As of May 9, 2026, New Jersey’s average gas price sits at $4.54 per gallon for regular unleaded gasoline, marking another significant jump at the pump that signals no relief is coming soon. This represents a concerning week-over-week increase of $0.34—roughly 8 percent—from the previous week’s $4.27 average, putting pressure on commuters and consumers across the state just as summer driving season approaches. The numbers tell a sobering story: at select stations near Newark airport and other locations throughout New Jersey, prices have already crossed the $5.00 per gallon threshold.
For a driver filling up a 15-gallon tank at these premium locations, a single fill-up now costs more than $75, a reality that has become routine at many service stations across the state. What’s particularly striking is the year-over-year comparison. Gas prices in New Jersey are now $1.41 higher than they were in May 2025—a dramatic 50 percent increase in just twelve months. This sustained climb reflects a combination of state policy, seasonal fuel changes, and global market dynamics that show no signs of reversing quickly.

What Are New Jersey Gas Prices This Week?
New Jersey’s pump prices as of May 9, 2026, continue to exceed the national average, which sits at $4.55 per gallon. However, the state average of $4.54 masks significant variation across different locations and fuel grades. While some budget-conscious stations still hover in the $4.30 to $4.40 range, premium locations—particularly those near major transportation hubs—routinely charge above $5.00. The weekly price surge of $0.34 represents one of the sharpest single-week increases New Jersey has experienced in recent months.
This acceleration occurred between May 4 and May 9, suggesting that market pressures are intensifying rather than stabilizing. Motorists who fueled up early in the week likely paid roughly 8 percent less than those who waited until Friday. To put this in practical terms: a New Jersey commuter who drives a fuel-efficient sedan with a 13-gallon tank and fills up twice weekly is now spending roughly $118 per week on gasoline, compared to approximately $111 just seven days earlier. For a household with multiple vehicles, these weekly increases compound into significant monthly expenses.
Why Gas Prices Jumped $0.34 in One Week
The rapid acceleration in New Jersey gas prices reflects several converging factors. Crude oil prices on global markets have been volatile, driven by geopolitical tensions and production concerns in key supply regions. Refineries operating at higher capacity to meet spring demand have also pushed wholesale costs upward, which gas station owners pass directly to consumers. One critical limitation of week-to-week price analysis is that it captures short-term volatility rather than sustained trends.
A $0.34 jump in one week could be followed by modest declines, or it could signal the beginning of a sharper climb. Gas prices are notoriously sensitive to expectations about future supply and demand, meaning traders’ fears about supply disruptions can drive prices up faster than actual physical shortages would warrant. The seasonal switch to summer-blend gasoline, which began in early May across New Jersey and the broader Northeast, adds an additional 2 to 3 cents per gallon to retail prices. This seasonal formulation is required by the U.S. Environmental Protection Agency to reduce smog-forming emissions during warmer months, but it comes at a direct cost to consumers who see little benefit at the pump.
How New Jersey’s Gas Tax Drives Pump Prices Higher
New Jersey’s state gasoline tax stands at 49.1 cents per gallon as of January 1, 2026—one of the highest in the nation. This represents an increase of 4.2 cents from the prior year and reflects a 2024 law that schedules automatic tax increases through 2029. Unlike many states that have frozen their gas taxes to protect consumers from price volatility, New Jersey’s automatic increase mechanism ensures that prices will continue climbing regardless of what happens in global oil markets. The state tax alone now accounts for roughly 11 percent of every gallon purchased at New Jersey pumps.
This means that even if crude oil prices fell by 20 percent, New Jersey motorists would still pay significantly more than consumers in neighboring states like Pennsylvania (where the gas tax is 58.7 cents but has been frozen) or Delaware (30.1 cents, also frozen). The scheduled tax increases through 2029 represent a hidden but inevitable price hike that will compound over time. For context, New Jersey’s automatic gas tax escalation generates substantial revenue for the state’s Transportation Trust Fund, which is supposed to finance infrastructure repairs and transit improvements. However, this revenue mechanism inverts the usual consumer expectation: in most states, falling oil prices provide relief at the pump, but in New Jersey, the state tax ensures that baseline costs remain elevated while the state collects more revenue as consumption shifts in response to higher prices.
The Impact of Summer Fuel Switching and Global Markets
The transition to summer-blend gasoline in early May locks in higher prices through the fall. Refineries that produce this cleaner-burning fuel have less flexibility to optimize production, and the additional processing costs directly translate to higher prices at the pump. New Jersey drivers will experience this seasonal surcharge for the next five months, with no option to avoid it or seek alternatives. Global oil market conditions remain a wildcard.
Geopolitical tensions in key producing regions, production cuts by major exporters, and expectations about future demand all influence the barrel price that New Jersey refineries pay. While the Trump administration’s stated focus on increased domestic oil production could theoretically ease prices over the next few years, the current global market remains tight, and any disruption in overseas supply quickly ripples through to New Jersey gas pumps. The comparison with national averages is instructive: at $4.54 per gallon, New Jersey sits just slightly below the national average of $4.55, despite having the nation’s fourth-highest state gasoline tax. This suggests that crude oil prices and refinery costs are currently the dominant driver of prices, but New Jersey’s tax structure ensures that the state floor for gas prices remains firmly above what other, less-taxed states experience.
The Warning About Future Price Escalation
One critical limitation in relying on AAA data or other real-time price sources is that they reflect current conditions, not future trends. Seasonal dynamics, refinery maintenance schedules, and global supply decisions can shift prices dramatically in a matter of days. Motorists who assume current prices are “locked in” often face surprises when prices jump ahead of their expectations. The scheduled increases to New Jersey’s gas tax through 2029 represent a particularly troubling long-term warning.
Unless the law is repealed—which appears unlikely given legislative priorities—motorists can expect the state’s contribution to pump prices to grow by roughly 0.6 cents per gallon annually. Combined with the inherent volatility in crude oil markets, this structural increase means that New Jersey drivers should not expect meaningful price relief even if global conditions improve. Another limitation worth noting is that reported state averages can mask dramatic variation between regions. A station in rural northwest New Jersey might price significantly lower than a station near the New Jersey Turnpike, where location and convenience commands a premium. Savvy motorists who monitor prices across multiple stations can save 10 to 20 cents per gallon, but this requires effort and local knowledge that not all drivers possess.
Where to Find the Cheapest Gas in New Jersey
Real-time price data from AAA’s fuel price tracker and GasBuddy allow motorists to identify the cheapest stations in their immediate vicinity. Warehouse clubs like Costco and Sam’s Club often undercut traditional gas stations by 10 to 15 cents per gallon, though membership fees and geographic location limit their utility for many drivers. A motorist who fills up twice weekly could save roughly $30 to $45 per month by shopping strategically.
Station location matters enormously. Stations near highway exits typically charge 15 to 30 cents more than off-highway competitors, reflecting the convenience premium. Similarly, premium fuel at any station typically costs 30 to 50 cents more per gallon than regular unleaded, a premium that manufacturers rarely justify and that most drivers can safely avoid unless their vehicle’s manual specifically recommends premium fuel.
What’s Ahead for Gas Prices in the Coming Weeks
The outlook for June and July remains uncertain. Summer driving season typically pushes demand higher, and if global oil supplies tighten further, New Jersey prices could approach or exceed $4.75 per gallon within the next four to six weeks.
Conversely, if crude oil production increases or geopolitical tensions ease, drivers might see modest relief—but any decline will be limited by the state’s elevated gas tax and the summer-blend fuel requirement. The longer-term trajectory through 2026 depends heavily on factors outside New Jersey’s control: global crude oil production decisions, refinery utilization rates, and international supply disruptions. What remains certain is that the state’s legislated gas tax increases will provide a structural floor beneath any potential price declines, ensuring that New Jersey drivers will continue paying among the nation’s highest pump prices regardless of external conditions.
Conclusion
New Jersey’s gas prices at $4.54 per gallon as of May 9, 2026, reflect a volatile market pushing upward at an alarming pace. The $0.34 weekly jump and $1.41 year-over-year increase demonstrate that relief remains elusive for motorists already feeling the strain on household budgets.
Understanding the interplay between global crude oil markets, state gasoline taxes, and seasonal fuel formulations can help drivers make more informed purchasing decisions, but it cannot shield them from the underlying cost dynamics. Moving forward, New Jersey drivers should monitor AAA’s real-time price data, consider shifting fuel purchases toward off-peak hours and lower-priced stations, and prepare for the likelihood that summer prices will remain elevated. The state’s automatic gas tax escalations through 2029 ensure that even optimistic scenarios about global oil production will provide limited relief at the pump.
