WALNUT CREEK, Calif. – California’s average for a gallon of regular gasoline dropped seven cents in the past week to $6.07. The national average for a gallon of regular gasoline is also down, 12 cents from last week at $4.42. Crude oil prices have been going down this week amid reports of peace talks with Iran. But the fragile situation could cause oil prices to spike again if a ceasefire deal isn’t reached.
“Although prices have dropped after Memorial Day demand passed, gas prices remain the highest they’ve been in four years,” said AAA Mountain West Group spokesperson Doug Johnson. “They’ll likely remain elevated as the busy summer driving season gets underway.”

AAA Shares Tips to Help Drivers Save on Gas
Save on gas. Use the AAA Mobile App to find the cheapest gas stations along your route, plan your trip, request roadside assistance, and more. AAA Members can save 30¢ per gallon on your first fill-up at participating stations when you join Shell Fuel Rewards®. All AAA Shell Fuel Rewards® Members save 5¢ per gallon on their fill-ups of up to 20 gallons at participating stations with complimentary Gold Status.
Avoid Speeding: Fuel economy peaks at around 50 mph on most cars, then drops off as speeds increase. Driving the recommended speed limit can increase fuel economy between 7 and 14 percent.
Regular vs. Premium: Pay close attention to the words “recommended” and “required.” If regular gas is recommended for your vehicle, that’s all you need. Choosing premium when your car doesn’t require it will only cost you money and doesn’t improve fuel economy.
Remove unnecessary weight from your vehicle (e.g., trunk, cargo area, etc.) as weight increases the amount of effort it takes to move the vehicle.
Avoid Excessive Idling: When idling, car engines use up to one-half gallons of fuel per hour. Warm engines take about 10 seconds worth of fuel to restart. Shut off your engine when stopped for more than a minute and if it’s safe to do so.
Check Tire Pressure and Align Tires: Maintaining proper tire pressure reduces your tire’s friction with the road. Less friction means less energy is needed to move, resulting in using less gas. Proper inflation can improve gas mileage by 0.6 percent on average.
