Poor-quality fuel and adulterated petrol can indeed have a negative effect on the Prius’ fuel efficiency:

Adulterated fuel can cause incomplete combustion, leading to lower engine efficiency, reduced power, and increased fuel consumption.
Low-octane fuel may cause knocking, forcing the engine to work harder to maintain power and reduce fuel economy.

Precautions:

Buy fuel from reputable stations to ensure quality.
Use high-octane fuel if the engine shows signs of knocking o r poor performance with standard petrol.
