How long can a 2007 Chevy Impala LS Idle
How long can a 2007 Chevy Impala LS idle on a full tank of gas?, If I were to
start the car and just let it sit there and run, how long before the tank would be
100% empty? I ask as I do ALOT of driving for work and want to know if I
would be ok to let it run all night as I hunkered down in the back seat for the
night.
