$2.05/g in 2016, $1.80/g in 2015, $2.30/g in 2014, $3.05/g in 2013 and $3.05/g in 2012.

"As we approach Christmas, average gas prices in the U.S. have fallen to their lowest point in 110 days, just as Hurricane Harvey began causing prices to spike, not exactly the Christmas gift some hoped for, but it's about time nonetheless," said Patrick DeHaan, head of petroleum analysis for GasBuddy.

 "As long as demand for gasoline continues to weaken, gasoline inventories will continue growing and it'll be the gift that keeps on giving. In addition, the gap between prices today and a year ago is also at its narrowest in months, highlighting that prices are moving in the right direction for many.

“ As we look towards our annual Fuel Outlook being released just after the New Year, there are some bright spots along with some concerns that lay ahead for 2018."
