Why is your car consuming more fuel than usual?

At Mario Garage in Cagnes-sur-Mer, many of our clients come in with the same question: "Why is my car using so much more fuel than before?"

It's a valid concern — especially with today’s fuel prices. And in most cases, it’s not just your imagination. There’s always a technical reason behind it.

What you need to know: high fuel consumption is not normal

Even powerful engines are designed to run efficiently. If you notice your tank emptying too quickly, something isn’t working properly under the hood.

Here are the most common causes we see in our workshop:

* Tire pressure too low

* Faulty sensors (lambda sensor, mass airflow sensor, etc.)

* Worn spark plugs or clogged injectors

* Dirty air filter

* Constant city driving with frequent stops

* Incorrect air/fuel mixture

Sometimes, it’s a sign of something more serious

Loss of power, engine vibrations, or strange smells can all point to a deeper engine problem. In such cases, the engine has to work harder, and fuel consumption skyrockets.

The worst part? Some drivers get used to the excessive fuel use and stop noticing it… until a major breakdown happens.

Why get a diagnostic at our garage?

At Mario Garage, we don’t just check your oil level. We connect diagnostic tools, inspect sensors, test injectors, and listen carefully to how your engine runs.

We specialize in German vehicles — BMW, Mercedes, Audi, Volkswagen — and we explain everything clearly and without technical jargon.

When should you come in?

* If you're driving fewer kilometers per tank than before

* If your car is slow to accelerate

* If the engine runs unevenly

* If you clearly see that fuel usage is above normal

Don’t wait for a breakdown. Come in for a fast, precise diagnostic at Mario Garage in Cagnes-sur-Mer.

You’ll save fuel — and maybe avoid a major repair bill.
