Sorry for stating the obvious, but wow, 11 MPG is pretty poor.Originally Posted by YotaFun
Even in the dead of winter (-30C) when gas mileage is as it's worst I get around 14-15 MPG I will sometimes get as low as 12-13 MPG if I'm using the car starter and idling the truck to heat it up before the kiddos go to daycare in the morning.
Like I said though, be methodical about solving the issue you'll have your epiphany moment soon enough.
