How far can you actually drive on empty?
We all know that feeling, you're driving down the motorway and the fuel warning light comes on. Do I risk it? There's a fuel station right there, but I'm in a bit of a rush and I think I can make it.
What should you do?
Well lucky for you the internet appears to have an answer.
According to this rather helpful chart, you can expect to get anywhere from 30 to even 108 miles on an empty tank. Of course, the actual numbers will vary based on how you drive, your car's condition, and several other variables, as a result Your Mechanic do emphasize that these are all just rough approximations.
Why does my car lie to me?
Almost all automakers are quite conservative with the fuel light to keep you from getting stranded, which makes sense. You'd be pretty pissed off if the car ran out of fuel within seconds of the light turning on. Preempting people to pull over and fill up stops bad press story and ticked off customers.
