Two QuikTrip stores in Olathe mistakenly sold gasoline mixed with diesel fuel Thursday, causing car problems for an unknown number of customers.
Mike Thornbrugh, a spokesman for the convenience store chain based in Tulsa, Okla., said the stores affected were at South Blackfoot Drive and East Santa Fe Street and at 157th Street and U.S. 169.
He said the mixup occurred at the fuel terminal, and tankers delivered the bad product to the stores.
The contaminated fuel was removed, and both stores resumed selling gasoline later Thursday.
Thornbrugh said the mixture of fuel can cause vehicles not to operate properly.
He said the chain will pay for towing services, repairs and rental cars for affected customers. In addition, they will be reimbursed for their gas purchase and given a free tankful.
Affected customers should call the QuikTrip Kansas City office at913-362-3700.
