Marathon-Branded Gasoline Gets Top Tier Nod

FINDLAY, Ohio — Marathon Petroleum Corp.-branded gasoline with STP additives has been Top Tier certified.

Top Tier certified gasoline is a standard for gasoline performance. The certification means the fuel is going beyond the level of detergency additives required by the U.S. Environmental Protection Agency, fighting the accumulation of harmful deposits and improving vehicle engine performances.

"We are proud that all grades of Marathon gasoline with STP additives are Top Tier certified throughout our 19-state marketing area," said Bill McCleave, Marathon's director of brand marketing. "Marathon gasoline continues to provide our customers the assurance of quality associated with the STP brand and will remove the accumulation of harmful deposits and improve the performance of their vehicle's engine." 

Independent laboratory testing by the American Automobile Association shows that Top Tier certified gasoline keeps engines significantly cleaner than non-Top Tier brands.

"For over 10 years, we've been proud to have our proprietary STP additives in Marathon gasoline," said Guy Andrysick, senior vice president and general manager of the Global Auto Care Division of Spectrum Brands Holdings, the owners of the STP brand. "The continued combination of these two long-time, trusted American brands creates an offering that's both unique and unmatched in the industry."

Findlay-based Marathon Petroleum is the nation's third-largest refiner, with a crude oil refining capacity of approximately 1.8 million barrels per calendar day in its seven-refinery system. Marathon brand gasoline is sold through approximately 5,400 independently owned retail outlets across 19 states. Through subsidiaries, Marathon Petroleum owns the general partner of MPLX LP, a midstream master limited partnership.
