Finding cheap gas in Trenton (08691)
Robbinsville and the eastern edge of Hamilton make up this ZIP, an exurban part of Mercer County that markets itself as a highway crossroads roughly halfway between New York City and Philadelphia. Interstate 195 and the Route 130 and Route 33 corridors give the area strong access in every direction, and a lot of newer development has followed.
New Jersey's attendant-pump law means full-service fuel everywhere, and the state's low gas tax keeps prices reasonable for the densely populated Northeast. The stations near the I-195 interchange and along Route 130 catch both commuters and long-haul travelers, and those high-volume stops usually post the keenest prices.
With warehouses, distribution centers, and new neighborhoods filling in around the highways here, demand stays firm and competition is real. The truck traffic off I-195 and the Turnpike feeds the busier travel-oriented stops. Comparing the I-195 and Route 130 corridor stations is the reliable way to land a cheaper fill in this part of the township.

How to save more on gas in Trenton
1. Use warehouse clubs
Costco and Sam’s Club typically price 15-25 cents per gallon below nearby stations. Membership pays for itself within a few fill-ups.
2. Fill up early in the week
Stations often raise prices Thursday for weekend demand. Fill up Monday through Wednesday to avoid the lift.
3. Keep tires properly inflated
Properly inflated tires improve fuel economy by up to 3 percent at current prices. Check pressure once a month.
4. Check back tomorrow
Prices can shift 10-20 cents overnight during volatile markets. A quick check before you leave home avoids paying yesterday’s spike.
5. Pay cash at split-pricing stations
Stations with cash and credit split pricing typically save an average of 10 cents per gallon when you pay cash.

About gas prices in New Jersey
New Jersey's gas tax was around 42 cents per gallon as of recent updates, having risen significantly since 2016 to fund the Transportation Trust Fund. The state operates several refineries (Bayway, Linden, Phillips 66) which historically meant cheaper prices, but recent refinery closures have shifted the balance toward pipeline and tanker imports. New Jersey is also one of two states (Oregon being the other) where self-service is restricted, which adds a small per-gallon labor cost. Costco, Sam's Club, BJ's Wholesale, Wawa, and QuickChek lead on value.
