The Lundberg Survey found gas prices down 3 cents nationally in the last two weeks.
The survey also says Chicago has the highest gas rate, at $4.10 per gallon.
"Even though they say the prices are dropping it doesn't seem that way. I'm paying a lot," said Alvin Hill.
Hill is a therapist who travels to 10 to 20 locations each week. He says the cost of gas is cutting into his income.
On Monday, Hill decided to fill his tank only halfway.
While Chicago is usually among the most expensive cities for gas, the costs are much lower prices than a year ago, according to gasbuddy.com.
"Prices are at $4.07 which, believe it or not, is 50 cents lower than it was a year ago today. And a year ago today Chicago was in the top due to unique refining issues," said Patrick Dehaan, senior petroleum analyst for gasbuddy.com
Dehaan says he believes prices this spring and summer will be lower than last year, but there could be some fluctuation as local refineries do maintenance and the BP refinery completes its renovations in Whiting.
"The market is expecting that facility to be open in the summer if there are problems that significantly delay the opening you can bet there will be some sort of increase in price," said Dehaan.
For now, the trend appears to be going down- although slightly.
Nicky Von Kondrat says she sees the bigger global picture as she fills up her SUV with $70 in gas.
"We're paying pennies to the gallon on what the rest of the world pays for gas and it would nudge us into more environmental friendly action," she said.
The study reported that the lowest gas prices are seen in Montana, at $3.33 per gallon.
And gasbuddy.com reports higher prices in California and Hawaii.
