Fuel economy from Grand cherokee laredo

[tga_4x4]

Are they really as bad as people say ?? I have an Au fairmont wagon and people say my falcon would be way cheaper to run, so to all the people who own such vehicles please advise me so i can be more the wiser

Hey,
I used to have an XJ Cherokee and would get about 5k/l round town and between 7 and 10ks/l on a long steady run depending on how much I pushed it.
The Grand Cherokee is a bit heavier so you might struggle to get those figures I guess.

Cheers.

I had 4L ED sw, had exactly the same economy as the two XJ's that came after it. I had done Hamilton to Whangarei and back on a tank (to the poing the fuel light would come on as I hit hamilton), they weighed the same (1400kg) and had the same fuel capacity, or near enough to anyway.

The latest trip from Mitimiti on the West Coast of North Hokianga back to Hamilton was 570kms, that was done with 70-75 litres in my Grand sitting on 33's and stock diff ratios and a fair bit of extra weight that consisted of winch, bars etc, fully loaded with camping gear inside and towing a small trailer also fully loaded. I was more than happy with the fuel numbers.

Compared to some other 4x4's (diesel esp) the numbers wont set the world alight, but comparative to the ED I was driving it was spot on the same, so the numbers become relative. If you're driving a prius about, then the comparison is horrendous.

"People" often say lots of things that "they" know f-all about.

so they dont sound as bad as people say, I am looking at a 96 laredo with 164k , kinda like the way they look

What sort of mileage do you get out of the Fairmont? My old AU Fairmont wagon would never better 10l/100km. Yet my two AU sedans could get 7.5l/100km and my AU XR6 ute 8.5l/100km, so a bit of varience of fuel figures of all the coons I've owned and I don't know why.
All were better than my two XJs though, which managed 10.5 on a trip driving very conservatively. Can't imagine a ZJ would be much different.

[tga_4x4]

My fairmont wagon get2 around 9.3 pussy footing it from tga to auk and back around town is around 13.5, my sedan was getting 8.5 tga to auk and back

Do the Grand jeep Cherokees have a fuel computer ??

SO TRUE,I wished i never listened to the bull shit people said about jeeps,i should of had one years ago..the best 4x4 i've owned by far and so what if you use a bit of fuel ..f**k i love my Jeep [ Wrangler ]...opps not sure if any of that is relevant ....lol..

Do the Grand jeep Cherokees have a fuel computer ??

Dunno quite what you mean by "fuel computer" but they have an ecu that regulates all the settings for throttle body, map, cp etc etc that can be remodelled. Ive just put a chip module into mine that has reset the factory numbers.

I think i will take the plunge and get the grand cherokee after all

I think i will take the plunge and get the grand cherokee after all

one failing before taking the dive is the transfer case... awesome while theyre going good, calamatous if it fuks out. Ive removed mine and popped an XJ 242 case in (which loses the fulltime fwd too)

are those transfer cases easy to come by ?? should improve fuel economy also being 2wd selectable over all time 4wd

[yeti]

i got two in my shed,,,,but im down here in shake shake land

[xj]

easy enough, but needs to be post '97. the pre 97 had input shaft length of .75 inch and speedo wiring in a different place/configuration to the post 97 which also has the .840 (from memory) input shaft. The 249 has the .840. Its only a very small difference in measurement, so i dont know if it really makes that much of a difference, but I chose to match like with like.

Jury is out on the fuel economy thing.. I think its minimal.

Sorry to hijack thread (but i think its safe to say a 4.0 coon will be cheaper to run), what is the difference in the ZJ and XJ transfer case? And will the post 1997s bolt straight up? I ask as i'm looking at a ZJ this w.e for maily off roading. Cheers.

Phew i am looking at a 96 Laredo, just because they are not as square...

Was referring to the pre and post 97 xj cases. the ZJ 96- 249 have the same input shaft length as the 97- xj 242

XJ transfer case (242) is selectable 2wd, 4wd part time hi and 4wd fulltime lo, ZJ case (249) is 4wd full time hi and 4wd full time lo and has a viscous coupling hooking it all up together. When in full time 4 lo it transfers power equally to all 4 wheels and unlike conventional systems, it doesnt try to get all the power to a wheel with no traction, it continues driving the ones on the ground, effectively acting as a centre difflock.

Additionally, while at it, ZJ's dont have LSD's (or one that Ive ever heard of anyway, there may be some, Jeep have never been consistant with their standards) as some seem to think, XJ's (some) do.

There's a ZJ for sale at the mo in the Bay of Plenty that would seem to be a good buy.

some 4.0l coons may be cheaper to run (as in fuel) but mine wasnt. My current 6.0l VE runs cheaper than the old ED did.

EDIT: also need to mention that if fitting a 242 case, the front drive shaft will need to be fitted as the stock ZJ ones are cv jointed. An XJ front driveshaft will bolt right on in there.

[tga_4x4]

This is going to sound stupid whats the difference in zj and xj, can you tell i am a jeep newbie..lol
So a 96 Laredo a good choice, dont want hard core 4x4 as it will be a daily driver..

Thanks for your reply and yep that is the one in the BOP I'm looking at lol. Owner reckons its an LSD in the rear (or is it a viscous set up like the WJ?). From my understanding of your post the ZJ transfer case doesn't offer a 50:50 low range lock like the XJs. As you said there is a bit of confusion after doing research on the ZJs as Jeeps 4wds systems get branded a different name every year while being an option on all models at the time. Seems no two models are the same lol.

xj = cherokee (nz versions in sport or limited, 2.5 l diesel or 4l petrol) square looking brick, in bulk in nz between 93-2000 models
zj = grand cherokee (laredo, limited, orvis and tsi variants in NZ, 4L only) larger, rounded, 96-2000 (i think they stopped in 2000)

Id take the BOP one at that price, if thats what youre into. Gimme a call if you want, I'll help wherever i can.

The main reason i removed the 249 was the previous owner had fitted a lockrite in the front, and with fulltime 4wd that aint fun, especially when cornering.
If you were to get it, and you have issues, ive a spare 249 here that would cost ya f-all.

Thankyou thats clears it up alot...what are yours like fuel wise , realistically my coon usually eats around 60 per week in fuel just going to work and back, usually around 125km

http://www.trademe.co.nz/Browse/Listing ... =364176273

[xj]

yes that one.

i cant really comment on economy outside of the numbers i posted up the ohter day, I dont use it as a daily driver (i have a work vehicle) and have never really bothered looking at the numbers. Its certainly going to be easier on the gas on a long trip than buzzing about town.

Also, the 33's suck some power out. Ive got 4.10 R and P to fit to regear the diffs, just havent gotted about to getting them in yet. Theyll pull the power back to the ground and get it pretty much back to stock. The white one in the above pic is on 31's with the 249 case, hes had it for about 8 years and it performs real well in the sandy stuff and is more economical than mine by far.

meh, stock ones are a dime a dozen. the 165k kms seems to be the norm for the era. Id grab the maroon one.

Cheers for all your input, will let ya know what i get, the blue one i can get for 4k still leaves me with a few bucks for wheels..
The maroon one is very appealing but wants extra for the big wheels..

[coop]

Thanks for your offer xj, will keep it in mind, although it looks grouse on 33s, providing i buy it I will probably take it on 31s as you say the 33s will take a bit to turn and she'll be blowing CVs and snapping axles left right and centre lol cheers.
