Dropping MPG
 
Hi all, after purchasing the '04 GC I posted about a few weeks back, I
was initially thrilled with a combined fuel economy of 22 MPG !

However now that the temperature is starting to drop here in the
frozen north, I am somewhat distressed with the current 14 MPG.

Nothing has changed, my driving habits, routes and distances are the
same, the only change has been the outside temperature.

I am thinking that I may have a sensor going a bit flakey.
Anyone have any thoughts ?


BTW 4.0L, 4 speed auto, 3.55 rear

How are you computing your MPG?

Are you using the same flavor of gas? Might the fuel blend have changed?

If you were using real gas and switched to some kind of alcohol blend
that's going to drop your mileage.

Re: Dropping MPG
 
With the 4 liter in a WJ you should be averaging overall between 18 and 20
mpg if you are a conservative driver.

Are you figuring your mileage with a pencil and paper or the EVIC?
