Expect some long lines at the pump Wednesday morning at the Kroger Store in Irving, Texas.

Kroger and General Motors have teamed up to sell E85 at that site for just 85 cents per gallon between 7:30 am and 9:30 am on August 8 as part of a promotion to spotlight GM’s flex fuel vehicles. The price is nearly 70 percent below the current price of more than $2.54 per gallon. Only flex-fuel vehicles can use 85 percent ethanol, but regular cars will be able fill up on E10 during the promotion for 20 cents off the regular price.

The first 100 customers with GM FlexFuel vehicles to fill up with E85 will also receive $25 Kroger refueling cards. Three of GM’s Chevrolet flex-fuel vehicles will be on display at the event – the Impala, Tahoe and Silverado.
