Someone might say that a car was made to stay dirty. Oil, pistons, exhaust system, gearbox – everything gets dirty yet continues to perform roughly the same. However, there is one engine component that suffers significantly from contamination and loses its efficiency without proper care, namely – injectors.
Dirty injectors can cause a range of problems and lead to significant performance loss. Let’s examine these cases together and see how we can protect our car from them.
How to determine if the injectors are critically clogged?
After a period of use, injectors begin to accumulate fuel combustion residues in the engine. Both gasoline and diesel fuel are derived from oil, which is not the “purest” compound in the world, and their combustion always produces significant emissions and deposits.
If these residues build up, the engine starts to burn fuel less efficiently and may even have difficulty transporting fuel.
Here are the most common symptoms of clogged injectors:
- High emissions, noticeable after a technical inspection.
- Reduced engine performance with higher fuel consumption.
- Ignition problems. This can include knocking and strange noises when starting the engine.
- Sharpness and unpredictability in the car’s operation
Injector cleaning methods
We will look at the three most common cleaning options:
- Disassembly of the injector and ultrasonic cleaning
- Disassembly of certain injector parts and cleaning with compressed air
- Cleaning the injector using additives
Methods that require injector disassembly cannot be performed without a specialist’s involvement. Not only because they require specific knowledge, but also because they need professional equipment.
Of course, there are some tools for amateurs, but they can be demanding and inconvenient for most drivers. Moreover, there is a risk of damage.
Professional injector cleaning with no effort
If you would like to care for your car but don’t want to get dirty – we offer you: Ultimax Petrol.
Just one dose of Ultimax Petrol before refueling. Then drive about 30 kilometers at high speeds. And that’s it… You will see the result immediately.
If after this you still want to comprehensively and proactively care for the engine’s injectors – we offer you the following solutions:
- Our Complex Petrol used twice a year protects against any faults. It’s best for keeping the engine in top condition.
- If your vehicle is often under load, or you have recurring injector issues due to (poor part manufacturing, low‑grade fuel…or whatever) then we recommend our Petrol Multi Conditioner.
