the accelerator, the fuel consumption is practically nil. At idle, the car consumes between 0.5 and 0.7 liters per hour.

6. Don't let the engine idle

During prolonged stops, it is advisable to switch off the engine, because, as we explained in the previous point, an idling engine consumes fuel.

7. Air conditioning or open windows: which consumes less fuel?

Use the air conditioning when necessary, otherwise the car will consume a little more fuel, especially at low speeds. To keep the air fresh in the passenger compartment, a compressor is activated. This is a device that is attached to the engine and is primarily responsible for keeping you cool in the summer. The fact that the compressor depends on the engine means that the latter has to work harder when the air conditioning is on. Your car will therefore consume more fuel.

On the highway, it is better to use the air conditioning than to open the windows of the car; in the latter case, apart from being a safety risk at high speeds, their opening directly affects the aerodynamics of the vehicle. The wind gets inside the cabin and air resistance is increased. This is how fuel consumption increases.

Especially in hot weather, it's better to keep the windows down in town (if it's safe to do so) than to run the air conditioning. On the road, the situation is reversed: it is better to travel with the windows closed and the air conditioning on.

By applying efficient driving techniques, you can save up to 15% fuel. Here are a few:

Use engine brake

If you ease off the accelerator when you realize you need to brake, you almost shut off the fuel supply, reducing your fuel consumption by up to 2%.

Always drive with a sufficient safety distance (it is forbidden to queue behind a truck to avoid wind resistance and thus save some fuel) and keep a wide field of vision that allows you to see two or three vehicles in front you.

Move in a long gear without too many engine revolutions

Optimize gear changes as much as possible Drive as long as possible in the highest gear and at low engine speeds (in town, use 4th or 5th gear as much as possible, while respecting speed limits). speed).

In theory, the torque of a diesel car suggests changing gears between 1500 and 2500 rpm. For gasoline cars, the optimum moment is between 2000 and 2500 rpm. If your car is not equipped with a tachometer, the engine sound can be used as a reference.

Enjoy the descents

Use downhill to save on fuel consumption. Take advantage of the inertia to get ahead of the gear change by circulating at low revs.

When climbing, delay the downshift as much as possible, by slightly increasing the pressure on the accelerator, but never fully.
In addition to saving petrol or diesel, efficient driving has other advantages: better driving comfort, as it avoids sudden braking and acceleration, and increased safety thanks to safer driving. anticipatory that respects safety distances in order to have more time to react.

When does your car use more fuel?

When buying a car, one of the interesting technical data is that of fuel consumption. There are three modes: consumption in town, on the road and mixed. Typically, driving around town will drain your tank the fastest. In fact, driving is erratic with continual braking and acceleration, which does not contribute to the aforementioned efficient driving.

On the other hand, if you drive on the highway, consumption is lower, precisely because you maintain constant pressure on the accelerator and less stress on the brakes. However, the faster you go, the higher the fuel consumption, as the engine has to fight against the resistance of the wind. Therefore, besides the fact that it is not legal to drive over 130 km/h, it is not advisable to exceed this speed if you do not want to see the fuel tank needle drop quickly. Finally, with the mixed consumption, you will obtain figures that are between those obtained in the city and on the road, since it is the result of the average of the two.

    Merci pour les conseils (rappel pour moi) et j’en profite. J’ai fait un trajet aller/retour dans le var (nord/sud) soit 2200 km avec mercédes c220d en parfait état, contrôlée, pneus neufs. J’ai eu mauvais temps, pluie dans les deux sens, voire brouillard ! j’ai donc roulé feux allumés sur 2000 km, radio, mais vitesse constante bloquée à 129 sur autoroute sans à coup, j’adoptais déjà vos recommandations mais alors que j’avais déjà fait ce trajet plusieurs fois avec une moyenne de 5,7 litres, là j’ai explosé. Est-ce vraiment dû aux conditions ? ma voiture n’a que 125000km ?

    Merci pour vos bons conseils et j’en profite. Etant descendu dans le Var, j’ai malheureusement eu un temps de pluie tant à l’aller qu’au retour, je dirai sur 1800 km, voire du brouillard. Jai donc roulé feux allumés, radio, m
