Have You Heard That Preventive Cleaning of Fuel Injectors Is Essential for the Proper Functioning of the Car? But Is It Really Necessary or Just Another Scheme by Mechanics to Rip You Off?

Fuel injectors are essential parts for the car, responsible for distributing fuel in the engine. CPG spoke with experts from DR Auto Mechanics, and according to them, they already come with a self-cleaning system. In other words, while the fuel passes through the injector, it performs a natural cleaning, eliminating the need for a constant cleaning procedure. However, many mechanics claim that preventive cleaning is indispensable and recommend the service at almost every maintenance check.

Is Preventive Cleaning of Fuel Injectors Really Necessary?

DR Auto Mechanics, with over 30 years of experience, states that cleaning fuel injectors is only genuinely indicated when there are specific performance failures in the vehicle, such as loss of power, difficulty starting, or excessive fuel consumption. According to them, this practice should not be part of preventive maintenance unless the injectors are showing clear problems.

The professionals explain that, in addition to a filter at the inlet of the injectors, the fuel also passes through other filters throughout the system, which prevents a large part of the impurities from reaching the fuel injectors.

When Is Cleaning of Fuel Injectors Really Necessary?

According to DR Auto Mechanics specialists, it is essential to perform injector cleaning only in specific cases. They explain that if the car shows symptoms of injector problems, such as combustion failures, cleaning can be done on an ultrasonic machine.

This equipment uses vibrations to remove dirt particles from inaccessible areas of the injector, ensuring a deeper and more efficient result.

“It is important to replace the internal filter of the fuel injectors and not rely only on external cleaning,” advises the team at DR Auto Mechanics. This replacement of the filter can help extend the life of the injector, especially in cars that use alcohol, a fuel that tends to leave more residues in the system.

Be Careful with Dubious Refueling

In addition to highlighting the importance of cleaning only when really necessary, the specialists warn about the quality of the fuel. Refueling at low-reliability stations can result in accumulated dirt in the injectors, harming not only the fuel injectors but also other components of the engine.

According to DR Auto Mechanics, preventive cleaning of fuel injectors often amounts to a scam to increase maintenance costs.

The practice is only recommended if there are real problems in the functioning of the injectors and, even so, should be performed with specialized equipment, such as the ultrasonic machine. Therefore, stay alert and, at the next maintenance check, question your mechanic about the real need for this service.

A giant printer called the “Ferrari” of concrete has landed in Latin America and can already build a 120-square-meter house in just 48 hours, making the traditional construction site look like something from the last century.

Brazil will harvest a record crop of up to 357 million tons of grains, but it does not have the capacity to store a large part of it. The storage deficit has reached the highest level in history and is equivalent to almost the entire production of Argentina.

Four times faster than the Concorde, capable of taking passengers from New York to London in less than an hour at Mach 5.5, and with an engine that switches from turbojet to ramjet mid-flight at Mach 3.5, the Hermeus Quarterhorse went from paper to its first flight in just 19 months.

Under nearly 2 kilometers of ice in Antarctica, scientists have discovered an ancient landscape sculpted by rivers up to 60 million years ago, the size of Wales, preserved as a time capsule that could help predict the advance of ice towards the ocean.

She started by collecting oyster shells from restaurants and today she has already accumulated more than 10 tons to restore reefs, recover coastal habitats, and demonstrate how a common waste can become a tool for ocean conservation.

SpaceX will dock a $843 million vehicle to the International Space Station to push a nearly 420-ton laboratory against the atmosphere and make the debris fall in a controlled manner into the ocean.

For the economist José Kobori, the USA gained a trump card to “blackmail” Brazil and undermine China’s influence by classifying the PCC and Comando Vermelho as terrorists, increasing the power to pressure companies, banks, and even Pix.

BYD Atto 2 DM-i flex prepares to debut in Brazil with a plug-in hybrid engine, national assembly in Camaçari, competitive pricing, and targets Creta and T-Cross in a battle that promises to heat up the compact SUV market.

Processors can become 1,000 times faster with a new device that uses light pulses, operates in 40 picoseconds, and reduces the heat that stalls data centers.

Noise in the sky frightened residents: NASA confirms that a meteor exploded over New England with a force equivalent to 230 tons of TNT

The paycheck that seemed impossible: São José employee receives R$ 7.94 after legal strike, while deductions by the City Hall affect over a thousand employees and become a target of inquiry in the City Council.

Mitsubishi confirms the triumphant return of a car beloved by Brazilians that was discontinued after almost 40 years, based on the Triton, 4×4, and targets rival Toyota Land Cruiser in a plan of 13 SUVs.
