US diesel tops $6/gallon average as Iran war pushes crude past $100
AAA reported the national average diesel price reached $6.05 a gallon on Friday, up from $5.85 the prior week and $3.70 a year ago, as the conflict between the U.S. and Iran disrupts global fuel supplies. Regular gasoline also rose to $4.29 a gallon, tracking a jump in both Brent and U.S. crude oil above $100 a barrel for the first time in months.
GoKawiil's interpretation of the reporting above, not reported fact.
Because diesel powers most freight, delivery and farm equipment, these increases ripple quickly into the price of perishable groceries like meat and produce that require frequent transport. President Trump has acknowledged oil prices may stay elevated until after the November midterms, suggesting sustained inflationary pressure on consumers heading into the election.
- Diesel hit a record $6.05/gallon average, up 63% from pre-war levels in late February 2026.
- Crude oil surpassed $100 a barrel this week for the first time in months amid U.S.-Iran fighting.
- Businesses are already adding delivery fees, and grocery costs—especially perishables—may rise further as costs trickle down.
