How Phillips 66 fuel pricing works
Phillips 66 operates a vertically integrated refining and marketing business. The company refines crude oil at 13 refineries in the US and Europe (including the recent full acquisition of Borger and Wood River refineries effective January 1, 2026), then markets the finished fuel through three branded networks: Phillips 66 (primarily Midwest and Mountain West), 76 (primarily West Coast and California), and Conoco (primarily Midwest, Mountain West, and Southwest). The combined network includes approximately 7,500 sites. Most are independently owned and operated, with Phillips 66 supplying fuel and licensing the brand. Pump pricing at each station reflects local wholesale rack price, state and local taxes, and competitive positioning.
Phillips 66 corporate story
Phillips 66 Company was created in 2012 when ConocoPhillips spun off its refining, marketing, and midstream business into a separate publicly traded company. Headquartered in Westchase, Houston, Texas, Phillips 66 trades on NYSE under ticker PSX. The company retained the Phillips 66, 76, Conoco, and JET retail brands at the spinoff, and has since expanded retail brand licensing into upper Midwest and Northeast states (Connecticut, Delaware, Kentucky, Maryland, Massachusetts, Maine, Michigan, Minnesota, New Hampshire, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, and Wisconsin) starting in 2024.
Top Tier status and PROclean fuel
Phillips 66, 76, and Conoco brands market their gasoline under the PROclean banner, which is on the Top Tier Detergent Gasoline brands list since October 2004. Top Tier is a standard endorsed by major automakers (BMW, GM, Toyota, Honda, Ford, Audi, Volkswagen, Mercedes-Benz, and others) requiring detergent additive levels above EPA minimums. All three Phillips 66 brand families meet the Top Tier specification, so drivers at any Phillips 66, 76, or Conoco station get the PROclean additive package.
Phillips 66 vs Conoco vs 76
All three brands are owned by Phillips 66 Company and all carry PROclean Top Tier fuel, so the underlying fuel product is consistent. The brands differ by geography and history: 76 is the West Coast and California legacy brand (originally Union 76, oldest of the three), Phillips 66 is the Midwest and Mountain West heritage brand, and Conoco is the Midwest and Southwest brand inherited from the 2012 ConocoPhillips spinoff. As of recent brand-licensing expansions, Conoco is becoming the primary brand for the new East Coast market entries while Phillips 66 anchors the Midwest. Drivers won't notice meaningful fuel-quality differences between the three.
