Ok today I decided to run my tank as close to empty as possible.
I have a 16 gallon tank.
The car said 5 miles till empty and then I filled up.
The car took 14 gals to fill.
Is there 2 gallons in reserve so when the car says empty you really have 2 gallons left
or should I have my car rechecked. Its a new car 2012 V6.
