Top Tier Fuel

At every Market Express location, we serve Top Tier gasoline and diesel. While many large retailers give you the lowest quality fuel required by federal regulation, Top Tier fuels are recognized as premier products. 

The largest difference of Top Tier gasoline is the higher detergent standard. Top Tier Detergent Gasoline was first introduced in 2004 when a group of automakers recognized the need for a higher detergency gasoline standard than that required by regulation.

  • “Among brands tested, non-TOP TIER gasolines caused 19 times more engine deposits than TOP TIER brands after just 4,000 miles of simulated driving. Such carbon deposits can reduce fuel economy, increase emissions and negatively impact vehicle performance, particularly on newer vehicles.”
