Why Gas Prices Rise and Fall: Gasoline vs Crude Oil
Pump prices can feel random, but they mostly follow one thing: crude oil. This guide shows how U.S. gasoline has tracked crude since 1995, why the two don't move in perfect lockstep, and what the gap between them — taxes, refining and dealer margins — actually pays for.
Do gas prices follow crude oil?
Overwhelmingly, yes. Crude oil is the single biggest component of a gallon of gasoline, so the two lines above rise and fall together. When you convert crude from dollars-per-barrel to dollars-per-gallon (a barrel holds 42 gallons), the gasoline line sits a fairly steady distance above the crude line — that distance is everything that isn't the oil itself.
Why isn't gasoline just the crude price?
A gallon of crude is not a gallon of gas. The gap — the spread in the second chart — pays for refining crude into gasoline, shipping it, station overhead and profit, and taxes: roughly 18.4¢ federal plus state taxes that range from about 9¢ to over 60¢ a gallon. That's why two stations across a state line can differ by 50¢ on the same crude price.
What moves crude oil in the first place?
Global supply and demand. OPEC production decisions, U.S. shale output, recessions (which crush demand) and geopolitics all swing the price. You can see the landmarks in the chart: the 2008 spike toward $140 a barrel, the 2020 pandemic collapse (crude briefly went negative), and the 2022 surge after Russia's invasion of Ukraine.
Why do gas prices rise fast but fall slowly?
Economists call it “rockets and feathers”: when crude jumps, pump prices shoot up within days; when crude falls, prices drift down slowly. Stations pass cost increases through quickly but hold the savings longer, which is why a drop in oil can take weeks to show up at the pump.
What you actually pay for in a gallon of gas
The pump price breaks into four parts. Crude oil is the biggest, typically around half the total. Taxes — federal plus state — add a fixed chunk that varies widely by state. Refining turns crude into gasoline, and its cost climbs when refineries are strained or switching to summer blends. Distribution and marketing covers shipping the fuel and running the station. When the pump price moves day to day, you’re mostly watching the crude-oil slice change — the other three are far steadier.
Frequently asked questions
When were U.S. gas prices at their highest?
Inflation-adjusted, the 2008 spike and the June 2022 peak (a national average near $5.00 a gallon) were the highest in modern history.
What share of the gas price is crude oil?
Typically 50–60% of the retail price. The rest is taxes, refining, distribution and margins — the spread shown above.
Why are gas prices so different by state?
Mostly state taxes and fuel blends. California runs highest because of high taxes and a special low-emission blend; Gulf-Coast states are cheapest.
Do gas prices follow oil immediately?
No — there's usually a lag of days to a couple of weeks, and prices tend to rise faster than they fall.
