Your Fill-Up Is Still Near $4.37 After the Most Expensive September on Record.

AAA has regular gas near $4.37 and diesel still around $6.30. September was the most expensive September ever at the pump. The grocery truck already paid the diesel bill.

The pump is still loud

As of October 7, AAA put the national average for regular gas near $4.37 a gallon. That is down a little from the prior week, and still far above a year ago near $3.12.

Diesel is the uglier line. National diesel still sat near $6.30 a gallon after setting an all-time high around $6.53 in late September.

September was the most expensive September on record for regular gas. August had already been a record August. Two months in a row of "most expensive ever for this month" is not a one-day blip on a chart.

Why diesel matters more than the meme

Most people feel regular gas first. The wider bill often runs through diesel.

Trucks move groceries, clothes, building materials, and almost everything else on a shelf. When diesel stays elevated, the cost shows up later as higher prices in the cart, not only as a bigger number on the highway sign.

California still sits near $6.30-plus for regular. Plenty of states are cheaper. The national average is what most headlines use, and it is still stuck in the mid-$4s after a brutal stretch.

Oil is not calm either

Brent has been fighting around and above $100 a barrel. U.S. crude has been working near the high $80s to low $90s. Middle East flows, tanker risk, and tight product markets keep the pump story alive even when one session settles lower.

Final Thoughts

A few cents off the weekly average is not the same as cheap gas. After the most expensive September on record, a fill-up near $4.37 and diesel near $6.30 still tax the commute and the grocery truck.

Watch the pump and the diesel line. That is the receipt.
