 TOP TIER Diesel


FS FAST STOP locations are among the first to become registered TOP TIERTM Diesel Fuel sites. The TOP TIER Diesel Fuel program was developed by a group of leading diesel equipment manufacturers. They recognized the benefits of additized diesel fuel in their engines. The TOP TIER program, originally launched in 2004, focused on gasoline standards before introducing a diesel fuel standard this September. FAST STOP locations featuring Dieselex® Gold are among the first retailers to earn the new certification.

"We strive​ to provide the best fuel standard in the industry by not only meeting, but exceeding, the new TOP TIER Diesel Fuel standards,” said Curt Dunafin, GROWMARK​ energy services manager. “Additional performance benefits of Dieslex Gold include: cleaning up dirty engines, controlling moisture, faster starts, lower emissions, and extending storage stability.”

For over 65 years, FS Dieselex Gold has been maximizing engine efficiency, restoring lost power, and protecting tanks and fuel system components
