Where to find cheap gas in Riverhead for Memorial Day weekend

Looking to fill up your gas tank before a long drive out of town this holiday weekend?
You might want to stop at the Valero gas station on Main Road in Jamesport, which at $3.93 a gallon for regular gas, had the cheapest price in town Thursday, according to www.Longislandgasprices.com.
(Update: That price had fallen to $3.91 Friday, see photo.)
And at $3.95 a gallon, the Valero gas station on Peconic Avenue in Riverside had the lowest price for regular gas in the 11901 zip code Thursday.
It also had the lowest price for mid-grade and premium gasoline at $4.03 and $4.11.
Those prices are lower than the Long Island average of $4.085 for regular gas, though still 15 cents more than the national average of $3.808. Just be sure to hit the ATM or get cash back from the supermarket before filling up; the stations charge extra for credit.
One man from Mastic said he had waited until running an errand on the North Fork to fill up his tank in Jamesport. He said the price was four cents lower than in his hometown.
“I just saved 40 cents,” he said as a gas attendant pumped 10 gallons into his van. “”It adds up at the end of the year.”
The U.S. average is down nine cents from this time last week, but way up from last year’s price of $2.771 for regular gas, according to the AAA Daily Fuel Gauge report.
“Traditionally, prices tend to drop right before Memorial Day,” said Fred Rozell, director of retail pricing for Oil Price Information Service. “In the next 30 days you can expect to see price go down slightly because the wholesale prices are decreasing.”
The Citgo on West Main Street and the Shell at the Riverside traffic circle were tied for second lowest in 11901 at $3.97 per gallon for regular gas Thursday.
The lowest fuel price in all of Long Island was at Gas Sale in Central Islip at $3.88 for regular gas.
