How Long After the Gas Light Comes On: Find Out When You Should Refuel Your Vehicle

When your car’s gas light comes on, it’s a warning that you’re running low on fuel—but just how long do you actually have before you’re stranded? For most vehicles, the gas light typically illuminates when there are about 2 to 3 gallons (7.5 to 11.5 liters) of fuel left in the tank. Depending on your specific make and model, driving habits, and road conditions, this usually means you can travel between 30 to 50 miles (48 to 80 kilometers) before running completely empty. However, some cars may allow you to go slightly further, while others give you a much smaller margin. It’s best to consult your vehicle’s manual for exact figures. Regardless, consistently running on a near-empty tank can damage your fuel pump over time and isn’t recommended as a regular habit.

Tips 1:

As a designer, I believe that organization and planning go a long way—both on the road and in your home. Just as you wouldn’t want to wait until the gas light comes on to refuel, you shouldn’t postpone planning your interiors until the last minute. One way I recommend managing your space efficiently is by utilizing tools like a room planner to get a visual map and avoid running out of inspiration for your next project.
