What is the difference between branded and unbranded fuel?
Branded fuel is sold under a refiner’s or marketer’s brand and bought through a supply agreement; unbranded fuel carries no brand and is bought at the unbranded rack or on the spot market. The molecules can come off the same terminal. What differs is the brand’s additive package and, above all, the contract wrapped around them.
If you are a station owner or fleet buyer, the choice is which supply model you want to be locked into, and what happens to you when supply is short.
What does a branded supply agreement buy you?
A branded agreement buys a supplier’s commitment to keep you supplied, in exchange for your commitment to buy that brand. A 2015 NPR story on independent stations put it this way: “When a gas station is in a branded contract, it needs to buy that brand of gas.” It also quoted a fuel distributor: suppliers “protect that product before product that’s not under a contract,” and “that supply agreement comes in handy when product gets tight.” (NPR/KUNC, 2015)
The second quote is the part that matters in a shortage. When a terminal cuts what each buyer can lift, fuel allocation decides who gets product first, and contract volume usually comes before open-market volume. For how that plays out at the rack, see fuel allocation and terminal limits.
You pay for that priority through the price, through the brand’s requirements, and through the length of the commitment. Terms vary by supplier and by deal, so read the actual agreement rather than a rule of thumb.
What does unbranded fuel buy you?
Unbranded fuel buys flexibility on price and source. The same NPR piece described an unbranded station that gets its gas from a fuel distributor, a jobber, and said that “when it’s unbranded, it basically buys it on the spot market, taking advantage of that day’s lowest prices.” (NPR/KUNC, 2015)
You can shop between suppliers and terminals, and you are not tied to one brand’s rack pricing. If you want a refresher on either term, the short versions are at what is a jobber and what is rack pricing.
The cost of that freedom is the other half of the quote above: when product gets tight, unbranded volume is the volume suppliers protect last.
Is unbranded fuel common?
Yes, and it has been growing. OPIS, a fuel price reporting service, reports that branded outlets led about 55% to 45% in January 2018, and that unbranded passed branded in June 2019, topping 52% share. (OPIS) Those figures are for gasoline retail outlets; they do not tell you what share of diesel or fleet fuel is bought each way.
How do the contract terms compare?
Compare the two models on what you commit to and what you are exposed to, as well as price per gallon.
| Term | Branded | Unbranded |
|---|---|---|
| Who you buy from | The brand’s supplier or its authorized distributor | Any supplier or terminal you can get approved at |
| Volume commitment | Typically a minimum, set in the agreement | Usually none, or set per load or per deal |
| Priced off | The brand’s rack, plus whatever the agreement adds | The unbranded rack or a spot quote |
| In a shortage | Contract volume is typically served first | You compete for what is left |
| Switching suppliers | Constrained by the agreement | Open, subject to credit and terminal approval |
| Brand requirements | Signage, image and product standards may apply | None |
| Walking away | Read the exit and franchise terms before signing | Usually little, but check any term or credit agreement |
Each cell is a question to put to a supplier, not a promised term. Contract length, minimums and penalties are negotiated, and none of them are the same twice.
One legal note for station owners: branded relationships can fall under franchise law, the federal Petroleum Marketing Practices Act, which limits how a supplier can end or decline to renew a franchise. Check the statute and your own agreement with counsel; this post is not legal advice.
What does the difference look like on a real order?
Say you buy 8,000 gallons, and the numbers below are hypothetical, not market data. Suppose the unbranded rack at your terminal is $2.80 a gallon and your branded supplier prices the same load at $2.86 under its agreement. On 8,000 gallons the branded load costs $480 more (6 cents x 8,000).
The shortage is where the cost hides. Say the terminal is limited and the brand’s contract buyers lift their full volume while open-market buyers get half. Your unbranded load of 8,000 becomes 4,000, and you either wait, haul from a second terminal, or pay a spot premium for the rest. Whether the 6 cents a gallon was worth paying depends on how often that happens to you and what a dry tank costs.

Which one fits you?
Branded fits when running out is expensive and you want a supplier obligated to you: a retail site that depends on a brand, a high-throughput location, or a site with no easy second terminal. You accept the premium and the commitment as the price of that obligation.
Unbranded fits when you can tolerate an occasional scramble and you value being able to move volume to whoever is cheapest this week: fleets with storage, multiple sites, or a second supplier already approved.
Many buyers split it, holding a branded agreement for core volume and buying unbranded for the rest. Whatever you pick, ask each supplier three things in writing: what you must buy, what you are supplied when the terminal is on allocation, and what it costs to leave.
