TOP TIER™ Detergent Gasoline Brands
  • All retail locations within the licensed country must meet the high standards of the TOP TIER™ program.
  • All gasoline grades must be treated with an approved TOP TIER™ Detergent Gasoline additive at the correct concentration.
  • The TOP TIER™ logo must be prominently displayed. 
  • TOP TIER™ licensed retailers agree to not use organometallic additives (such as MMT or Ferrocine).
  • Find more information here.

We are navigating through unprecedented times.  Disastrous weather conditions and unplanned additive production operational outages have resulted in some of our TOP TIER™ Detergent Gasoline Fuel Marketers being unable to supply gasoline with the approved detergent at the approved dosage.  The TOP TIER™ program is committed to working with its participants and the industry in managing through this in the best way possible and to return to supplying gasoline fully meeting the TOP TIER requirements as soon as possible.

As this shortage is expected to last through the end of the year, you may see some gas stations noting they are unable to supply TOP TIER™ Gasoline at this time.  The brand will still be listed on as this will not apply to all stations.

The TOP TIER™ Detergent Gasoline program, its Automotive OEM Sponsors and its Fuel Marketers remain committed to gasoline quality, minimizing the impact of the shortage and returning to providing gasoline that meets the TOP TIER™ requirements as soon as possible.
