WASHINGTON – With the official start of spring right around the corner, gasoline prices are starting to inch up, and drivers are turning to technology to direct them to the cheapest gasoline stations, CNBC.com reports. Gas prices have jumped by 12 cents per gallon this week, which is the largest weekly increase since early March 2015, according to the most recent AAA Fuel Gauge Survey.

Prices increased by double digits due to a decline in gasoline supplies, relatively strong demand and continued refinery maintenance. The national average has moved higher for 18 of the past 20 days for a total of 23 cents per gallon, and today’s price of $1.94 per gallon is the highest average in two months. Relatively low oil costs continue to provide drivers with year-over-year savings at the pump, and consumers are saving 50 cents per gallon compared to this time last year.

“As weather improves, people are hitting the road and using more fuel, while refineries are producing less gasoline,” said Michael Green, AAA spokesman. “Unfortunately there's still room for prices to go even higher, as past spring increases have been 50 cents or more.”

But there’s an app to help ease any pain at the pump. For example, apps like Gas Buddy point the way to the area’s most inexpensive gas. Google Maps and Waze map out the quickest and most efficient route to a destination, including gasoline stations. Bankrate even provides a gasoline station calculator to help determine if driving those extra miles to fill up at a cheaper station makes economic sense.
