I picked up a Jeep Grand Cherokee with the 6 (trying to do my thing for the planet). The hype and the sticker said I should get 30 MPG HWY and 22 City (Imp gal). Well on the HWY if I keep it under 110KM, a speed so low it can get you killed on the 407, without AC, I can get 23 mpg. In the city, I am taking it very very easy and getting 16 MPG without AC. It is disappointing to say the least. Can anyone explain this major discrepancy? I believe HWY is measured at 55 MPH or 89 KPH but how different could my “easy” city driving be.

 

Some companies inflate their numbers a bit, jeep being one of them. If you were expecting mileage out of a jeep, with respect, you should return it. lol

I have a 2010 Focus that gets 46mpg average city and highway which makes up for my miserable 12mpg that I've had at BEST in any of my jeeps.

 

Most vehicles still need a break in period to get close to the mileage that they claim, I would wait till it's time for the first oil change and if it hasn't improved by then I'd be saying something.
30mpg in a Jeep sounds like responsible goverment, not going to happen in my lifetime.

 

maybe you bought the Hemi by mistake.

 

yeah you're absolutely right. it might be a mistake. so sometimes we must be careful in picking up things in order for us to be sure off. like what we are doing in our jeep liberty parts or in our car. right?
