Douglas County drivers feel gas price squeeze amid Iran war ripple effect

Gasoline is once again biting into household budgets in Douglas County, and the clearest local snapshot is a 7-Eleven at 19832 E Hilltop Rd. In Parker, regular gas listed at $4.899 a gallon, with mid-grade at $5.399 and premium at $5.699, a price spread that turns a routine fill-up into a bigger line item for families already watching every expense.

That pain lands especially hard in Douglas County because driving is not optional for most residents. The county’s population was estimated at 399,396 on July 1, 2025, with 139,960 households and a median household income of about $152,657, but those figures do not erase the county’s car dependence. Census Reporter’s ACS profile shows a mean commute of 28.1 minutes, 63% of workers driving alone and 30% working from home, underscoring how many daily trips still run through Castle Rock, Parker, Lone Tree, Highlands Ranch, Castle Pines and the I-25 corridor.

The broader market backdrop explains why local prices feel so sharp. AAA said Colorado’s average gas price stood at $4.646 on May 25, after sitting at $4.693 two days earlier, while the national average was $4.507. That puts Colorado above the U.S. average even before adding the local premium seen on Hilltop Road. Colorado Springs was already averaging $4.843 on May 20, showing the Front Range was not insulated from the surge.

The pressure is tied to the war with Iran and fears over global oil supply, especially the Strait of Hormuz, which carries about one-fifth of the world’s crude. CNBC reported May 22 that U.S. gas prices were up more than 50% since the conflict began on Feb. 28, and that prices could reach $5 a gallon this summer if the strait does not reopen. The timing matters heading into Memorial Day, when about 39 million people were expected to travel by car and Americans were projected to spend about $2 billion more on gasoline than a year earlier. For Douglas County drivers, that means the squeeze is not just a headline about world events. It is showing up at the pump, one commute and one vacation tank at a time.
