Firstly, if you've filled your vehicle with inferior gasoline, it's advisable not to continue driving. Using subpar fuel can lead to a decrease in vehicle power. Moreover, while idling, you might distinctly notice the engine vibrating with unusual noises.
Furthermore, inferior gasoline typically has poor knock resistance, making the vehicle prone to engine knocking or pinging. Over time, this can result in significant carbon buildup, clogging various components, increasing fuel consumption, and shortening the engine's lifespan. In severe cases, it might even damage the catalytic converter. Repairing such damage can be costly, so it's crucial to address the issue promptly if inferior gasoline has been used.
It's worth noting that some drivers might think of adding quality gasoline on top of the inferior one, hoping it will dilute the damage. This approach is not advisable. The inherent properties of inferior gasoline remain, and adding quality gasoline won't significantly change them. Instead, it might compromise the performance of the quality gasoline.
If you've unfortunately added inferior gasoline, the best course of action is to drain the gas tank and conduct a thorough cleaning of the fuel system. Afterward, refill with high-quality gasoline. Additionally, it's a good idea to remove any carbon deposits from various engine components to prevent further clogging. It's recommended to visit a dealership or auto service center for a detailed maintenance check to ensure the vehicle returns to its optimal performance.
