Does the turbonator increase gas mileage?

No, a Turbonator (or any similar aftermarket device claiming to increase gas mileage through the intake) does not increase gas mileage. These devices are generally ineffective and often detrimental to engine performance and longevity. They are usually nothing more than a gimmick.

While they might slightly alter the sound of the engine's intake, the claimed increase in gas mileage is not supported by scientific evidence or reputable testing. In some cases, they can even *reduce* gas mileage due to increased air resistance or by disrupting the carefully engineered airflow of the engine.
