Gas averages $4.46 a gallon, up $1.32 from a year ago; diesel near a record
Pump prices have climbed about 37 cents in a month as the war with Iran keeps oil supplies tight.
WASHINGTON — The national average price of regular gasoline was about $4.46 a gallon on Tuesday, according to AAA, about 37 cents higher than a month ago and roughly $1.32 above the same day last year, when drivers paid about $3.14.
Prices were nearly flat compared with a week ago, and slightly lower than Monday.
Diesel is the bigger worry
Diesel averaged about $6.44 a gallon on Tuesday, just below the all-time high of about $6.53 set on Sept. 22. Diesel powers most trucks, trains and farm equipment, so higher prices tend to spread into the cost of food and other goods.
Why prices are high
Oil supplies have been tight since fighting with Iran began in February and traffic through the Strait of Hormuz, a route for about a fifth of the world's oil before the war, fell sharply. Crude eased on Tuesday, but changes in oil prices usually take days or weeks to show up at the pump.
