Gas prices remain close to $4 per gallon of regular unleaded in the Kankakee Valley. GasBuddy.com senior petroleum analyst Patrick DeHaan says they should have dropped by the middle to end of May. He says there’s no specific reason but notes wholesale prices are higher. DeHaan says he’s been waiting for prices to drop or trends to shift. He says the tipping point that should revert to a downward trend should occur at any time, but it hasn’t happened yet. Meanwhile, he says refineries are looking good and production is up, so he doesn’t expect gas prices to go up considerably more before they eventually drop.
