Grand cherokee V8 5.2 same mpg as the I6 4.0???

NOT True My GF has a 97 zj 5.2 and it gets 10-12 city 14 higway. On the other hand my 96 zj loaded leather 4.0 gets 15 16 city and 20-21 highway.

YMMV !!!!

I have a 5.2

I get 10 mpg on the trail. On a really good day with a strong tailwind I can get 14 mpg on the highway. It's a Jeep and I didn't buy it for mpg.

Most of the guys on nagca.com talk about better numbers, but I don't believe it.

I swapped a 5.9 into my 95 ZJ and am getting 15 city and up to 18 freeway. It does have a few mods that may be helping like the Kolak 3" cat & back exhaust, 52mm throttle body and ported kegger manifold.

wow, if ur getting 10 on the trail, id like to know what u concider a trail. I normaly get around 3-6 on a moderate trail, all this is according to the mpg readout in the overhead console.

Thanks for the info im not really trying to save gas, i bought a v8 grandcherokee for towing and heard about this. It looks like it depends all on the shape of the vehicle and how you drive.
Thanks again, John

I have both a XJ 4.ol and a ZJ 5.2L and with my driving the millage is close to the same 16-18.

The 318 kicks ass though, I love it.

Had a 5.2 zj before my xj and i got close to the same mpg as my buddy with a tj 4.0. both lifted with tires and what not. both stock gears and automatic

Truth is that your driving style and the terrain you drive on will make the difference in mileage from one poster to the other.

With the 5.2 the potential to burn more fuel is there no doubt, that don't mean you will though.

X2

My mother has a 97ZJ 4.0ltr anywhere between 20-23 on the highway. One of my friends has a 98 5.2ltr it gets anywhere between 14-17 on the highway. Now on top of that my mothers ZJ has pretty damn decent breaks, and handles like you would expect. My friends ZJ while the 5.2 has some of the shittiest breaks I've come across, and handles like a overloaded boat. Damn thing runs good though!

Baaaa.... I was just about to X2 this post. Till I realized I was the one who posted it!!!!!!

My 98 has ABS brakes, the first for me, my 87 XJ has standard brakes, the 98 seems shitty but I thought it was the ABS.

Handling wise new shocks and the 98 feels great on or off road.
