Some petroleum analysts expect gas prices to spike 15-30 cents over the next week for drivers in the Midwest after BP partially shut down a large refinery in Whiting, Indiana for unplanned repairs.
GasBuddy.com reports drivers in Illinois and Ohio will see the spike. Kentucky and Missouri may also be affected.
The refinery, located near Chicago, is one of the largest in the country and the largest in the Midwest. It's operating at 44 percent of its 430,000-barrels-per-day capacity during the outage.
According to GasBuddy, prices in Illinois are currently averaging $2.84 per gallon – 20 cents more than the national average. Average prices in Kentucky remain around 20 cents lower than the national average.
