As the average price of a gallon of regular gasoline in New York City hit a record $4.20 on Wednesday, the State Bureau of Weights and Measures gave station owners like Mr. Staiano the official go-ahead to charge by the half-gallon, provided they can prove that they have ordered new pump computers that can handle prices up to $9.99 a gallon. The new computers cost about $400 each, not including installation fees; Mr. Staiano said his would arrive in about a month.
Experts estimate that as many as 500 stations across the state, most of them independently owned, have older pumps that are unable to go above $3.99. A handful of such stations are sprinkled around the city and suburbs, including a Getty pump on Kings Highway in Brooklyn and another on Broadway in the Bronx, according to Newyorkgasprices.com. Other stations are on Long Island in Cedarhurst, Elmont and Hewlett.
By the end of the business day on Wednesday, the state had received 40 applications from stations wanting to charge for gasoline in half-gallon increments. There is a backlog of up to 17 weeks for the replacement machines from various companies, so state officials expect half-gallon pricing to be around for about five months.
There was little rush to get the new pumps until a few months ago, when gasoline prices kept climbing. As prices blew past $4 this month, stations with older pumps turned into bargains overnight for drivers lucky enough to spot them.
Of course, what the drivers saved, the owners lost. Mr. Staiano said his profits were trimmed by 6 cents to 8 cents a gallon when the pumps were stuck at $3.99 (and 9/10). That is why he began charging by the half-gallon a couple of days ago, when, he said, state officials told him an approval was imminent.
The state previously let stations charge by the half-gallon in the fall of 2005, when gas prices passed $2.99, but only for 90 days. This time, prices have risen so high so quickly that the manufacturers of the replacement parts have been unable to keep up. Mr. Staiano has sent a $1,000 deposit for his new pump computers to U.S. Petroleum Equipment in Combined Locks, Wis.
The gauges in the older gas pumps are computers but look more like the innards of an old adding machine or cuckoo clock. Gears of different sizes spin at different speeds depending on the digits they represent. Station attendants flick tabs to change the digits, which are written on hard black rubber spools. The digit representing $2 on one of Mr. Staiano’s pumps was written in what looked like white-out.
Mr. Staiano called his older pumps, which were bought in the 1980s, “war horses” because they rarely break or lose their calibration. New digital pumps that accept credit cards and sell multiple brands of fuel can cost as much as $15,000 each. But because 80 percent of his customers pay cash, Mr. Staiano said, the investment is not worth it.
The higher gas prices go, the more often stations have to repair pump computers, according to Robert Renkes, the executive vice president of the Petroleum Equipment Institute, a trade group in Tulsa, Okla., that represents manufacturers of station equipment.
For now, Mr. Staiano has placed yellow tape on his pumps alerting customers that the prices are for half-gallons. He also tells them when they first pull in that the price on the meter would be doubled.
Customers using credit cards on Wednesday paid $4.15 a gallon, lower than at many stations in the area. Those using cash paid $4.05, since Mr. Staiano did not have to turn over 2 percent or more to the credit-card companies.
