TOP TIER™ Licensing Program

TOP TIER Program

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.
