Hi All,
I can also confirm the bad fuel consumption on these !
I had a loan when my Grand Voyager 2.5 CRD was in for a major service.
Gues what....the grand voyager with the old engine returned low to mid 30's and the Cherokee with the auto box (2006 model) was low 20's !!!!

that's the VM POS engine again....I can also confirm the bad fuel consumption on these !

the Merc 3L is a good engine, just not very economical (as dismals go)
I used to run Jeeps all the time, went though 15 of them over the years, but NEVER had a dismal, only 4L then 4.7L petrols.
I ran a 55 plate Grand Cherokee with the Mercs V6 for 60,000 miles
My work is mostly distance but I don't hang about, average mpg on the trip computor was 32.9 but this is US gallons and the Jeep was chipped
Chipping gave me 10% increase overnight as well as close on 280BHP and a mountian of torque
This equates to close on 39 UK MPG!!!!!
Keeping the tyres at the right psi, servicing and using fully synth, got a 2.5t 3.0L V6 diesel up to the high 30's
The dash read out is in US MPG and most seem to forget this simple fact
I now run an 08/08 Alfa Romeo 159SW with the 1.9 JTDm diesel and I am going back to a Grand Cherokee asap, not becasue the Alfa is bad, far from it it is a good car, just not big enough and no auto gear box or decent cup holders!!

Thanks for all the good advice. Calculated actual MPG based on a full tank using plug in sat nav to check distance and got 28.8 over a 3 day mixed run. Much happier The dash read out is showing 19.6 mpg! Guess it's either faulty or screwed!
Well 19.6 MPG(US) is about 24 MPG(Imperial), so there's still a significant discrepancy if it were using US gallons... oddnav18tor said:

Are you sure that was US Gallons? Even 32.9 is good - 39 would be amazing.Bear in mind that chipping also messes up the mpg computer (it doesn't measure MPG at all, it calculates it from injection cycles with a known quantity of fuel injected).

Have just got hold of a 2.5TD Old shape cherokee
I thought it was a renault lump?
not expecting great shakes in fuel consumption, but given the 4.0 would return mpg in the teens - it shouldn't be quite so thirsty...
No, it's a 2.5 litre Italian VM lump. And you might get 25mpg. the pisser is that at 40mph (a lot of my commute at the time) you're right between 2 gears. Any kind of need for power in the high gear and you're buggered, but you're revving it's tits off in the lower gear.I thought it was a renault lump?

This is my second Grand Cherokee with the Mercs V6 Diesel motor and I love them as they seem to suit how I drive and the roads I drive on
All local work this weekend, and am showing 27.5 mpg on trip which = 33UK mpg
