Consumers should not expect gas prices to continue to move downward, he said.
"I don't think we will continue to see much more movement in gasoline prices from where they are today through Labor Day," Faulkner said. "I predict gas will remain range-bound, so the old saying of 'what you see is what you get' applies to gas prices as they are today."
Despite the growing turmoil in the Middle East, global oil prices along with U.S. gasoline prices declined in recent months, said Bernard Weinstein, associate director of the Maguire Energy Institute at Southern Methodist University in Dallas.

The oil production from shale plays continues to expand at a rapid pace in the U.S. with production rising 50% in just the past three years.
"This has helped put downward pressure on both global oil prices and domestic gasoline prices," he said. "Since we're importing a lot less, more oil is available for the rest of the planet from OPEC and other non-OPEC producers."
Drivers should be "relatively happy" this Labor Day because gasoline prices are at a four-year low, Weinstein said.
"I bought regular gas today for $3.09 and some stations in Texas are actually just under $3.00 a gallon," he said. "Barring some global political catastrophe, such as NATO going to war with Russia, I believe oil and gasoline prices will remain stable or decline slightly during the fall and winter."
Prices should remain fairly steady for the weekend, said Clint Werth, general manager of supply and trading of Atlas Oil Company, a Taylor, Mich. national fuel supply and distribution company.
"Over the next 30 days, we should see some decline as we move out of summer grade gasoline," he said. "These predictions can be easily disrupted by a hurricane, refinery issue or a change in a geopolitical issue."
One of the best ways to save money is to fill up your tank on Wednesday or Thursday before 10 a.m., said Faulkner. Buy gas when it's cooler during the day such as early morning or at night to reduce gas evaporation.
"Gas prices rise on Thursdays in anticipation of weekend travel," he said. "Unless it is an emergency, do not buy gas on Friday, Saturday or Sunday."
Paying attention to your car's warning signs such as the 'check engine' light can alert drivers to problems that affect their car's emissions output, reduce fuel economy and cause mechanical damage, said Art Jacobsen, vice president of CarMD.com Corp., the Irvine, Calif. provider of automotive information.
"While it may seem like your vehicle is driving just fine, it's often guzzling extra gasoline," he said.
The number one most common cause for "check engine" repairs is a faulty oxygen sensor, which measures the amount of unburned oxygen in the exhaust and tells a car's computer when there is either too much or not enough fuel compared with oxygen for ideal operation.
"It costs less than $250 to fix, but can lead to as much as a 40% reduction in gas mileage if ignored that's more than $900 extra per year in fuel costs," Jacobsen said.
To find the best deals for gasoline, websites such as GasBuddy.com display gas station maps with prices, said Villanova School of Business Economics Professor Peter Zaleski.
"Most newer cars display an mpg gauge," he said. "Drivers can utilize that feature to determine what driving styles maximize mpg.
Consumers should check their credit card rewards programs since several of the "quarterly bonus" cards have gas as their bonus category, said Matthew Goldman, CEO of Wallaby, the Pasadena, Calif. credit card rewards maximizer.
