There is a widespread misconception that when the gas light turns on, there is only one mile until it runs out. How far you can drive is actually as follows.

  • 30 to 50 miles is the consensus on how far you can drive once your gas light comes on
  • But the size of the vehicle and its condition does affect mileage left; a small will go further than a pickup truck
  • Running on empty regularly can cause damage to the vehicle; including fuel pump replacement and more
  • A Hyundai Sonata has 40 miles left to drive after gas light is triggered

Do you become panicked as soon as the gas light appears on the dashboard? Many times, there is no need to worry because there are still a lot of miles in the tank. How many miles can you drive once the gas light comes on, though you should still start looking for the closest gas station?

In this article, we’ll look at how long you can keep your car running with just a few gallons of gas left and explain why this is a bad habit to get into.

What is the Gas Light on the Dashboard?

Numerous lights on the dashboard serve as problem alerts. This low fuel warning is indicated by the light that resembles a gas pump. Electronic fuel system sensors that determine how much gas is left in the tank control this fuel light.

Most systems rely on an in-tank floatation device to gauge how much fuel is still present. The light turns on when the level at the tank’s bottom reaches a predetermined level. The gas warning light will turn on as soon as the fuel level exceeds that mark.

How Many Miles Can You Drive Once the Gas Light Comes On?

The tank isn’t always empty once the gas light turns on. Most vehicles will travel 30 to 50 more miles once the gas light comes on before the gas tank is empty. Depending on the size of the tank and the location of the low fuel threshold, each vehicle has a different range of travel time.

When the low fuel light illuminates, some vehicles, such as the Nissan Altima, can continue to drive for more than 100 miles, but F-150 trucks are only designed to go about 35 miles further.

You must determine the threshold that activates the light and the size of the fuel tank if you want to know how much fuel is still in your car. You should be able to estimate the number of miles you could still travel from here. The owner’s manual for many car models will also contain the precise distance.

Dangers of Driving With Low Fuel

Despite the fact that high gas prices are unavoidably annoying, you should never drive with a low fuel level because doing so can lead to a later repair bill that is even more expensive. Here are a few explanations for why you ought to refuel before your gas gauge runs out of gas.

1. Damaged Fuel Pump

Since replacing a fuel pump is typically not a straightforward fix, you should avoid dealing with it. But if the fuel level is low and the fuel pump starts to pump air instead of fuel on a regular basis, this can quickly cause fuel pump damage. Therefore, you shouldn’t make it a habit to drive until the fuel is too low.

The gas tank will likely need to be removed in order to replace the fuel pump. The fuel will also need to be drained, so you might prefer to take it to a shop for repairs, which will cost more money.

2. Excessive Engine Sediment

There is sediment in all gasoline. This is valid even if you are utilizing premium fuel from the best gas stations.

Sediment enters the engine when the fuel level is low. Additionally, when the fuel level is low, other deposits and debris may enter the engine. This is a major factor in long-term engine damage and would need to be replaced, which would be expensive.

3. Clogged Filters

The fuel filters also become clogged with the sediment that is entering the engine. Although you can replace the fuel filter, you shouldn’t replace unnecessary components too soon.

You will have trouble starting the engine once the fuel filter is clogged, and you’ll experience decreased acceleration. Additionally, it may lead to a rough idle and misfiring. If you are extremely unlucky, the lean fuel mixture caused by a lack of fuel may even harm the catalytic converter.

4. Fuel Injection System Corrosion

More condensation is possible as the fuel levels drop. Corrosion in the fuel injection system begins as a result of temperature variations and the additional moisture.

The engine won’t run properly if this happens. Repairs that could have been easily avoided could now cost you a lot of money.

Tips to Conserve Gas

1. Drive Carefully

Fuel is wasted when the driver brakes erratically or accelerates quickly. In actuality, you might be wasting more than 33% of your fuel efficiency.

It’s best if you drive cautiously, keeping your speed at a normal level, and braking gradually. This action improves your gas mileage while also making driving safer for you.

2. Maintain the Speed Limit

Your car uses more fuel than it should once you exceed 60 mph. In fact, for every five mph you go over this speed, your fuel costs could increase by $0.30 per gallon.

Driving within the speed limit is another way to save money. You avoid the potential for expensive speeding tickets.

3. Remove Extra Weight

Go ahead and unload any unnecessary cargo that you are lugging around with you. You lose 2% of your fuel economy for every 100 pounds of cargo you transport.

Keep a bin in the car, and after every trip, fill it up with the equipment that wasn’t needed. When the day is over, take this bin inside to maximize your fuel efficiency for the following trip.

4. Maintain the Vehicle

The manufacturer’s maintenance schedule isn’t just there to make money for the dealership. It is made to guarantee that your car runs effectively and that the engine is optimized.

You could lose approximately 4% of your vehicle’s gas mileage if it hasn’t been tuned up. A test for emissions might also come back negative.

5. Check Tire Pressures

You can increase gas mileage by more than 3% by making sure the tires are properly inflated. For every psi of pressure lost, underinflated tires significantly reduce gas mileage.

Read the label inside the driver’s side door jamb to determine the recommended tire pressure for your vehicle. Each month and whenever the temperature drops, you should check the pressures.

6. Use Right Oil

Although using the proper oil won’t significantly improve fuel economy, every little bit helps. Don’t substitute 10W-30 for 5W-30 just because it’s more convenient if your engine requires it.

You can also shop for engine oil based on brands that offer “Energy Conserving” properties on the Symbol for API performance. For even greater optimization, these oils have additives that lower friction.


Is It Bad to Drive With Gas Light On

The risk of debris and particles harming your engine or fuel pump increases when you are driving with low fuel levels. If your fuel level is low, there is a much greater chance that any dirt particles will end up in your fuel pump rather than settling at the bottom of the tank.

How Long Can You Drive on Low Fuel

The Low Fuel light doesn’t always mean the end of your drive because most modern cars are more fuel efficient than their forebears. In fact, you can still drive anywhere between 30 and 50 miles (at the absolute furthest) in order to find the nearest gas station.

How Much Gas is Left in Tank When Light Comes On

There’s no hard and fast measurement — each automaker turns the light on with different amounts of gas left in the tank — but a general rule of thumb is between 30 and 50 miles.
