V6 vs. V8

im in the market for a '00+ Jeep Grand Cherokee Limited 4x4 and was wondering what the pros and cons are for each engine. Now i know that the v6 has significantly less HP, but the mpg is higher than the v8. Can someone let me know what is recomended. thanks

If you ever plan on towing anything I would go with the V8. The acceleration is great around town also.

Look at the fuel efficiency carefully -- the difference is very slight. Definitely go with the V8.

I have a ZJ 5.2 V8 with 105,000 miles and it gets 14 in the city and 17.5 on the highway, despite the lower reading that the trip computer gives me. That's about the best you can expect from a pushrod V8 moving that much weight. My brother in law has the I-6 and he gets as good as 21 on the hwy, and I think about 16 in the city, but it's a dog compared to my V8. The V8 in my 69 Mustang get even worse mileage then my Jeep, so I don't complain too much; I'm used to bad gas mileage.

One kudo for the I-6 however is that it is very easy to change the sparkplugs, wires, cap, and rotor. I changed those out on my V8, and it was difficult to get to everything.

Yeah, the older 5.2L got poorer gas mileage, but I bet it's worth it. We like our GC -- the six is seriously very good for a base engine -- but I'd swap for a V8 any day.

He's looking at around a 2000 model. The mileage difference between the 4.0L and the 4.7L isn't significant enough to choose the six over the eight.

Am I the only one who loves my I6? I have a '92 wrangler and a '96 GC limited, and I love the 6, lots of torque, good gas mileage, and very, very reliable. We put a lot of miles on our jeeps, and the gas mileage helps. We also regularly tow a boat 40 miles each way, almost every weekend when the weather is warm, and don't have any problems with not enough power.

I love my 6 too. Just did a tuneup the other day and it took less than an hour and as far as power goes-it moves pretty nicely.

my ZJ 5.2 litre v-8 has gotten me up to the 190k miles mark and still going. I plan to get well over 200k.

If you're getting the limited, you have the option for the High Output 4.7 V-8. 20 hp more then the regular. I think its cool, my dads car has it

As far as I know, I'm the only person to own a flame red liberty with the light bar, and until someone disproves that to me, I'm going to enjoy it.

When I bought mine I looked at getting the 6. The gas mileage wasn't that much better to justify getting the I-6. I have the 4.7 V8 and it gets about 19 mpg. Not as good as my Honda use to get but I like the Jeep a lot more

I have experience with most of the Jeep Engines. I have a 98 Wrangler with the 4.0L, love it for that. My brother had a 98 ZJ with the 5.9L, killer engine! My dad is on his second WJ, first one was a standard 4.7L V8 (great performance), now he has a 02 Overland with the 4.7L HO, very very nice. Jeep did switch to a V6 with the Liberty, 3.7L just a V6 of the 4.7 V8, i prefer the I6.

Go with the V8, preferably the HO. That's my .02.

What liter V8's came with the 93 and 94 Grand Cherokees? I am looking at selling my Cherokee for a GC. How reliable are the V8's? My mom has the 5.2 liter in her 98 and I love it. Also anyone who owns a 93 or 94 with a lift and tires or even stock, could you post some? thanks -BB
