GRAND RAPIDS, Mich. (WOOD) — With gas prices declining throughout the week, one gas expert advises drivers to wait until the weekend to refuel.

“If you’re not in any hurry, I would wait to fill up. Potentially later this week toward the weekend, prices should be 5 or 10 cents lower by next week at this time,” said Patrick DeHaan, the head of petroleum analysis at GasBuddy.

By the time Labor Day rolls around in a few weeks, DeHaan said we could see a jump similar to what we’ve seen recently. He said to expect the holiday to bring gas prices in the mid to upper $3 range.

“At this point, we shouldn’t see prices going up beyond what they already have. We could see them eventually making another jump to let’s say, $3.65 or $3.75 by Labor Day.”

If something like a major hurricane that impacts refineries in Texas or Louisiana happens, we could hit the $4 per gallon mark, according to DeHaan.

Already, the price of oil has been rising for six straight weeks. The higher prices can be attributed to heat and world markets.

High temperatures over 115 degrees in Texas have caused issues for refineries. A lot of the sensors and electronics don’t work as well in the heat, and liquids expand, reducing the capacity of refineries.

“Essentially, they aren’t able to produce as much when temperatures are so high,” said DeHaan.

Across the world, more cooperation between Russia and Saudi Arabia is cutting oil production, which is pushing prices up.

“That’s going to entice U.S. producers to start pumping more, to start drilling more. … As oil prices go up, there’s more incentive for US oil companies to increase production. And that could eventually bring prices back down.” He said that could take a bit more time.
