Parma-area drivers: diesel eases, regular holds steady in AAA Boise metro (June 22)

AAA’s latest Boise City metro pump-price averages—used here as the closest metro proxy for Parma-area drivers—show regular unleaded at $4.1470 per gallon as of June 22, 2026. That’s essentially flat compared with $4.1410 yesterday. Diesel is easing instead: $4.8650 per gallon today, down from $4.8800 the day before.

Regular gas: steady today, down from last week

The Boise City metro regular gas average is $4.1470 now. It was $4.3080 a week ago and $4.6680 a month ago. Even with today’s steadiness, regular gas is still $3.3140 compared with the same time last year—about 83 cents higher.

Diesel: lower vs. yesterday, week, and month

For diesel users, the move is more noticeable. The Boise City metro diesel average is $4.8650 today, below $4.8800 yesterday. It’s also below $5.0820 from last week and $5.6310 from last month. Diesel remains elevated versus year-ago levels at $3.5670—about $1.30 higher.

Quick statewide and national context

Compared with AAA’s statewide Idaho averages, Boise metro regular gas ($4.1470) is a bit lower than the Idaho regular average ($4.2400), while diesel ($4.8650) is also slightly under the Idaho diesel average ($4.9700). AAA’s national regular average is $3.9290—so Boise metro drivers are still paying more at the pump.

What this means around Parma

When regular gas holds steady but diesel drops, the budgeting effect can be uneven. Commuters who put mostly gasoline in their tanks may see less day-to-day relief, while people who buy diesel for work—delivery drivers, contractors, service fleets, and other fuel-reliant businesses—are more likely to feel today’s easing in their operating costs.

Because these are metro averages, individual station prices in the Parma/Canyon County area can still vary. But the overall direction in the Boise metro is a practical signal for anyone planning routes, job scheduling, or weekly fuel budgets.

Why retail prices still wobble

EIA’s Gasoline and Diesel Fuel Update explains that a retail gallon reflects multiple components, including crude oil, refining, distribution and marketing, and taxes. When those pieces shift week to week, pump averages can move up or down even without a single local headline.
