Gas stations in any country are required to supply customers with consistent and pure gasoline. No matter where the tank gets filled up, gas quality or the brand of gas will not noticeably affect how the vehicle performs. Some brands offer fuels with added cleaners and other additives. These can offer some benefits, but the fact remains that cheap gas that doesn’t contain these additives is not dangerous or problematic.

Impurities in the gas will definitely affect the performance of your vehicle. It might be affecting your vehicle engine performance because the fuel is directly flowing in the engines inlet valves and after the combustion, it will be going out through the outlet valve.

As automotive technology has advanced in recent decades, automakers around the world agreed that government requirements for fuel additives were not adequate since they have not changed to meet the performance demands of modern vehicles. If a fuel company can prove that their gas has additives and detergents that keep residue from building up on valves or in the combustion chamber, then they are qualified to call themselves a “top-tier” gasoline supplier. Top-tier fuel is formulated to keep engines running efficiently and reliably. Automakers claim that these requirements make gas better for modern cars.
