MANCHESTER, Mo. – A south St. Louis County man said his car started having serious problems after he got gas at the Manchester Costco. Now, Costco is sending out a warning to drivers who filled up their tank at their Manchester location on Friday.

Staff said the fuel that was put in their unleaded tanks is to blame for the issues. In an e-mail to customers, staff said the gas could cause vehicles to sputter, lose power, or not start. The company said it will be paying for repairs.

A second victim told FOX 2 that Costco staffer told her E-85 gas was put in the pumps by accident and that’s what caused the issues.

Here’s a copy of the e-mail Costco sent to customers on Monday:
