Roughly 50–70 cents of every gallon sold on Long Island is federal, New York State, and county tax — among the highest combined fuel-tax burdens in the country. Add the downstate cost of real estate, delivery logistics for an island with no refinery, and the required reformulated summer blend, and Long Island consistently prices 30–50 cents above the national average.

Usually, yes — warehouse-club gas is reliably near the bottom of the price table. Right now BJ's in Riverhead is at $3.81/gal, which saves about $3.30 per 15-gallon fill versus the island average. If you already hold a membership and pass one on your commute, it is the most consistent saving available.
