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"!
