How Many Gallons Does the Average Car Hold?

The average car fuel tank holds between 12 and 16 gallons of gasoline. This range covers the vast majority of sedans, hatchbacks, and compact crossovers on the road today. Manufacturer specifications are designed to give most passenger cars a driving range of 300 to 400 miles per tank. Therefore, the specific average gas tank size is a direct result of balancing a vehicle’s fuel efficiency (MPG) with this target range.

While the 12-to-16-gallon figure is a reliable benchmark, the true average varies based on the vehicle’s classification. You can’t expect a small, fuel-sipping compact car to have the same tank size as a large, powerful truck. Understanding these differences helps you get a much more accurate picture of fuel capacity.

Here’s a general breakdown based on automotive industry standards:

• Small/Compact Cars: Typically hold around 10 to 14 gallons.
• Mid-size Sedans & Crossovers: Usually have a capacity of 14 to 18 gallons.
• Large SUVs & Trucks: Can range significantly from 19 to 36 gallons or more.

How Does Fuel Capacity Vary by Vehicle Type?

A vehicle’s class is the single most significant factor determining its fuel tank capacity. A subcompact car designed for city driving has very different needs than a heavy-duty truck built for towing. Manufacturers match the tank size to the vehicle’s intended purpose, engine size, and expected fuel consumption.

Our analysis of manufacturer specifications provides a clear breakdown of what you can expect from different types of vehicles. The following table offers a detailed comparison of typical fuel tank sizes across the most popular vehicle classes, including examples you’ll recognize. This data is essential for anyone comparing a sedan vs. an SUV, for instance, and wondering about the difference in refueling stops.

Pickup Trucks	20 – 36 Gallons	Ford F-150, Chevrolet Silverado, Ram 1500

What Key Factors Determine a Car’s Gas Tank Size?

The main factors determining a car’s gas tank size are the manufacturer’s target driving range and the vehicle’s fuel economy (MPG). While it might seem random, there is a clear engineering logic behind why a Toyota Camry holds 15.8 gallons and a Ford F-150 can hold up to 36. It’s a calculated decision based on several interconnected variables.

From years of working with vehicle specifications, we know that automakers aren’t just picking a number out of thin air. They are solving an equation. Here are the key factors that go into determining a car’s fuel capacity.

• Target Driving Range: The primary goal for most manufacturers is to ensure a vehicle can travel between 300 and 400 miles on a single tank. This is considered the sweet spot for driver convenience, reducing the frequency of stops on long trips.
• Fuel Economy (MPG): This is the other side of the driving range equation. A car with high MPG needs less fuel to travel 300 miles, so it can be equipped with a smaller, lighter tank. Conversely, a vehicle with low MPG (like a large truck) needs a much larger tank to achieve the same target range.
• Physical Space and Chassis Design: A gas tank can only be as large as the physical space available in the vehicle’s chassis. Engineers must fit the tank around other components like the exhaust system, suspension parts, and spare tire, all while adhering to strict federal safety standards.
• Vehicle Weight and Purpose: The intended purpose of the vehicle plays a major role. A heavy-duty truck designed for towing will consume fuel much faster under load, necessitating a larger tank to provide a practical range.

How Do You Calculate Your Car’s Potential Driving Range?

To calculate your car’s driving range, you simply multiply its fuel tank capacity in gallons by its average miles per gallon (MPG). This straightforward formula gives you a powerful tool to understand your vehicle’s capabilities. It transforms the abstract number of “gallons” into a tangible distance you can travel.

Based on practical application, this calculation is invaluable for planning road trips, deciding when to refuel, and even identifying potential issues if you notice your actual range suddenly dropping. Here is the step-by-step process.

1. Find Your Fuel Tank Capacity: The most accurate number is listed in your owner’s manual, usually in the “Specifications” or “Capacities” section. If you don’t have the manual, a quick online search for your car’s make, model, and year will provide this information.
2. Determine Your Average MPG: Your car’s trip computer often shows your average MPG. For a more accurate real-world number, you can calculate it manually by dividing the miles driven between fill-ups by the number of gallons you put in the tank.
3. Multiply to Find Your Range: With the two numbers above, perform the calculation.

The Formula:
Driving Range (Miles) = Fuel Tank Capacity (Gallons) × Average Fuel Economy (MPG)

Worked Example:
Let’s say you have a mid-size sedan with a 15-gallon tank and your real-world testing shows you get an average of 25 MPG.
15 Gallons × 25 MPG = 375 miles of potential driving range.

It’s important to remember this is an estimate. Your actual range will vary based on driving conditions like city traffic versus highway cruising, your driving habits, weather, and the weight you are carrying.

FAQs About How Many Gallons Does the Average Car Hold
