Fuel sold without a major oil company’s name or mark.
Unbranded fuel is the same base product as branded fuel, just without a major’s additive package and name. It usually costs a little less, which is the main reason to run it.
The old belief that unbranded meant lower quality has not been true for a long time. It meets the same standards and runs in any engine. Plenty of large, well-run convenience chains sell unbranded on purpose and keep the savings.
Some independents have grown big enough to blend their own additive and build a brand of their own, doing exactly what the majors do. To the refiner that supplies them, that fuel still leaves as an unbranded sale.
In useThe chain runs unbranded at clean, modern sites and puts the few cents a gallon it saves into a sharper pump price.
Where the word comes from
Unbranded is just branded with un in front, meaning not. It marks fuel that carries no major’s name.
