When gasoline prices go up in your neighborhood it’s hard to imagine that anyone else has it worse. Who’s got the worst price volatility in the country? Which markets see the steepest price hikes? Where do the gas stations and convenience stores change the prices most frequently? GasBuddy found the answers.

“While small cities lead the way among markets with the steepest price spikes, we saw some larger Midwestern cities like Chicago, Milwaukee and Detroit positioned prominently among the leaders for days with one cent or more price increases (see maps for more information), and that undoubtedly fuels consumer anxiety in places where there’s plenty already,” said Gregg Laskoski, another senior petroleum analyst with GasBuddy.

“But when we look at the number of days with average price decreases of more than a penny, we see the Midwestern cities more than doubling every other region in the country,” DeHaan noted, “and it’s the downside of that rollercoaster ride that consumers easily forget. We complain about the higher highs, but we’re quiet when we benefit from the lower lows!”
