What are the factors affecting fuel consumption?

Vehicle fuel economy or not is evaluated and calculated based on a wide range of factors. A vehicle’s fuel consumption is influenced by several key factors such as engine, environmental conditions, driving habits, vehicle maintenance, fuel quality, tire problems, and tire alignment. Below are details of the impact of these factors on the fuel consumption of cars.

Car engine

If the engine is not running smoothly, the car will consume more gas than usual. Specifically, the following details have problems that will affect the amount of fuel consumed on the vehicle.

The fuel injection oil controls the amount of air entering the engine. The problem of the injector causes a fuel leak, reducing the amount of fuel reaching the engine, making the car run less efficiently. Meanwhile, engine oil helps reduce friction, lubricate and limit rust for details. When the oil is not replaced in time or the vehicle uses the wrong type of oil, the engine will overheat, operate less smoothly and cause fuel consumption. Spark plug fires due to incorrect operation also lead to fuel consumption problems in the vehicle. When the engine does not receive enough combustion power, the vehicle’s ability to save fuel will be limited.

Currently, car manufacturers have constantly improved and found many ways to improve car engines, contributing to significantly reducing fuel consumption. Leading car manufacturers, such as Toyota, Ford, Honda, etc., have constantly sought to improve to equip turbocharged engines to save more fuel than non-turbocharged engines, using engines with control systems. Electronic injection is more economical than mechanical control. In particular, the EIII engine with electronic control is more fuel-efficient than the conventional EII.

Environmental conditions

Regular use of air conditioning or the number of people in the car, the load of goods exceeding the company’s recommendations all affects the fuel consumption of the vehicle. Next, it is necessary to mention road conditions and moving terrain. On rough, bumpy, or wet surfaces, the car will operate more difficult, and the fuel consumption will also be higher. On the contrary, moving on a flat road will help the car save more fuel.

Cars traveling on open roads or inner-city roads also affect fuel consumption at different rates. With cars often moving in the city, the traffic density is high, and the fuel consumption is higher. As for the car moving on the highway, the road is clear, the fuel consumption is more stable.

In cold weather, the car will take longer to start than usual. Lubricating oil is less effective in cold weather. The density of the air at this time is also denser than usual. For gasoline engines, a certain ratio of carburetors must be created before the car can start. The battery also cannot function properly because the solvent is chemically changed. Lubricating oil is thick, affecting the working efficiency. Air conditioning, heated seats need a lot of energy to operate as usual. Therefore, when we move in cold weather, the level of fuel consumption will increase quite a bit.

Driving habits

Many studies and tests on the fuel consumption of cars have shown that the driver’s driving habits affect fuel consumption. In case the car often runs in the city or brakes suddenly when running at high speed, it can consume 5% – 30% compared to cars that do not have this habit.

Long idle (Garanti) spin times also increase fuel consumption. Not only that, but this also affects the life of the engine and increases emissions into the environment. Driving at too high a speed, surpassing the maximum threshold of the vehicle, results in the vehicle’s engine also operating over the threshold, consuming more energy than running at the correct speed limit of the vehicle.

Maintenance mode

Improper vehicle maintenance easily causes car parts to deteriorate quickly and operate inefficiently. This is one of the main causes affecting the fuel consumption of the vehicle. Specifically, when the air filter has not been cleaned for a long time, it will become clogged with dust, thereby reducing the engine’s performance. In addition, engine oil that has not been changed for a long time is degraded, affecting the ability of the vehicle to operate, etc. In addition, if the car is taken to an unreputable facility for maintenance, the deviations in assembling components and maintenance spare parts also affect the fuel consumption of the vehicle.

Fuel quality 

Using fuel that does not meet the standards recommended by the manufacturer is a factor that makes the vehicle more fuel efficient. A test of fuel for automobiles showed:

  • Vehicles using Ethanol gasoline will consume 1-3% more than standard gasoline.
  • The calorific value of fuel in different seasons also changes, usually summer is higher than winter.
  • For vehicles using gasoline with substandard octane, high impurity content not only affects performance but also increases fuel consumption. Even in some worse cases, the engine can be damaged. Therefore, in order to save fuel and operate well, and increase life expectancy, users should give priority to using fuel of standard quality or recommend by the manufacturer.

Operation of automotive equipment

Tire pressure

Low tire pressure increases rolling resistance on both sides of the tire, causing the vehicle to expend more power to maintain a certain speed within a certain range. According to research, when the tire pressure is up to standard, the car will save fuel up to 3%. Under-inflated tires not only consume fuel but also affect the service life and cost more to maintain. When the car is running on a curve, under-inflated tires cause difficulty in steering, causing danger to the driver.

Therefore, every driver should check the tire pressure before using the vehicle to avoid unwanted accidents. Drivers should consider the standard pressure for their tires, and should not inflate the tire as printed on the tire because that is the maximum pressure that the tire can withstand. Some sedans and small pickups have a standard tire pressure of 27 psi – 31 psi, others can be up to 40 psi (depending on the value given by the manufacturer).

Oxygen sensor

The oxygen sensor is responsible for measuring the residual oxygen concentration in the exhaust gas and sending it to the ECU. Based on this signal, the ECU will know the fuel condition and then give a signal to adjust the amount of injection accordingly. If the sensor is damaged, more fuel will be injected, causing more fuel consumption. The combustion process will not be complete at this time, producing harmful emissions.

Oxygen sensors not working will cause more fuel consumption than usual (about 20-25%). The phenomenon of excess fuel, lack of oxygen also originates from this problem. Not only that, the machine also occurs when running at low speed or idling. So make sure your oxygen sensor is working properly. Sensor repair costs are not only cheap but also help you save fuel, so don’t be afraid to go for maintenance.

Air filter

A clogged air filter restricts the amount of air that flows into the engine. The air filter closes a lot of dirt, causing less air to enter the combustion chamber, which means there will be more dirt due to bad filtration. The car at this time will quickly heat up and increase the amount of soot that clogs the spark plugs. The engine may then turn off suddenly. Therefore, to ensure the car works normally and causes less fuel consumption. We should go change the air filter and check it periodically to make the engine work better.


If the lubricating oil is not changed regularly, the engine will become hotter and hotter due to the friction of the parts. Oils not only have a lubricating effect, but they also have the ability to cool parts and prevent rust. If the burned oil enters the combustion chamber due to the parts not being sealed, it will create soot that causes the oil to thicken. If left for a long time, these cinders will become denser and form many patches. Then the lubricating oil will be a burden on the engine because it prevents the operation of other details.

What is the best way to save fuel?

most fuel efficient cars in canada

Fuel economy when operating a car is always a topic of interest, especially when today’s society gas prices are considered an uncontrollable variable. So how do we limit the impact of this variable? Check out these 7 tips below:

Drive at a moderate speed

When driving we should pay attention or avoid driving at too high a speed on rough and bumpy roads. With the traffic in Vietnam, it is very important to control the speed and distance when driving. More specifically, when the front is a traffic light, it is essential that you estimate the distance and traffic volume so that the car always operates at a speed, which helps to avoid stopping and speeding up.

Turn off the car engine when not needed

To save fuel when operating a car, the most important thing you need to pay attention to is not to let the engine work when it is not needed. In the case of waiting for a red light, if the number of seconds exceeds 30 seconds, you should turn off the engine and let the engine rest, this will help your car save fuel significantly.

Limit the use of air conditioners

If the weather is cool and not too hot, you should turn off the air conditioner to save fuel when operating the car. This is true because according to many studies, air conditioning can consume up to 10% of the fuel of a car. But there is a special case where when you are driving on the highway at a speed of 80km/h, it is better to open the air conditioner than to open a car window.

So how to save fuel when using the air conditioner? You can use insulation pieces on the car windows to limit the impact of outside temperature on the inside of the car. This will help the air conditioner in your car work more efficiently because you don’t have to try to increase the capacity to reduce the temperature too high in the car, thereby reducing fuel consumption when using the air conditioner.

Build up driving plan

It is very taboo to run around, stop continuously and turn around to find the way. Because the traffic volume of the car on the road is very large, if you lose your way, it will consume a lot of fuel. Before starting your journey, it is essential that you make a clear schedule, draw out the routes you need to travel to get to your destination in the most convenient way. This will help you be more active in traffic.

Clean the air filter regularly

The condition of the air filter on the car when it is clogged will cause significant fuel consumption. According to experts’ calculations, if the filter is clogged, it will consume 10% of the fuel. Please clean and expose yourself to the light if you do not see the sun’s rays through the filter, then it’s time to change the filter for your car. To ensure optimal performance and fuel economy for your car.

Regular maintenance

It is not natural that car manufacturers advise drivers to adhere to a maintenance schedule. Regular maintenance will help keep the engine properly maintained and fuel efficiency less. You should watch out for some signs that your car needs maintenance such as worn spark plugs, dirt, problems related to the air purifier, fuel filter, etc. For a diesel vehicle, it will increase fuel consumption if the injectors are dirty. However, drivers often do not pay attention to this sign and ignore maintenance, so they have to pay more for fuel.

Ensure the suitability between the engine and car

From the design stage, the choice of transmission ratios of the powertrain has a great impact on the fuel consumption of an automobile. For a given power, the performance of the motor will improve with increasing load and decreasing speed. Therefore, it is possible to reduce vehicle fuel consumption if the transmission ratio of the transmission is selected so that the engine operates at a lower speed for a given vehicle speed.

Above is information about factors behind fuel consumption, the most fuel efficient cars in Canada, and tips to save fuel during car operation. We do hope that this article can be beneficial for you so that you can choose your best fuel economy cars.
