US Fuel Prices Hit Labour Day Record Amid Iran War
Gasoline costs more in the United States this Labour Day than ever before.
The average price is USD 4.14 per gallon.
Diesel is even more expensive, reaching USD 5.85 per gallon.
Higher diesel prices can make deliveries and groceries cost more.
The conflict involving Iran and reduced shipping through the Strait of Hormuz have affected fuel supplies.
Refineries in the United States and other countries are also producing less fuel or facing risks from extreme weather.
The Energy Secretary says prices may fall in the coming months.
Experts say prices are difficult to predict, so drivers are using price apps to find cheaper stations.
The average US regular-gas price reached USD 4.14 per gallon before Labour Day.
That price was nearly USD 1 higher than last year and exceeded the previous Labour Day record of USD 3.82 in 2012.
Diesel reached a record national average of USD 5.85 per gallon, raising freight and delivery costs.
The Iran conflict, reduced Strait of Hormuz traffic, and refinery supply problems have pushed prices higher.
Officials expect prices to fall, but experts warn heat, hurricanes, and global refinery disruptions could prolong high costs.

Future gasoline prices

Continued Uncertainty
Energy experts said prices remain unpredictable because of the Iran conflict, refinery constraints, extreme Texas heat, and possible hurricane disruptions.
Main supply pressures
