iStock/Thinkstock(WASHINGTON) — The cost of filling up the tank is still increasing across the U.S. The price of regular unleaded gas increased about 4 cents in the past week to $2.24 a gallon, according to the latest figures from the Department of Energy.

For three consecutive weeks, U.S. gas prices have inched higher as oil prices also rallied.

But even as fuel prices move higher, U.S. drivers have enjoyed a summer with the cheapest gas prices in about a decade. In fact, Americans are still paying 27 cents less than they were on this date a year ago.
