Ever wondered why diesel almost always costs more than regular gas? ⛽

For most people it's a minor annoyance at the pump.

For truck drivers — it's the single biggest number in their business.

Here's why diesel is more expensive 👇

Reason 1: Higher federal tax

The federal excise tax on diesel is $0.244 per gallon.

On regular gasoline it's $0.184 per gallon.

That's a 6-cent difference built into every gallon before the state even adds its own tax.

For a trucker burning 20,000 gallons a year — that tax gap alone is $1,200 annually.

Reason 2: Commercial demand never stops

Around 70% of all goods sold in the United States move by truck.

That means diesel demand is constant, massive, and doesn't drop even in a slow economy.

Refineries and distributors price for that demand.

Reason 3: More complex refining

Modern diesel fuel requires extra processing to meet current emissions and sulfur standards.

That additional refining step costs money — and gets passed directly to the pump price.

The result:

Diesel typically runs $0.20 to $0.80 higher per gallon than regular gasoline.

And for truck drivers, the numbers are brutal 👇

📊 Average miles per year: ~100,000–125,000
📊 Average fuel efficiency: ~6–6.5 MPG
📊 Gallons burned per year: ~16,000–20,000
📊 At $4/gallon: $64,000–$80,000 in fuel annually

Fuel is 25–35% of an owner-operator's total operating costs.

That means:

Every $0.10 increase in diesel price = $1,600–$2,000 more per year

Every $0.50 spike = $8,000–$10,000 more per year

Out of the same revenue.

This is why every trucker watches diesel prices the way some people watch stock prices.

It's not background noise.

It's the number that decides how much is left at the end of the month. ⛽
