Gas prices in most states, including Oregon, continue to tick down. Gas prices have been trending lower since late June, even with record travel over the Independence Day holiday period. For the week, the national average for regular falls three cents to $3.15 a gallon. The Oregon average dips two cents to $4.02 a gallon.

“Pump prices should continue to ease if we don’t see tensions flare up again in the Middle East or a hurricane impacting the Gulf Coast,” says Marie Dodds, public affairs director for AAA Oregon/Idaho.

The Oregon average for regular gas began 2025 at $3.45 a gallon and is currently at $4.02. The highest price of the year so far is $4.076 on June 24 and 25. The lowest price of the year so far is just under $3.45 a gallon on January 2.

The national average began 2025 at $3.06 a gallon and is currently at $3.15. The highest price of the year so far is $3.268 on April 4. The lowest price of the year so far is $3.06 on January 5.

Gas prices typically rise starting in mid-to-late winter and early spring as refineries undergo maintenance ahead of the switch to summer-blend fuel, which is more expensive to produce and less likely to evaporate in warmer temperatures. The switch occurs first in California, which is why pump prices on the West Coast often rise before other parts of the country. The East Coast is the last major market to switch to summer-blend fuel. Most areas have a May 1 compliance date for refiners and terminals, while most gas stations have a June 1 deadline to switch to selling summer-blend until June 1. Switch-over dates are earlier in California with some areas in the state requiring summer-blend fuel by April 1. Some refineries will begin maintenance and the switchover in February.

Gas prices usually drop in the fall, due to the switch from summer-blend to winter-blend fuel, which costs less to produce. The switch starts in September. Many areas, including Oregon, can sell winter-blend fuel starting September 15. However, Northern and Southern California require summer-blend fuel through October 31. Prices usually decline to their lowest levels of the year in late fall and early winter before increasing again in the late winter and early spring.

Meanwhile, crude oil production in the U.S. remains near record highs. The U.S. Energy Information Administration (EIA) reports that crude production in this country is steady at 13.43 million barrels per day for the week ending June 27. The record high is 13.63 million barrels per day for the week of December 6. Production has been at 13.5 million barrels per day many times since October. The U.S. has been the top producer of crude oil in the world since 2018 and has been increasing its oil production since about 2009.

The U.S. price of crude oil (West Texas Intermediate) had been mostly in the upper $60s to mid-$70s since last September. Crude prices spiked to the mid-$70s in mid-June in response to the strikes between Israel and Iran, and then the U.S. strike on Iran’s nuclear facilities, but then prices fell back into the $60s on the belief that the conflict would not have a major impact on global oil supplies. Crude prices fell in early April as markets reacted to President Trumps tariffs and the impact on U.S. and global markets. Additional downward pressure on crude prices came after the decision by OPEC+ to increase production. The lowest closing price since September was $57.13 on May 5, which was the lowest closing price since February 2021. The recent high price for crude was $80.04 per barrel on January 15, which was the highest price since last August.

Crude oil is trading around $68 today compared to $65 a week ago and $82 a year ago. In 2024, West Texas Intermediate ranged between $66 and $87 per barrel. In 2023, WTI ranged between $63 and $95 per barrel. WTI reached recent highs of $123.70 on March 8, 2022, shortly after the Russian invasion of Ukraine, and $122.11 per barrel on June 8, 2022. The all-time high for WTI crude oil is $147.27 in July 2008.

Crude prices are impacted by economic news as well as geopolitical events around the world including the current economic uncertainty, unrest in the Middle East including the recent strikes between Israel and Iran and the U.S. strikes on Iranian nuclear facilities, the war between Israel and Hamas, and the war between Russia and Ukraine. Russia is a top global oil producer, behind the U.S. and Saudi Arabia. Crude prices have been volatile after the attack on Israel by Hamas in October 2023. While Israel and the Palestinian territory are not oil producers, concerns remain that the conflict could spread in the Middle East, which could potentially impact crude production in other oil-producing nations in the region. In addition, production cuts by OPEC+ in previous years tightened global crude oil supplies, which continued to impact prices. But now the cartel boosted production by 411,000 barrels in May and June, and July, and just announced an increase for August of 548,000 barrels per day.

Crude oil is the main ingredient in gasoline and diesel, so pump prices are impacted by crude prices on the global markets. On average, about 50% of what we pay for in a gallon of gasoline is for the price of crude oil, 17% is refining, 17% distribution and marketing, and 16% are taxes, according to the U.S. Energy Information Administration.

Demand for gasoline in the U.S. decreased from 9.69 million b/d to 8.64 for the week ending June 27, according to the U.S. Energy Information Administration (EIA). This compares to 9.42 million b/d a year ago. Meanwhile, total domestic gasoline supply increased from 227.9 million barrels to 232.1. Gasoline production dipped last week, averaging 9.6 million barrels per day, compared to 10.1 million barrels the previous week.

Pump prices will likely continue to move lower in the short term, barring another flare up in the Middle East or a hurricane that impacts refining and/or distribution.

Quick stats

Oregon is one of 46 states with lower prices now than a week ago. Indiana (-12 cents) has the largest week-over-week decline in the nation. Tennessee (+3 cents) has the biggest week-over-week increase.

California ($4.55) has the most expensive gas in the nation for the 21st week in a row. Hawaii ($4.47) is second, Washington ($4.41) is third, and Oregon ($4.02) is fourth. These are the four states in the country with averages at or above $4 a gallon. This week 25 states and the District of Columbia have averages in the $3-range. There are 21 states with an average in the $2 range this week.

The cheapest gas in the nation is in Mississippi ($2.70) and Oklahoma ($2.71). No state has had an average below $2 a gallon since January 7, 2021, when Mississippi and Texas were below that threshold. At the time, the COVID-19 pandemic drove significant declines in crude oil and gasoline demand in the U.S. and around the world.

The difference between the most expensive and least expensive states is $1.85 this week, compared to $1.87 a week ago.

Oregon is one of 41 states and the District of Columbia with higher prices now than a month ago. The national average is two cents more and the Oregon average is five cents more than a month ago. Delaware (+27 cents) has the largest month-over-month increase in the nation. California (-15 cents) has the largest month-over-month drop.

Oregon is one of 49 states and the District of Columbia with lower prices now than a year ago. The national average is 36 cents less and the Oregon average is one cent less than a year ago. New Mexico (-52 cents) has the largest yearly drop. Washington (+12 cents) is the only state with a year-over-year increase.

West Coast

The West Coast region continues to have the most expensive pump prices in the nation with six of the seven states in the top 10. It’s typical for the West Coast to have six or seven states in the top 10 as this region tends to consistently have fairly tight supplies, consuming about as much gasoline as is produced. In addition, this region is located relatively far from parts of the country where oil drilling, production and refining occurs, so transportation costs are higher. And environmental programs in this region add to the cost of production, storage and distribution.

Diesel

For the week, the national average slips half a cent to $3.69 a gallon. The record high is $5.816 set on June 19, 2022. The Oregon average rises two cents to $4.49. The record high is $6.47 set on July 3, 2022. A year ago the national average for diesel was $3.84 and the Oregon average was $4.10.
