V7sport73 Here in El Paso, the US Army did an experiment in conjunction with MSD ignitions. The experiment is what created and started the MSD company. To make a long story short. I have received first hand knowledge of the mysterious 60 MPG carburetor.. Yes you can get great mileage out of those carbs. But the trade off is power. They were getting about 60 MPG out of a Chevy Chevette. But the thing wouldn't go up a .5 hill and took 30 minutes to his 65 miles per hour. That is why the preheating carburetors were never marketed. The bottom line is that if you want power it takes a certain amount of fuel to achieve it.

RedWrangX ok i will settle this now, lol, jk. me personally i would not buy a jeep unless it was a stick. i feel better off road with one. whether rocking out of a rut or climbing a hill i just feel more in control. as far as the 4 vs 6 thing. in my opinion i would not buy a 4cyl jeep. they do not get any better gas mileage if you ask me. they have to work so much harder. my mother owns a 4 cyl auto i own a 6 cyl 6 speed thats where i am getting my info. from driving both. not just throwing some manly crap out there. i used her jeep for a trip to nh and it was awful. lol

Before I do that, I heard a random tip on saving gas mileage is like drafting bigger vehicles (like tractor trailers) like 3-5 ft behind them that way you don't have as much wind resistance against our "bricks on wheels". though a co-worker of mine shot that down saying that the turbulence from behind the truck will lower gas mileage and you have to be like extremely close in order for drafting to work.... help...
Omar, you are really getting bad advice from friends. Its like if you have to ask about fuel milege in a Jeep you can't afford it. There is no such device that will get you 30 MPG. And drafting a Big Truck is so dangerous I can't believe you even talked about it. I drove truck for several years and if I saw you I would pull over and let you pass, immediatly.

You have advice on 6 vrs. 4, aut trannies vrs. standard. Make you choice aligned with your purpsse of owning a Jeep.

Good Luck.

If you go on the principal that 2 car lengths is a standard safe following distance, I'd say 3-5ft is pretty dang close. Maybe this is just my jeep, but I don'tthink I could stop in time if i was 3 ft behind someone and they slammed their brakes. As far as mileage is concerned, I haven't found anything that's gonna give you outstanding mileage. I have the 2.5 4 banger and I get less than 20 mpg running tires that aren't very aggressive at all. I have 53k miles and pretty much a stock jeep, so I don't know what you'd do to get 'good' gas mileage in your jeep.

coolman8bc Like everyone else said, kinda depends on what you are going to be doing with it. I'd go with the 4.0 liter either way because the 2.5 L seriously lacks power. I can barely pass semi trucks on the freeway. Like khenderson said if you're looking to get 33's the lack of power in the 4 banger will become even more apparent.
01-08-2007 04:56 PM
Mike001 I have a 4.0L TJ and I just lifted it I have a six speed manual in it with 3.07gears (for now) I am running 33's and still getting about 17-18 mpg's on the highway. My buddy with his 4 banger, auto tranny screams down the highway trying to do 60-65 on a flat road with no head wind. I almost bought a 4 banger a few years ago and I'm glad I didn't. If you do get a 4 banger I would get a stick cause you will have less parasitic power loss. As far as rock crawling goes I just work my e-brake until the clutch starts engaging. But like khenderson said if your planning bigger tires and its a daily driver I would opt for a six.
01-08-2007 04:34 PM
khenderson as far as fuel efficiency goes, the six will be a better option if you plan to go to 33'' tires just because the 4 banger will have to work extra hard to turn them. so mileage will be bout the same between the two with the 4.0 having much more hp and torque.

as far as auto vs manual....i'm a 5spd guy. i've always had them and always will. that being said, alot has to do with the terrain you offroad in and your personal preference. alot of guys that rockcrawl prefer auto because you've always got that little bit of forward push. where as with a manual, you've gotta give it gas, drop the clutch, all while trying not to roll backwards too much. and also high rpms then dropping the clutch with 33's and a d35, you're bound to bust it.
if you wheel mud, i'd say 5spd, cause you need to keep your rpms high and your tires turning as fast as possible to dig and clean the mud, and auto's like to downshift out of the power band, but with a manual you can keep it right where you produce the most power.

those are my thoughts on the subject. hope that helps some.

What's the max I can get out of a 6 cylinder wrangler??

Isn't Auto Tranny better since it won't stall (or will have to be put under a whole LOT of pressure to stall)?

anybody see any good deals for a wrangler around the CT area?

My friend who's got a nice TJ that is currently under construction has told me some of the following:

1.) with the 4.2L YJ (I can't remember what years) there is some kind of special kit (for the carb I think..) that will allow for maximum effeciency (forgive my spelling...) up to 30 MPG!
But, Only for the 4.2 in the YJ because of the carb or something on it...

I can't believe this but if this is true I'm going out and getting a 4.2 YJ sometime soon. NOPE

2.) I'm looking to get a wrangler for a year or two now... the type I'm looking for is preferrably a TJ (I'll go with a YJ if I need to) with around 75k, Black or Red (NO WHITE.) I wanted the four cylinder because I thought it was more fuel effiecent but I keep hearing the six is just as fuel effiecent with way more power. Is this true? I want to put on 33" tires with like 15" off road rims and instead of a lift I want to put on those after marker fender flares that make it look like a lift (eventually when I get some more money I want a lift) To fit 33's on a YJ or TJ you would need some sort of lift, even with the aftermarket fenders, as the rear will need to be lifted to fit those correclty. Asf or MPG.. the 4 does get a bit better mpg, but the 6 has more power, go drive each and see what you like.

3.) I know manual is always more fun to drive but isn't auto better for offroad? either one is fine, its all about what you prefer.

you can email me if you guys need to: Omarkhan860@gmail.com

Thanks in advance.
See above in bold.
