Yes, fuel quality has a significant impact on fuel economy:

Low Octane o r Adulterated Fuel: Using fuel with lower octane than recommended o r adulterated fuel can cause incomplete combustion and engine knocking, reducing efficiency.

Contaminants: Impurities in fuel can clog injectors and filters, leading to poor engine performance.

Fuel Additives: Poor-quality fuel may lack necessary additives that help clean the engine and maintain performance.

Recommendations: Always buy fuel from reputable stations, consider using fuel additives o r cleaning services, and follow the manufacturer’s fuel grade recommendations.
