They normally take the vacuum line from the brake booster.

Re: Mileage Awful

When I got my 2006 Liberty about a month ago, the mpg made me nervous since I drive about 80 miles a day. However, after a bit of work, now it is not so bad any more.

On the freeway at 60 to 65 mph I see 22 to 23 mpg, town and country I am right around 17 mpg, in town somewhere just under 12 mpg depending on how many stop lights, stop signs, etc.

Anyway, I picked up several mpg by doing a spark plug change, cleaning the throttle body & pcv, transmission service, fuel additive in the fuel tank, and pumping the tires up to 35 psi. Truck runs much better too.

I have noticed that the mpg is real bad during warm up, first 5 miles really kills the average, after that it gets much better. Going to try some synthetic oil in the differentials next, and maybe an engine oil change too.

Driving technique does seem to have an impact on mpg. Accelerating at around 3,300 rpm up to cruising speed seems to work better than at lower rpm, but I am still learning and playing with that.

Anyway, bottom line is that it does not do much worse than my wife's turbo Outback, and that is only because it weights 2 tons and has all the aerodynamics of a brick, matter of fact, we call it "The Brick"!

Re: Mileage Awful

I traded my 2011 Patriot for my 2012 Liberty. I honestly can say from the minute I bought this thing, I couldn't wait to get rid of it ! I put a chip in it. It did improve the gas mileage a little bit. But after 15,000 miles I was still getting an average of 15 miles per gallon ! After a year of ownership I just traded it in on a 300 HP V6 Avenger. It gets 30 MPG, and I couldn't be happier ! I've had a dozen Jeep's and always been a fan. However with todays gas prices, I would avoid driving. That's not me. It's unfortunate that in this day and age they couldn't do better. Maybe that's why 2012 was there last year for the Liberty ! Brace yourself, it doesn't get better !
