If you're driving a car with an internal combustion engine, you can technically drive as long as there's still some gasoline in the tank. However, it's not advisable to run your tank down to empty. Doing so could damage the fuel pump and cause other problems.
It's hard to say exactly how long you can drive on one bar of gas, since it depends on a number of factors such as the size of your gas tank, the efficiency of your engine, and your driving habits. However, if you're looking to eke out every last mile from your vehicle, here are some tips:
- Avoid stop-and-go traffic whenever possible. Idling uses up gas without moving you any closer to your destination.
- Keep your speed at a steady 55 mph. This is the most fuel-efficient speed for most cars.
- Don't use any unnecessary electronics like the air conditioner or heated seats. These can suck up power and decrease fuel economy.
Ultimately, it's always best to play it safe and fill up before you hit empty. Running out of gas is never fun, and it could leave you stranded in a dangerous situation
