Drivers are getting relief at the pump, but will it last?

The average pump price has fallen nationally for regular unleaded gasoline for 17 consecutive days, providing customers with a total savings of 12 cents per gallon. The national average currently sits at $2.20 per gallon, the lowest price since February, according to a report by AAA.

Gas customers can thank low crude oil prices as well as ample domestic supply for the falling pump prices, which could dip below a $2-per-gallon national average before the end of the year.

Already eight states are posting averages below the $2-per-gallon mark, with consumers in South Carolina ($1.89) paying the lowest amount per gallon in the country. Meanwhile, Hawaii ($2.89) continues to hold the lead for the highest national average price for gas, with California ($2.85) hot on its heels.

Significant year-over-year discounts on gasoline continue. In fact, drivers 45 states and Washington, D.C. are saving at least 75 cents per gallon when they refuel their vehicles compared to last year.
