Premium gas prices rise: higher octane, bigger profits, and marketing myths
Premium gasoline now costs roughly $1 more per gallon than regular in many areas, with CNN noting the gap has widened from about 20 cents over decades to near $1 today, while demand climbs as more new cars require or recommend higher-octane fuel. The rise is partly due to higher refining costs and ethanol additives, which pump up wholesale-to-retail margins for stations. Cars that don’t need premium typically see no performance benefit from higher octane, according to AAA and industry analysts, yet marketing and perceptions of “better performance” keep shoppers paying the premium. Premium gas accounted for about 13% of sales last year, and the price spike persists even as drivers continue to fill up, illustrating a blend of cost, demand, and marketing factors behind the price puzzle.
