Find out why your car uses so much fuel and how adjusting small details can transform performance and save money at the gas station.
Imagine the following scene: you are always keeping an eye on the fuel gauge, and every time you go to the gas station, the scare is the same. It seems like the tank evaporates, and you can barely make it through the week. If the your car uses a lot of fuel, you are not alone. The feeling that every drop costs a fortune has made many people look for ways to make the car more economical. But is there a magic formula? Spoiler: no. However, with some expert tips and attention to detail, you can ensure that your vehicle consumes less and your wallet will thank you!
We listened to the expert from DR Auto Mecânica to understand the main reasons for a car consumes a lot of fuel e what simple tweaks can transform it on a most economical car. Below, we detail how each part of your vehicle influences consumption and what you can do to optimize the performance of your tank.
Why does your car use so much fuel?
According to the DR Auto Mecânica specialist, the first step is don't fall for miraculous promises. Many products on the market claim to reduce fuel consumption, but the reality is that no device will make the car more economical than designed by the automaker. Factories are constantly seeking to improve engine efficiency, as is the case with the latest three-cylinder models, which are made precisely to spend less.

“If it were something really effective, it would already be out of the factory”, warns the expert. In other words, be careful with miracle products that promise to transform your car into a low-energy vehicle. The key is maintenance.
Maintenance: The secret to a more economical car
If the your car uses a lot of fuel, maybe it's time to check out some basics:
1. Worn spark plugs:
Spark plugs are responsible for burning fuel inside the engine. If they are old or burning unevenly, your car will need more fuel to compensate for the lack of efficiency. Changing spark plugs regularly ensures better combustion and lower consumption.
2. Lambda probe working correctly:
This sensor, located in the exhaust, measures the amount of oxygen in the exhaust gases and adjusts fuel injection accordingly. A worn sensor can cause the engine to inject more fuel than necessary. Keeping the lambda probe in good condition is crucial for economic performance.
3. Dirty butterfly:
The butterfly valve regulates the air intake into the engine. If it is dirty, the air flow is compromised, which can increase consumption. Proper cleaning of this component ensures that your car breathes better and consumes less.
Small details, big savings
In addition to preventative maintenance, some adjustments to behavior and driving can help a lot:
1. Keep the air filter clean:
A clogged air filter limits the oxygen entering the engine, forcing the car to use more fuel to compensate. Changing your filter regularly is one of the simplest ways to ensure your engine runs smoothly.
2. Check the thermostatic valve:
It is responsible for controlling the engine temperature, keeping it warm enough for efficient fuel combustion. If it is stuck open, the engine may run cold and use more fuel. Replace the thermostatic valve whenever recommended to avoid unnecessary expenses.
Be careful with the compression ratio
If you have checked all of the above and still feel that your car uses a lot of fuel, the problem may be in the engine compression ratio. Low compression means that the fuel is not being burned efficiently, increasing consumption. DR Auto Mecânica recommends that the compression ratio be checked by a trusted mechanic, especially in cars with high mileage.
How electronic management can help
Many drivers believe that going down a mountain with the car disengaged saves fuel, but this is a big myth. Leave the car in gear and using the engine brake is the most efficient way to save, as the electronic injection system understands that the engine does not need fuel while you are going downhill.
Final tips for saving fuel
Finally, some simple actions can make all the difference in fuel economy:
- Keep your tires inflated: Under-inflated tires increase friction with the ground, forcing the engine to work harder.
- Avoid sudden acceleration: Driving smoothly and avoiding unnecessary braking and starting can significantly reduce consumption.
- Don't carry unnecessary weight: The lighter the car, the less effort the engine will make, reducing fuel consumption.
Now that you know how to maintain your most economical car, how about checking your vehicle? Your car uses a lot of fuel Or do you already do preventive maintenance properly? Share in the comments your experience or questions, and let's continue this conversation!
