Gasoline cars are a popular means of transportation, using an internal combustion engine to convert chemical energy from fuel into mechanical energy, creating movement. During operation, the amount of fuel in the gas tank gradually decreases and can lead to exhaustion.
Running out of gas Not only does it cause serious damage to vehicle parts, reducing performance, but it also causes costly repairs and poses many potential dangers when participating in traffic.
To avoid unnecessary damage, pay attention to signs that your car is running low on gas, such as the gas warning light, jerking, loud gas pump noise, and unstable engine operation.
The secret to driving safely, saving fuel and avoiding running out of gas on the road is to regularly monitor the gas gauge, plan your trips wisely, maintain your car carefully and practice economical driving skills. Only then can you avoid serious consequences during the use of your car, leading to a loss of money and health.
According to a survey by the Vietnam Automobile Association, up to 68% of drivers have run out of gas on the road at least once. This shows that this is a common problem that many drivers may encounter.
If you are still subjective about the above situation, this article will help you understand the potential harms of driving when the gas is almost out. Follow now to equip yourself with the right knowledge for your car.
Driving with an empty fuel tank not only damages important parts of the vehicle such as the fuel pump, injectors, catalytic converter, engine, and performance, but also poses many potential dangers when participating in traffic.
The fuel pump plays an important role in transporting fuel from the fuel tank to the engine. When the fuel runs out, the fuel pump must operate in a fuel-starved condition, leading to overheating, increased friction and reduced fuel pump life.
According to statistics from auto maintenance centers, the cost of replacing a fuel pump can range from 2-5 million VND, depending on the type of vehicle and the extent of damage. For some high-end cars, this cost can even be up to 10-15 million VND.
When the fuel tank is empty, the injector can accumulate dirt, blocking the injector holes, leading to reduced engine performance and not being able to spray the required amount of fuel. Specifically:
Cleaning or replacing injectors can cost between 1-3 million VND per injector, depending on the level of damage and the type of vehicle. For some high-end vehicles, this cost can be up to 5-7 million VND per injector.
Running on empty fuel can cause overheating, damage the catalyst, increase harmful emissions into the environment and affect engine performance.
According to studies, a properly functioning catalytic converter can reduce harmful emissions by up to 90%. However, when it fails, this efficiency can drop to just 30-50%.
The cost of replacing a catalytic converter can be up to 10-20 million VND, depending on the type of vehicle and the extent of damage. For some high-end or imported cars, this cost can even be up to 30-50 million VND.
When a car is running low on fuel, the engine can experience serious problems such as lack of lubrication, increased temperature, reduced power, ECU damage and sensor failure, leading to poor performance and high risk of damage.
According to experts, regularly running a car on empty can reduce the life of the engine by 10-20%. A normal car engine can operate from 200.000 to 300.000 km before needing an overhaul, but if you regularly run the car on empty, this number can drop to only 150.000 to 200.000 km.
In addition to the technical harm, driving with low gas also poses many serious dangers such as sudden engine failure, loss of control, causing traffic jams, and the risk of rear-end collisions. This can directly threaten traffic safety and the lives of road users.
Statistics show that about 5% of traffic accidents involving cars are caused by the car running out of fuel suddenly. This number increases to 8-10% for accidents that occur on the highway.
Cars running low on gas often have signs such as flashing fuel indicator light, gauge needle pointing to E, car jerking, loud fuel pump noise and unstable engine operation.
The fuel gauge light is the most visual indicator of your vehicle's fuel level. Usually located on the dashboard with a fuel tank icon, it is yellow or red when lit.
The fuel indicator light works based on the fuel level sensor located in the fuel tank and uses the float principle to measure the remaining fuel. When the fuel level is about 10-15% of the tank capacity, the indicator light will appear.
The fuel gauge provides more detailed information about how much fuel is left in the tank. Located on the dashboard, usually on the right or left side, it has markings ranging from F (Full) to E (Empty).
The fuel gauge also works based on the fuel level sensor, but provides more detailed information than the fuel light. Note that the fuel gauge's accuracy can vary by about 5-10%, depending on the vehicle and road conditions.
When the fuel level in the tank gets too low, the vehicle may jerk. This is because the fuel pump cannot draw enough fuel to the engine, which can draw air into the fuel system. Symptoms include jerking and shaking, especially when accelerating or going uphill. This condition will get worse as the fuel level decreases and can cause damage to the engine and transmission.
According to experts, if the car jerks due to lack of fuel, you should find the nearest gas station immediately.
Unusual noises from the fuel pump are an important warning sign. Usually heard from the rear of the vehicle, where the fuel tank is located, the noise is characterized by a high-pitched, continuous noise that is different from the normal engine noise.
This is because the pump has to work harder to suck up the little fuel left, and there is not enough fuel to cool and lubricate. When you can clearly hear the pump making noises, it is a sign that it is working too hard and is at risk of failure.
When the fuel level is too low, the engine will not operate properly. The engine speed will fluctuate, the engine may make strange, uneven noises, and the vehicle may suddenly lose momentum and have difficulty accelerating. This condition can cause many serious problems such as increased fuel consumption, reduced engine power, and increased emissions.
If you notice that the engine is not working properly, especially when the fuel gauge is almost empty, you should immediately find a way to refuel to avoid serious damage that may occur to the engine.
To ensure a safe and efficient trip and avoid running out of gas unexpectedly, regularly monitor the gas gauge, plan your trip appropriately, maintain your vehicle regularly and practice fuel-efficient driving.
Regularly monitoring the fuel gauge is an important habit to avoid running out of gas on the road. Make it a habit to check the fuel gauge every time you get in the car and refuel when the needle is at 1/4 tank to ensure safety. You can also use fuel consumption tracking applications on your smartphone to better manage.
According to a survey, 68% of drivers who regularly check their gas gauges rarely run out of gas on the road.
Research your route before you set off, especially for long trips. Locate gas stations along the way and calculate how much gas you need for the entire trip, with an extra 10-15%.
One study found that careful travel planning can save up to 15% on fuel and reduce the chance of having an accident on the road by 20%.
Perform vehicle maintenance according to the manufacturer's schedule, check and replace fuel and air filters periodically, and ensure tire pressure is always at the correct level.
According to the Society of Automotive Engineers (SAE), proper vehicle maintenance can save 5-10% on fuel and extend vehicle life by up to 20%.
Practicing fuel-efficient driving is an important skill that every driver should learn. Avoid sudden acceleration and braking, maintain a steady speed when traveling on the highway, and use ECO mode (if your car has it) to optimize fuel consumption.
Experts estimate that adopting fuel-efficient driving techniques can reduce gasoline consumption by 10-20%.
Yes. The fuel filter can clog more quickly due to the dirt that accumulates at the bottom of the fuel tank. The filter life can be reduced by 30-50%, from 30.000km to 15.000-20.000km.
Gasoline stored in plastic containers is good for about 3-6 months. After this time, the gasoline may oxidize, lose quality, and may damage the engine.
Possibly. When the engine is running unstable due to lack of fuel, the temperature can increase, putting pressure on the cooling system. This can reduce the life of the water pump and radiator by about 5-10%.
Not recommended. Fuel additives are not a substitute for proper fueling. Improper use of additives can damage the engine and void your warranty. Instead, fuel should be filled promptly when the tank is about 1/4 full.
Maybe. “Eco mode” can save 5-10% fuel by optimizing the response of the accelerator pedal and Car gearboxHowever, this is only a temporary solution and cannot replace timely refueling.
Yes. Turbochargers need to be lubricated and cooled by engine oil. When the gas runs out, the engine runs unstable, which can affect the oil pressure, causing damage to the turbo. The cost of replacing a turbo can range from 15-30 million VND depending on the type of vehicle.
There is an indirect effect. When the engine runs unstable due to lack of fuel, it can affect the electrical system, including the ABS system. This can reduce braking efficiency and increase the risk of an accident by about 20-30% in slippery road conditions.
