Sulfur Shuts 500 Shell, Texaco Stations
NEW ORLEANS - Just before the heavy-driving Memorial Day weekend, more than 500 Shell and Texaco stations in the South have stopped selling gasoline because of high sulfur levels that can ruin vehicle fuel gauges and make an empty tank appear full.
The damage done by the bad gasoline could cause some drivers to run out of gas unexpectedly. Also, car owners may have to replace their fuel gauges ? a repair job that can easily cost $400 to $600.
The tainted gasoline originated at the Motiva Enterprises refinery in Norco, La., according to Shell Oil Co. Motiva is the refining arm of Shell in the East and South. Motiva supplied the gasoline to both Shell and Texaco.
The refinery said it is investigating how the high sulfur levels occurred. Sulfur is naturally present in crude oil; some of it is supposed to be removed during refining.
As of Friday, 119 Shell and Texaco stations were closed in the New Orleans area, and 400 were not selling fuel in Florida, said Shell spokeswoman Helen Bow.
The problem occurred at an especially bad time for gasoline stations, which had been expecting brisk sales, at high prices, ahead of the holiday weekend.
"The pumps have been off since Wednesday," said Sri Guntaka, a cashier at a Shell station in New Orleans. "We've lost a lot of customers, hundreds of them. It's very bad."
Gas tanks have a float ball that rises and falls with the fuel level. An electrical system reads the float ball's level and transmits the information to the dashboard fuel gauge. The system uses silver electrical contacts, which can be quickly corroded by sulfur.
The problem came to light this week after drivers began complaining about inaccurate fuel gauge readings.
Besides the New Orleans area, problem fuel turned up in shipments to Miami, Tampa, Sarasota and Fort Lauderdale, Shell said.
Shell is replacing the gasoline at its stations. But Bow did not have an estimate of when all the stations would be pumping again.
Shell said it had received 1,800 queries and 825 claims from people who said their fuel gauges had been affected.
