QuikTrip: Top Tier Gasoline

TULSA, Okla.--June 18, 2004--QuikTrip Guaranteed Gasoline has been approved by a group of automobile manufacturers as a Top Tier Gasoline. This group is composed of General Motors, Toyota, Honda and BMW, automakers who are concerned about the low levels of detergent additives in gasoline. These companies have created a new voluntary deposit control standard for gasoline that exceed those of EPA's deposit control rule. Their purpose is to define a new class of commercial gasoline with enhanced detergency called Top Tier Detergent Gasoline.

Over the past several years, the minimum level of detergent additive required by the EPA has declined by an estimated 50%. As a result, the ability of vehicles to maintain stringent Tier 2 emission standards have been hampered, leading to engine deposits which can have a big impact on in-use emissions and customer satisfaction.

QuikTrip Guaranteed Gasoline with the IQ additive is one of the first to be recognized as meeting the Top Tier standards. QuikTrip has maintained a high additive level for several years, so meeting the Top Tier requirements was easily attained. All grades of QuikTrip Guaranteed Gasoline meet the Top Tier requirements.

"QuikTrip applauds these manufacturers for raising the standards for gasoline additives," said Rick Calhoun, QuikTrip Vice President for Petroleum Operations.

"By meeting the Top Tier standards, we can assure our customers that QuikTrip Gasoline with IQ will help clean their engines as they drive while producing lower emissions."

QuikTrip Corporation is a privately-owned gasoline/convenience store retailer with 433 stores in nine states. QuikTrip stores annually sell 1.8 billion gallons of gasoline products.
