An old car that consumes too much fuel is always an obsession of car owners. Cars that consume a lot of fuel make the vehicle owner financially expensive and make the car deteriorate quickly. Solving this situation is a huge question mark for many people.

This article will show you why a car won’t take Gas and recommend some solutions for you to solve it. Let’s explore now!

The Reason Why Car Won’t Take Gas

The Common Question You Need To Know

Lack Of Cool Water

Coolant is one of the parts that are rarely cared for, but it brings many benefits for your car. Coolant is an important component that helps cars reduce hot air from the engine. That’s why the car’s cool sensor is always designed close to the side of the car’s engine.

Cool water is like engine oil. Cool water balances the thermodynamics in the engine compartment and supports the engine to operate more smoothly.

There are many types of car coolants with different chemical compositions. So when mixing cool water, you mix it in a 1:1 or 6:4 ratio of cool water and distilled water.

When the car is operated for a long time, the cool water will balance the heat and pressure for the best operation of the engine parts. If the cool water is exhausted, it can cause fuel injection into the engine to increase.

It causes the car engine to operate with great capacity, and then the car won’t take gas.

Clogged Fuel Filter

It can be considered as one of the reasons that few people pay attention to. The car’s engine is an almost closed combination, so a bad impact on one part will lead to the failure of another part.

During operation, cars will emit dust and soot. This dirt and soot accumulated for a long time without cleaning will stick to the engine, cylinder, or spark plugs.

From there, the compression pressure of the machine parts can change. And eventually leading to fuel consumption, damage, or even engine inertia.

Dirt and soot build-up in the engine has a great effect on the car’s engine. You should change the dirty fuel filter because the harm of this dirt is unbelievable:

  • When dirt builds up around the cylinder, it will lead to engine inertia due to a decrease in its compression ratio.
  • When dirt accumulates inside the engine, it will reduce the efficiency and durability of the engine.
  • When dirt clings to the injectors, the engine will fall into overdrive, affecting engine life.

Engine Oil

The lubricant has the effect of reducing friction between machine parts in the engine. When the engine oil is old or of low quality, it will consume 12% more fuel than normal. Therefore, car owners should change the oil periodically and use the right oil for the engine to make the car operate more smoothly.

Issues With Spark

Worn, dirty spark plugs will cause the ignition process to fail, leading to a situation where the fuel and air mixture does not burn completely or is abandoned. 

At this time, the engine ignition will not achieve the highest efficiency. The engine must work more to compensate, causing the car to lose fuel. Worn, dirty spark plugs easily lead to many errors, such as the car is difficult to start, the car stalls in the middle of the road, the car is jerked when getting on the Gas.

What To Do If The Car Won’t Take Gas?

To avoid the car won’t take Gas, car owners should actively check and maintain the car periodically. You can also use the following methods:

Clean The Area Around The Fuel Tank

It’s easy for things to get clogged in the EVAP system, so keeping your fuel tank cap area clean is important. I used to think I could ignore the dirt around my EVAP area and minimize my time spent cleaning it, but that’s not the case. 

When you neglect your EVAP system, the chances are that your engine won’t run well until you resolve the issue or pay someone to do it instead. Therefore, you should clean it frequently, at least once a week. 

Replace The Evap Charcoal Canister 

If the vehicle detects a sudden drop in fuel pressure, you should replace the EVAP charcoal canister. This engine helps to protect the environment because it will avoid hydrocarbons and push the fresh air into our atmosphere. Therefore, you can avoid not taking Gas and environmental pollution. 

How Can We Recognise Bad Gas?

Poor quality gasoline is the cause of many diseases in the car, such as difficulty starting the car, making unusual noises, and even leading to a car fire. Poor quality gasoline is caused by the manufacturer intentionally mixing gasoline with water or other chemicals. 

In addition, if there is a phenomenon of adhesion (greasy), it is the gasoline that has been mixed with oil, so do not buy it.

The best way to avoid encountering poor quality gasoline is to buy at gas stations that are reputable dealers and where you have experienced fuel quality there. It will help you keep a relatively even fuel quality.


We have outlined the most common reasons why a car won’t take Gas and simple solutions for you through this article. You should clean the car regularly and maintain the engine periodically to keep the car in the best condition. If you have any questions, we are always ready to help.
