New Jersey Fuel Prices: What You Actually Pay at the Pump

New Jersey's average retail prices currently sit at $3.877 for regular gasoline, $4.497 for mid-grade, $4.779 for premium, and $4.931 for diesel. That regular figure runs almost exactly in line with the US national average of $3.867, putting the Garden State squarely in the middle of the national pack rather than at either extreme.

These numbers reflect pump prices across roughly 11 metro areas and corridors in the state, from the Newark–Jersey City sprawl to the Trenton and Atlantic City markets. Because prices are quoted in US dollars per gallon, there's no currency conversion to worry about here, but the spreads between grades tell their own story.

What Drives New Jersey's Gas Prices

Three forces dominate what a New Jersey driver pays: federal and state fuel taxes, the cost of refined product on the wholesale market, and the state's unusual full-service pumping law.

The federal excise tax adds 18.4 cents per gallon on gasoline and 24.4 cents on diesel everywhere in the country. On top of that, New Jersey layers its own motor fuels tax plus a Petroleum Products Gross Receipts Tax (PPGRT). The PPGRT is the key quirk: by law it adjusts annually so that fuel-tax revenue hits a fixed target for the Transportation Trust Fund. When consumption falls, the per-gallon rate is pushed up to compensate, which means New Jersey's combined state tax has climbed steadily and now ranks among the higher state burdens in the Northeast. That tax engineering is a big reason regular sits near the national average despite the state's proximity to refining capacity.

New Jersey is a major fuel importer in the sense that it consumes far more refined product than it makes, but it sits next to one of the densest refining and pipeline clusters in the country. The Colonial Pipeline terminus, Linden-area terminals, and New York Harbor benchmark pricing all feed the local market, which usually keeps wholesale supply ample and prices less volatile than landlocked states that depend on a single pipeline.

The state's famous ban on self-service gasoline also matters. Every gallon of regular and mid-grade is pumped by an attendant, and that labor cost is baked into the retail margin. It rarely shows up as a dramatic surcharge, but it's part of why New Jersey doesn't undercut its neighbors as much as its tax structure alone might suggest. (Diesel and, at many stations, premium are exempt from the self-serve ban.)

How New Jersey Compares

Regional context helps. Drivers near the state line often compare New Jersey with cheaper inland markets like Ohio or New Mexico, where lower taxes and shorter supply chains can shave double-digit cents off a gallon. To the north, neighbors such as New Hampshire and Maine carry their own New England tax and logistics profiles that push their averages in different directions. The wide premium-to-regular gap in New Jersey — about 90 cents — is typical of high-tax coastal markets where octane carries a steep step-up.

Diesel at $4.931 is notably higher than gasoline, reflecting both the larger federal excise on diesel and persistent freight demand. For commuters and fleets alike, that gap is worth tracking, because diesel tends to move on industrial-demand cycles that don't always follow the gasoline curve.
