5 surprising facts behind the fuel powering your summer road trip

Follow gasoline’s fascinating journey—from deep underground to your car’s tank.

Whether you're chasing sunsets on Highway 1 or exploring classic roadside diners along I-10, there's one constant behind every summer road trip: fuel. But while we focus on the playlist, the snacks and the scenery, we may not think much about the gasoline that powers our adventures.

And that gasoline has been on an incredible journey of its own—one that started thousands of feet underground and then continued through a complex network of oil wells, refineries, and distribution systems before reaching a filling station.

So before you hit the road on your summer adventure, let's take a quick detour into the story of how your gas gets from the ground to the pump.

1. Some oil wells are drilled deeper than 24,000 feet. That’s more than four times deeper than the Grand Canyon!

oil discovery and extraction

Gasoline begins as crude oil buried deep below the Earth’s surface. When geologists are looking for oil, one method they use is sending sound waves deep underground. The echoes help them find and map oil-rich rock formations.

did you know?
In some oil reservoirs, pressure can exceed 5,000 pounds per square inch (psi)—that’s more than 300 times the pressure in a car tire.

Drilling for oil: Once the oil is found, companies drill into these reservoirs to extract the crude oil.

2. The U.S. has more than 190,000 miles of petroleum pipelines—enough to circle the earth almost 8 times.

transporting oil to refineries

Crude oil is not usable when it’s first extracted. It has to be processed at refineries to remove impurities. Crude oil can travel hundreds or thousands of miles via barges, pipelines and trucks to reach these refineries.

Oil pipelines: Petroleum pipelines transport crude oil and gasoline across the country. The Colonial Pipeline is the longest pipeline system in the U.S. It encompasses approximately 5,500 miles of pipe.

3. Producing gas requires a lot of heat. In fact, the refining process can reach temperatures higher than 1,100°F (590°C), which is close to the temperature of molten lava.

oil refining process

Refining crude oil into fuel products is a complex process with many steps. It starts with distilling oil into fuels, like gasoline, and ends with blending additives into the finished products. Finished gasoline undergoes more refining to remove impurities and improve quality.

Gas additives: Additives like detergents are added to fuel to help clean your car’s engine and improve its performance.

4. Standard Oil Company, a Chevron legacy company, opened its first gas station in 1907, in Seattle, Washington. Before then, gas could be purchased at general stores, pharmacies and blacksmith shops.

distributing fuel to gas stations

Before gas or diesel fuel gets to your car, it makes a couple more stops. First, a network of pipelines delivers it to terminals, where it’s stored in above-ground tanks. Tanker trucks then take it from terminals to filling stations.

Where to fuel up: There are approximately 145,000 fueling stations in the U.S.

5. In 1929, gasoline cost about $0.21 per gallon. This means it would have cost upward of $2 to fill up the Ford Model A. Adjusted for inflation, the price would be more than $39 today.

hitting the pump before your summer road trip

At one time or another, most people have seen tanker trucks parked at gas stations with fuel lines connected to points on the ground near pumps. Those lines are sending gasoline from the trucks to underground storage units at the station. And that's where it waits, ready for you to roll up and fill your tank!

So the next time you fuel up for a spontaneous weekend escape or a long-planned road trip, think about the journey your gas has already taken—long before you merge onto the highway.

From oil wells to fuel pumps, the journey relies on engineering, logistics and innovation—working together so you can roll down the windows and enjoy the ride.
