Fuel quality in Pakistan varies, and some petrol stations may supply fuel with lower octane ratings o r adulterated fuel containing impurities. Using low-quality o r adulterated fuel can lead to incomplete combustion, engine knocking, clogged fuel injectors, and buildup of deposits in the engine. This results in reduced fuel efficiency, rough engine performance, and potentially long-term damage. Mercedes-Benz engines, which are finely tuned for higher quality fuel, are especially sensitive to poor fuel quality. To protect the engine and maintain good fuel economy, owners should buy fuel from reputable stations, consider using fuel additives designed to clean the fuel system, and have the fuel injectors and engine components cleaned regularly.
