New Jersey Gas Prices and Why They Are What They Are
Prices as of July 06, 2026, per AAA · Updated July 06, 2026
As of July 06, 2026, regular gasoline in New Jersey averages $3.82/gallon (the 21st-highest in the U.S.), per AAA — 0.01 below the national average of $3.83. Diesel averages $4.86. State fuel taxes and fees add 45.0¢/gallon on top of the 18.4¢ federal excise.
Where the $3.82 goes
| Component | $/gallon | Share | Source |
|---|---|---|---|
| Crude oil (national cost, WTI June 2026) | 2.04 | 53% | EIA |
| Federal + New Jersey fuel taxes (18.4¢ + 45.0¢) | 0.63 | 17% | Tax Foundation |
| Refining, distribution, margins & embedded program costs (residual) | 1.15 | 30% | computed |
Crude oil costs every state's refiners roughly the same, so New Jersey's position comes from the tax line and the residual: refining capacity and logistics, fuel-specification requirements, and any carbon or clean-fuel program costs embedded in the pump price.
