Almost every driver has been in this situation: the fuel light comes on, and you wonder how far you can really go before the tank runs dry. The answer depends largely on your vehicle’s gas mileage, fuel tank capacity, and driving conditions.
Here’s what you need to know about driving on empty, the risks involved, and how to choose a car with the best gas mileage to avoid stressful situations.
How Much Fuel Is Left When the Light Comes On?
The amount of gas left in the tank after the low-fuel warning varies by make and model. For most cars, the fuel light comes on when there are about 2–4 gallons remaining. For example:
- Toyota Prius: about 1.6 gallons left
- Toyota Tundra or GMC Sierra Denali: up to 4 gallons left
- Honda Civic: roughly 1.9 gallons before the light turns on
Some brands, like Ford, trigger the warning when the tank hits 1/16th of its total capacity rather than a set gallon level.
How Gas Mileage Affects Range on Empty
How far you can drive on empty depends not just on fuel left, but also on your vehicle’s gas mileage.
- A small car with 30+ MPG could travel 30–60 miles after the light comes on.
- Larger SUVs and trucks with lower gas mileage may only get 25–40 miles on empty.
- In ideal driving conditions, some models can even stretch to 90–100 miles before stalling.
Factors like speed, terrain, traffic, and driving style also impact range. Aggressive acceleration, heavy loads, and stop-and-go driving can all shorten how far you can go.
Why You Shouldn’t Rely on Driving on Empty
Even if your vehicle’s gas mileage allows you to squeeze in a few extra miles, driving on empty is risky. Here’s why:
- Fuel Sediment Risks: The bottom of your tank may contain impurities that can clog filters.
- Engine Damage: Sediment reaching the combustion system can cause wear over time.
- Unexpected Stops: Running out of gas in Nevada’s desert heat or on a busy highway can be unsafe.
It’s best to fill up as soon as the low-fuel light comes on rather than testing your vehicle’s limits.

Final Thoughts on Gas Mileage and Driving on Empty
Your gas mileage plays a huge role in how far you can drive when the fuel light comes on. While many vehicles give you at least 30 miles of range, relying on “E” is never a safe habit. Regular fill-ups and choosing a fuel-efficient car will help you stay safe, save money, and enjoy peace of mind on the road.
