If you’re paying around $3.75 a gallon in Florida right now, it feels like the spike already happened.
It didn’t.
What you’re seeing at the pump reflects oil prices from about a week or two ago—when crude was trading closer to $80 a barrel. But for the past several days, oil has been holding above $90.
That difference matters. A lot.
The math behind the pain
There’s a simple rule in the fuel business:
-
Every $10 increase in crude oil adds about 25 cents per gallon of gasoline.
We’ve gone from roughly $67 to $90 per barrel—a $23 jump.
That translates to:
-
About 55–60 cents more per gallon
So if gas was sitting in the low $3 range not long ago, today’s $3.75 lines up.
But here’s the catch: The system hasn’t fully caught up yet.
Why prices are still moving up
Gasoline doesn’t come straight from the oil market to your tank overnight.
There’s a lag:
-
Oil is bought
-
Refined into gasoline
-
Shipped through pipelines and terminals
-
Delivered to stations
That process takes about 10 days to a few weeks.
And here’s the part that matters: All this talk about $3.75 per gallon, that’s based on $80 a barrel of oil. Since March 9, oil hasn’t dipped below $90.
The pump just hasn’t caught up yet.
The part nobody talks about
Gas prices aren’t based on what stations paid for the fuel already in their tanks.
They’re based on what it will cost to replace it.
That means even before higher-priced fuel arrives, stations start adjusting upward—because they know the next delivery will cost more.
It’s not gouging.
It’s survival in a tight-margin business.
And then there’s the “nervous system”
Oil didn’t just rise—it rose during a period of instability.
That brings:
-
Shipping risk through the Middle East
-
Higher insurance costs
-
Tighter refining margins
All of that adds extra pressure on gasoline prices beyond the raw cost of crude.
What comes next
If oil stays above $90:
-
Expect gas in Florida to move toward $3.90 to $4.20
If oil pushes toward $100:
-
$4+ gas becomes the norm, not the exception
If oil drops back into the $80s:
-
Prices may stabilize—but they won’t fall quickly
Bottom line
That $3.75 you’re paying today isn’t the peak.
It’s the market catching up to yesterday’s oil prices—
while today’s higher prices are still working their way through the system.
In other words:
The number on the pump is always a step behind the number on the barrel.
