West Texas Intermediate crude closed below $60 a barrel this week, a level traders hadn't seen in roughly four years.
The drop caps a months-long slide driven by swelling global supply and softer demand from major economies.
For anyone who drives, flies, or buys groceries, the number matters more than it might seem.
GasBuddy data already shows the national average for regular gasoline dipping toward $3.05 a gallon, with several Southern and Midwestern states under $2.80.
Analysts at GasBuddy project the national average could test the $2.90s before Memorial Day if crude holds near current levels.
That would mark the cheapest summer driving season since 2021.
The ripple effects extend well past the pump.
Diesel, which powers most freight trucks, has fallen even faster than gasoline on a percentage basis.
Lower diesel costs typically work their way into retail prices within four to eight weeks, meaning shelf prices on everything from cereal to cleaning supplies could see modest relief into early summer.
Jet fuel is the second-largest expense for most carriers after labor, and sustained crude weakness often precedes fare sales on domestic routes.
Southwest and Delta have both trimmed fuel cost forecasts for the current quarter, a signal that ticket prices could soften on competitive routes by late spring.

The best move right now isn't to wait for prices to fall further before filling up.
It's to use the window to pay down higher-rate debt or pad emergency savings while fuel costs are working in your favor.
Rate cuts from the Federal Reserve remain uncertain, and credit card APRs are still averaging above 20 percent.
One more thing worth watching: home heating oil and propane contracts for next winter get priced in late summer.
If crude stays weak through July, lock-in offers this fall could come in noticeably cheaper than last year's.
Utilities in the Northeast have already flagged lower forward costs in regulatory filings.
Oil is one of the most volatile commodities on earth, and a single OPEC+ decision or supply disruption can erase months of declines in a week.
Treat the current relief as a temporary gift, not a new normal.
The bottom line: cheaper crude is quietly putting money back in American pockets right now, but the window is likely measured in months, not years.
Final Thoughts
Use it deliberately, because the same market that giveth at $58 can taketh away at $75 before Labor Day.
