Fuel stop planning — how much extra fuel should you carry?

April 5, 2026

Quick Answer

For safe fuel stops, carry an extra 20-30% of your vehicle's fuel capacity, considering your vehicle's fuel efficiency and the average fuel consumption on your evacuation route.

Calculating Fuel Reserves

When planning fuel stops, it’s essential to consider your vehicle’s fuel efficiency, the average fuel consumption on your evacuation route, and the terrain you’ll be driving through. As a general rule, add 20-30% to your vehicle’s fuel capacity to account for unexpected detours or challenging driving conditions. For example, if your vehicle has a 20-gallon fuel tank, add 4-6 gallons of extra fuel to ensure you have enough to reach your destination.

Route Planning and Terrain Considerations

When planning your evacuation route, consider the terrain and road conditions you’ll encounter. Mountains, deserts, and other challenging environments can significantly impact fuel consumption. Research the route ahead of time and factor in any potential obstacles, such as road closures or construction. This will help you estimate your fuel consumption and plan for adequate fuel reserves. Consider using a mapping app or GPS device to help you navigate and estimate fuel consumption.

Fuel Stop Frequency and Duration

When planning fuel stops, consider the frequency and duration of each stop. Aim to stop every 2-3 hours or when your fuel level reaches 1/4 of a tank. This will give you enough time to refuel and rest before continuing on your journey. When refueling, try to fill up to at least 80% of your tank to minimize the risk of running out of fuel. Additionally, consider the safety of your fuel stops, choosing well-lit and populated areas whenever possible.
