Why clean your engine’s injectors?

Unstable idle? Power loss? Over-consumption of fuel? These signs often indicate clogged injectors. A preventive or curative cleaning can restore the engine’s proper functioning before the damage worsens… and the bill climbs.

Over time, injectors accumulate deposits of carbon or unburned fuel, which disrupt atomization. The result: irregular combustion, difficult starting, excessive smoke or even engine misfiring. Injector cleaning helps to:

  • Restore optimum atomization and cleaner combustion
  • Reduce fuel consumption
  • Improve power, smoothness and starting performance
  • Extend engine and injection system life
  • Prevent clogging of valves, pistons and catalysts

At Alex Pneu et Mécanique, we don’t just pour in an additive. We perform targeted cleaning using professional tools, after assessing the actual condition of your injectors. You leave with a healthier, better-performing engine – and a no-surprise service

Frequently asked questions about injector cleaning

What are injectors for?

Injectors spray fuel into the combustion chamber. They must work precisely to ensure good performance, controlled consumption and clean combustion.

What are the signs of clogged injectors?

  • Unstable idle or “chattering” engine
  • Difficult cold start
  • Loss of power on acceleration
  • Increased fuel consumption
  • Black smoke emissions or unburned fuel odors

How often should you have your injectors cleaned?

Usually every 40,000 to 60,000 km, or according to the manufacturer’s recommendations. It also depends on your driving style, fuel quality and usage (city, highway, short trips)

Is cleaning useful for all engine types?

Yes. Whether you drive a petrol, diesel, GDI, FSI or TDI engine, cleaning preserves performance and prevents wear on the injection system. This is particularly important for direct-injection engines

Is cleaning always enough to solve problems?

Not necessarily. If the injectors are too worn or damaged, they will have to be replaced. That’s why at Alex, we always start with a diagnosis before intervening.

What are the advantages of professional cleaning versus fuel additives?

Additives are often too light to dislodge encrusted deposits. Professional cleaning uses specialized equipment, without dismantling the engine, for a more complete and lasting result

Does injector cleaning really improve performance?

Yes. After a good cleaning, we often notice a smoother engine, sharper acceleration and reduced fuel consumption. It’s maintenance that brings the engine back to life.
