You may wonder, which gas station has best quality gas? Chevron. Of America's largest nationwide chains, Chevron scores the highest points in overall customer satisfaction.

Similarly one may ask, is there really a difference in gas quality? The short answer is 'no. ' There is no difference no matter where you buy your gas. In fact, Triple-A says it's more a myth than anything else. However, that is not to say different companies will add their 'flavor' or detergents in the gasoline with the promise of a more fuel-efficient ride.

Besides above, do all gas stations have the same gas quality? No, there's no difference in gasoline itself but brands do mix in different additives. The EPA and state set minimum standards for fuel and additives but many companies exceed minimum requirements.

Likewise, does lower quality gas burn faster? Lower octane gas burns quicker than higher octane, and so require less energy to ignite. However, this also means that lower octanes burn more quickly in high pressure environments, and can have a greater tendency to knock. Knocking occurs when the gasoline is burning fast and is also under high pressure environments.
