How far can a vehicle travel on one tank?
The Fuel Range Calculator estimates how far your vehicle can travel on a full tank based on tank capacity and fuel economy. Crucial for planning drives through remote areas, knowing when to refuel, and understanding your vehicle's real-world range capabilities.

How it works
Fuel Range Calculator: inputs, formula, and result
Enter the values that describe your high priority scenario. The interactive result changes as the inputs change, helping you compare fuel efficiency, fuel consumption, fuel cost, or operating impact.
Formula
Range = Tank Capacity (gallons) × Vehicle MPG
Worked example
A 16-gallon tank at 30 MPG gives a range of 16 × 30 = 480 miles.
Pro tip: Your usable range is less than the mathematical maximum. Plan stops at 85-90% of your calculated range for a safe buffer.

FAQ
FAQs about Fuel Range
3 questions
Question 1 of 3 is open
How far can I drive on empty?
Most vehicles can drive 25-50 miles after the low-fuel warning, but this varies widely. Never intentionally drive on empty as it can damage the fuel pump.
Why does my real range differ from the dashboard estimate?
Dashboard estimates are based on recent driving patterns. If you switch from highway to city, the estimate drops. It is a projection, not a guarantee.
Which vehicles have the longest fuel range?
Diesel trucks with large tanks can exceed 800 miles. The Toyota Camry Hybrid can travel over 680 miles. Honda Civic and Hyundai Elantra reach 500+ miles per tank.
