Tier-3 Gas Stations

Brands and locations identified here represent gas retailers in Utah that purchase and distribute gasoline from refineries who meet federal Tier 3 standards locally by producing gas which contains 10 ppm sulfur or less on an annual average basis (rather than by purchasing sulfur credits or through corporate pooling averages).

Tier 3 gasoline is cleaner, contains less sulfur, and creates less harmful air pollution than non-Tier 3 gas, especially when used by vehicles produced after 2017. Tier 3 compliance considers the average sulfur content of gasoline produced by refineries over the course of a year - and thus the sulfur content of any particular gallon of gasoline dispensed at a gas station cannot be guaranteed.

Notice a station of one of these Tier 3 retailer brands near you that isn't on our map? Let us know at tier3utah@gmail.com!
