MINNEAPOLIS (WCCO) — Drivers taking that summer road trip can expect to see even more savings at the pump in the coming weeks.

According to AAA, the average price for a gallon of gas has dropped for 21 days in a row.

Nationwide, the average price for gas is $2.59 a gallon. In Minnesota, drivers are paying about $2.50 a gallon.

AAA reports that the reason behind the price drop is that cheaper crude oil is driving down prices.

In July, oversupply brought down the cost of crude oil for the second year in a row.

Also, some refinery issues, that slowed production, have been worked out.

Some gas stations around the Twin Cities are coming in as low as $2.33 a gallon. In areas like Rochester, some stations are selling gas for $2.06 a gallon.

“It’s all about the distribution, where they get their fuel from, which refineries, which pipelines or oil tankers and those sorts of things,” said Gail Weinholzer of AAA. “It’s all about the distribution, where they’re getting it from. Some are getting it less expensive than others, but we’re all going to catch up.”

If $2.33 for a gallon of gas sounds like a good deal, AAA says the cost should be even lower considering that crude oil is so cheap.

But we are driving more than ever, so the demand for fuel is higher.

After the summer travel season ends in September, the price should drop even more. According to AAA, it could fall another 15 cents.

In the fall, gas stations start using the less expensive winter blend.
