BP has notified the media that some gasoline it produced at its Whiting, Indiana refinery since August 13 may be contaminated and lead to poor performance, hard starting, stalling, or other related issues.

According to the AP, BP is alerting northwestern Indiana fuel distributors that it's recalling unleaded regular gasoline shipped from its Whiting fuel storage terminal Aug. 13-17.

The company said Monday it believes that fuel stored in a tank at the storage depot could cause hard starting, stalling and other drivability issues. BP asks any customer whose vehicle has experienced those problems since Aug. 13 to contact its customer hotline at 800-333-3991.

BP says the fuel may have been purchased by motorists at BP and other retail outlets in the region.

BP says it's going through shipping records and contacting customers who may have loaded tanker trucks at the terminal during the affected period.

The Times of Northwest Indiana reports that the company says it has received complaints about fuel sold at BP, Luke Oil and Thornton's stations in the Chicago area in the last seven days.
