(Baonghean.vn) - With advanced technology, cars all have modern devices to save fuel. However, improper use will make your car consume more fuel and be inefficient.

The following tips will help drivers perfect their driving skills to achieve the best fuel economy.

Check ignition system

Misfires may occur infrequently, but they do consume about 10% more fuel. Poor quality spark plugs and high resistance high voltage wires are the source of this problem.

Clean air filters regularly

According to experts, if the filter is clogged, it will waste 10% of fuel. But the air filter is easy to remove. So, clean it and dry it in the sun. If you do not see light through it, it means you need to replace the filter. When you see the filter is clogged many times, you should replace it with a new one to ensure the air filtration process is smooth and save fuel.

Pay attention to the car windows

When driving at low speeds, roll down the windows. But when driving at high speeds above 80km/h, opening the windows will increase the car's wind resistance, causing the car to consume more fuel than normal. Therefore, close all the windows when driving at high speeds.

No need to fill up the tank

A gas tank, depending on the type, is usually from 50 to 60 liters, which is equivalent to about 35 to 42 kg, this weight is quite a lot, so pour in a moderate amount of gas for the journey, the less gas, the lighter the vehicle, the more fuel efficient it is.

Don't go at high speed

Slowing down from 100km/h to 80km/h can reduce fuel consumption by 10% to 15%. Drive in a high gear with a low engine speed (rpm), ideally between 1,500 and 2,500 rpm to maximize fuel economy.

Don't rev the gas too much.

Another way to say it in the automotive world is to “rev up.” Researchers have proven that driving carefully, without constantly accelerating and decelerating, will help you save fuel significantly. According to the US Environmental Protection Agency (EPA), accelerating slowly can save up to 33% more fuel on the highway and 5% in the city.

Check your tires regularly

Regularly checking your tire pressure is important for a number of reasons. Not only does underinflated tires make it harder to control and brake, but the drag created by underinflated tires also increases your engine’s fuel consumption. Keep your tire pressure at the level specified by your vehicle manufacturer and you’ll save a pretty penny.

Turn off engine when stopping

Many cars now have the smart Start/Stop function. This function will turn off the engine when your car stops and turn it back on when you want to drive away. If your car does not have this function, you can do it manually. Today's car engines use electronic fuel injectors that can very tightly control the amount of fuel delivered to the engine when the car starts, so your car will almost not use fuel during the starting process.

So how long should you stop before turning off the engine? The answer is more than 10 seconds. This number also depends on the model of your car, it is usually longer for older models. Restarting too often will also have a certain effect on the battery and ignition mechanism of the car.

Take advantage of aerodynamics

To put it simply, it is the wind resistance when you move. If you increase the wind resistance, it means your car will consume more fuel. To reduce that factor, you can pay attention to some points such as not opening the window while driving, especially when moving on the highway, moving at high speed.

For pickup trucks that are empty or do not need to be loaded, drop the bed door and remove the roof rack.

Reduce weight on the vehicle

In addition to engine factors, vehicle weight is a factor that directly determines the fuel consumption of the vehicle. The simplest way to reduce unnecessary fuel consumption is to remove all unnecessary items from the vehicle and leave only what is really necessary. Because every 50 kg of luggage will consume 2% more fuel.

Use higher number

Many drivers tend to drive in low gears for too long, making the engine work harder than necessary and consuming more fuel as a result. Shift up/down at 2,500rpm for petrol-powered vehicles and 2,000rpm for diesel-powered vehicles.

Use the right type of engine oil

Drivers can save 1-2% on fuel by using the correct oil recommended by the manufacturer. According to the US Environmental Protection Agency (EPA), using 10W-30 oil in an engine that requires 5W-30 will increase fuel costs by $0.04-0.07 per gallon (3.8L). In addition, it can help maintain performance and prolong engine life.

Cruise control

Using this technology when traveling on the highway helps stabilize speed, increasing the distance traveled by 7%. But do not use on mixed roads, streets, cruise control will not be able to take effect.

Use cruise control

This is an automatic speed control system that has appeared on many modern cars today. For example, when set at 112km/h on the highway, the computer will calculate and adjust the throttle valve to maintain that speed, helping to save fuel for the car.

Even more effective is the Adaptive Cruise system, which uses radar to maintain distance from the vehicle behind and in front.
