Finally Under $4; The Gas Price Plunge Continues

Iowa's gas prices fell 80 cents over six weeks

Iowa's gas prices dropped another 23 cents in the last week bringing the statewide average under $4. The state is now on a six-week gas price decline, having dropped 80 cents since the new record was set on June 15th this year.

Tuesday, the average price for gasoline was $3.96 per gallon. This time last year, the price was $3 a gallon. On average it costs about $59 to fill an average-sized 15-gallon tank of gas. That's $12 less than what drivers paid when gas prices hit their peak of $4.76 in mid-June.

"For the first time in a couple months, drivers most Iowa cities are beginning to find pump prices below $4 a gallon," said Meredith Mitts, spokeswoman, AAA - The Auto Club Group (Minnesota/Iowa). "Oil prices, along with demand fell over the last several weeks, which allowed the prices at the pump to decline to the level they are at now."

"That said, new data from the Energy Information Administration shows that, while still lower than last year, gas demand increased over this past week. This, coupled with a $2.28 increase in crude oil prices could pressure pump prices and slow the decrease we are seeing," Mitts continued. "It's important to remember that the market remains extremely volatile, and prices have the potential to bounce back. That particularly applies to hurricane season. If a major storm makes landfall along the gulf coast, impacting operations at refineries in Texas, Louisiana, or Mississippi, prices could spike, due to concerns about fuel supplies."

Ways to Save on Gasoline

  • Combine errands to limit driving time.
  • Shop around for the best gas prices in your community.
  • Pay with cash. Some retailers charge extra per gallon for customers who pay with a credit card.
  • Remove excess weight in your vehicle. Every 100 pounds taken out of the vehicle improves fuel economy by 1-2 percent.
  • Drive conservatively. Aggressive acceleration and speeding reduces fuel economy.
