(MCT) — Contaminated gasoline from a BP refinery has so far led to about 6,500 claims from motorists trying to recoup hundreds of dollars they spent for car repairs, a spokesman said Monday.

The company, which has fielded about 19,000 inquiries from motorists, last week recalled 2.1 million gallons of gasoline from its refinery in Whiting, Ind. The bad gas affected service stations in three states, including the Chicago region of Illinois, Indiana and Wisconsin. Since then, BP has checked its entire distribution system, BP spokesman Scott Dean said.
