What is a gas light?

There’s a good chance this term doesn’t need any explanation. Still, it’s always best we know what we’re working with. Here is the informal definition of a gas light.

Do you know that little gasoline pump sign that lights up when you’re low on fuel? That’s right, we’re talking about your vehicle’s gas light. Nowadays, gas light (or gaslighting) has something you’d call a slightly different connotation. It’s used to describe an action we won’t waste words on.

Anyway, when the gas light’s on, it signals your car has about 10-15% fuel left in the tank. The best thing you can do is to stop for gas at the nearest station. However, that’s now always doable; the gas station might be miles away. So, should one panic?

To answer the previous question: it depends on the type of car you’re driving. Some cars won’t have an issue running for a decent mileage while the light’s on, some will. To be more precise, the whole thing will depend on:

  • Your car’s gas (fuel) economy. 
  • The speed you’re driving at. 
  • The location (highway vs. city). 

Generally speaking, most cars will make it to the nearest station with consequences. If, of course, for some reason, the station isn’t 100 miles away or something. Let’s further elaborate on that!

How far can I go with my gas light on?

In other words: how far away can that gas station be? First thing first, we hope the lines above didn’t scare you. Always remember that a low-fuel light isn’t an immediate threat. It’s more of a warning. However, you don’t have an alternative except to find the nearest station.

Most cars will let you drive for about 30-50 miles (46-80 kilometers) from the moment the light turns on. Of course, this is just a cruel estimate. The number of miles you can cross spring low gas levels depends on your car’s model. To find out that number, consult your owner’s manual. Among other things, you’ll also see the type of gas your vehicle demands you use.

Choosing to ignore the warning isn’t a good option. Carelessly driving around with low gas levels can be dangerous. More precisely: it can result in premature harm to your vehicle’s components. Not to mention your risk of running out of gas in an area that’s a bit far from a gasoline station.

It’s recommended you consider the number of gas stations existent on your route. Unless, of course, you’ve got gasoline stored in your vehicle’s emergency kit. Then you’re alright!

Wait, will low-fuel-level driving damage my car?

Unfortunately, that’s most likely to happen if you continuously drive it on low fuel. Even though you can drive it on low fuel – you’ll probably experience some consequences. The main thing is: your fuel pump transports the gas to your engine. It’s the very same gas that keeps the pump cool & moisturized. When you’re driving on low fuel, the fuel pump could overheat & eventually fail.

As if that’s not enough, here’s another thing. Driving on low fuel levels enables various debris to “contact” your engine or gas pump. Any dirt inside your fuel will end up on the bottom of the tank. That’s why the same dirt’s likely to finish in your pump if the fuel levels are low. Keep in mind these are expensive particles of your vehicle to replace or repair.

Driving on low fuel levels, although not prohibited, isn’t at all recommended. If possible, avoid it completely! You’ll have a stress-free ride, and you won’t waste money on numerous repairs.
