Hundreds of gasoline cars may have been mistakenly fueled with diesel after a Couche-Tard station in New Brunswick, Canada, recently put thousands of liters into the wrong filling tank.

The number of cars that were filled up with diesel by accident isn't known, but the Canadian gas station is making good on the error, Jalopnik reported via Canada's AutoGo.

According to Infodimanche, at least 300 cars were affected by the fuel mix-up.

"My garage bill amounted to nearly $700," one customer told Infodimanche, while another driver is facing a much steeper bill of $4,000, along with being affected for a week's work.

The gas station, which is a popular one due to its location, is taking full responsibility for the mistake.

"Firstly, we wish to indicate that the reservoirs of the service station were drained early Friday morning [Jan. 31]," Couche-Tard spokesperson Mélissa Lessard told Infodimanche in a translated interview. "Customers can return [to refill] without any worry.

"Regarding claims, customers who have been affected by this incident have only to bring our store to purchase their fuel bill and all other bills related inconvenience," Lessard said. "They must submit these documents to our on-site manager, who will follow up with our office. Compensation will be forwarded directly to customers by mail."

Couche-Tard will reimburse affected motorists for expenses including repair costs and towing charges, as well as the costs of car rental if they apply.

When a traditional gasoline-powered car is filled with diesel fuel, the engine can misfire as black smoke forms under the hood, according to AutoGo. Tanks mistakenly fueled with diesel should be emptied as quickly as possible to avoid more serious mechanical issues.
