New Jersey gas prices
New Jersey gas prices are near the national average, which is surprisingly affordable for the Northeast. The state has lower gas taxes than New York, Connecticut, and Pennsylvania, which helps. New Jersey also sits right next to major refinery infrastructure in the Delaware Valley, keeping supply chains short.
New Jersey was famously one of the last states to ban self-serve gas (Oregon recently relaxed its ban). Full-service gas hasn't significantly raised prices because the state's other cost advantages offset the labor cost. Drivers from New York and Pennsylvania regularly fill up in New Jersey when passing through the Turnpike or Garden State Parkway.
Price history
Why is New Jersey gas cheaper than New York and Pennsylvania?
Lower gas taxes are the biggest factor. New Jersey's fuel taxes are substantially below both New York and Pennsylvania. Proximity to Delaware Valley refineries also keeps supply costs low.
Does full-service gas make New Jersey gas more expensive?
Surprisingly, no. New Jersey has required full-service pumping for decades, but lower taxes and good refinery access offset the labor cost. New Jersey gas is still cheaper than most neighboring states.
Does New Jersey have refineries?
New Jersey has had refineries historically, though some have closed in recent years. The state still benefits from proximity to the Philadelphia-area refinery complex just across the Delaware River, which is one of the largest refining hubs on the East Coast.
