Have just made my 4th or 5th payment on my 2008 Grand Cherokee. It is a V6 model with the Rocky Mountain package so it sits a little higher I believe and has the extra roof rails so I would expect a little lower fuel economy, though it should be virtually undetectable on the averaging meter.
I just went over 5,000 miles and did the second oil change.
Anyway, at highway speeds of 65-68 mph I am only seeing 14.7 mpg (on a sustained 45 minute drive with even roads, for every ascent there is a comparable descent). Actually if I increase my speed via the cruise control to 73 - 75 mph then the same route I see slightly better economy of 15.3 mph.
In either case that is very disappointing compared to the numbers the factory/EPA projects for highway driving. The best economy I have ever seen on the highway was 18.3 mpg at about 70 mph even.
I know its a Jeep, but I went the "economical" way and got the V6 in mine as well. I was expecting 14-15 in the city and 18-20 on the highway. Pretty reasonable considering thats even under what the sticker projected and thats what my 4.0 WJ would get. I get about 11.5-13 in the city and 16-18 on the highway. Which is why in another thread I said that I should have just got the 4.7 with the dismal mpg I'm seeing.
Wow, that's horrible. We had a rental 3.7 Laredo one time when ours was in the shop and we were getting 18-19 with city/highway driving.
The funny thing is: Our CRD's sticker says 17 city 22-highway and we get 25 highway and 20 city!
yes, mostly its possible to make round 20 mpg in the city. i do from 18 - 20 in the city. it depends on driving habbits. and range for hwy is 23 - 28 mpg.
22 - 23 i get when cruising at 100mph. and when i drive furious from 100 mph full trottle to max speed, little braking and again, (car chase with other cars) i get just 20 mpg highway miles.
We get better than sticker with our '08 Overland CRD too!
We get 11.5L/100km vs. the sticker shows 12L/100km (a lower L/100km is better) - all City. As a bonus, diesel here (Calgary, AB) is barely more than regular gas ($0.01 - $0.10 more than reg gas). I find that driving style doesn't impact the CRD's mileage as much as it does in gas vehicles...not sure why, lower rpms maybe? For the size/wieght/class of vehicle, the CRD WK mileage is unbeatable in the domestic car market. I praise diesel to anyone who listens!
I've heard the new VW Jetta 2.0L Diesel (same common rail technology as the WK) will get 5L/100km; I know what my next commuter car will be... Forget hybrid, hello diesel!
