A group of automakers first created Top Tier gas back in 2004 to benefit the driver. It must include specific additive formulations in all octanes for gasoline to earn the Top Tier label.

According to the American Automobile Association (AAA), engine carbon deposits reduce dramatically with Top Tier gas.

But, that is not the only benefit of Top Tier gas. Some of the other advantages to this type of gasoline include:

  • Better drivability
  • Better fuel economy
  • Fewer emissions

Although Top Tier gas costs an average of $0.03 more per gallon than other brands, the personal and environmental benefits make up for the additional cost.
