Running on empty: Low gas in the tank can be costly
The gasoline acts like a coolant for the electric fuel-pump motor, so when you run very low, this allows the pump to suck in air, which creates heat and can cause the fuel pump to wear prematurely and potentially fail. The repair could end up costing a couple hundred dollars to fix—much more than the $4.00/gallon fill up.
Also, if there is dirt in the fuel tank, it could lead to blocking the fuel filter; again, another expensive repair.
Mine also does it. I think that's the whole point of it, to scare you into putting gas now.Bingle wrote:I think it's normal - mine does the same and scared the crap out of me the first time it happened.
