A batch of bad gasoline being sold from a station is causing headaches for motorists in the Toronto area, and there is concern the problem could get worse.

Gas sold at the Mississauga Esso station, located at Glen Erin Drive and the Collegeway, has been blamed for seizing up engines.

For Charles Bates, who also filled up at the station, the speculation will do little to ease a hefty repair bill for his car.

"The ignition would turn over, but would die almost instantly," he said, adding that the car would stay running for only a few seconds.

Luca Kulesza also fueled up at the station, and $20 worth of gas cost him $620 in repairs.

The Calgary-based wholesale company that supplies the station has confirmed that the fuel is tainted.

Tom McMillan, from the Parkland Fuel Corporation, said that drivers are complaining that their vehicles aren't starting properly.

It's believed that bad fuel was sold from over the weekend until Monday at about 1:30 p.m. at the Esso, which is an independently owned and operated station.

The station has insurance and is now recording claims and taking fuel samples, McMillan said.

McMillan added that the fuel was delivered clean and was likely contaminated at the station.

It's not clear what caused the contamination, but MacMillan speculated that it may be from melted snow.

Drivers who may have fueled up with the bad gasoline can call Esso customer service at 1-800-567-3776.
