What Is Top Tier Gas?

In order to sell as Top Tier, gasoline has to meet certain licensing, processing, and certification requirements. Top Tier gas goes through a certain level of oil deposit control additives. This leads to fewer air pollutants, higher fuel economy, and less carbon output.

Sam’s Club does not sell Top Tier gas, but that doesn’t mean their gas is low quality. The EPA has rigorous standards for fuel quality across the board.

What Octane Levels Does Sam’s Club Gas Have?

Sam’s Club premium gas boasts an octane grade of 91, which is in the high-quality range. Higher-quality fuel is better for your engine and the life of your car.

This can cause damage to your engine and place more pressure on the engine’s pistons.

Sam’s Club premium fuel does offer a good level of octane. This means your engine will hopefully run smoothly, with no knock.
