mileage truth
 

I am looking at purchasing a 4 cylinder TJ, for other reasons as well but with the price of gas these days, Mileage is important to me. I have read many reviews. Some are good and some are not. What is the truth? What can I expect from TJ in mileage (stock because I want the best mileage).

Re: mileage truth
 

I have a 03 tj 6cy manuel, originally stock, the mileage was good as expected speed limit on the roads, no jack rabbit starts, mostly highway compared to my friends gutless 96 yj 4cy manuel we were very close to the same mpg. I wonder why anyone wants to buy a jeep if he never intents to run it offroad. You want great mpg buy some small foreign car and make 40mpg plus which u will never get with a jeep. I cannot compare now as its modified and my mpg suck, but that was my choice. For long trips your not pushing the pedal all the time to keep it rolling at the limit and that extra is there if you need it for passing or emergency.Your choice Good Luck

Re: mileage truth
 

4cylinder, to 6 cylinder is virtually the same mileage. If you want mileage, buy a Neon, or a Civic. You will not be happy with a JEEPs mileage. For fun factor, you can't beat a JEEP.

A jeep has the aerodynamics of a brick ....

I commute 150km daily in my 99' TJ with the 4.0L. Sucks gas like a pig ... but I wouldn't trade it for a thing.

Re: mileage truth
 

my 97 with the little 4 banger auto is great on gas, until I go off road or tow my boat or drive like a maniac( which I do sometimes that's why I bought a Jeep) and compared to my 86 oldsmobile it is by far 3 times better on fuel.

Re: mileage truth
 

Of Course like some have replied to me, if I was only interested in mileage I would be looking at a neon. I want to play also and already have a use for a 4 X 4. Presently I have a pickup but find I don't need a pickup that bad. Think a utility trailer would haul grass clippings to the dump once a month.

Re: mileage truth
 

We weren't atytempting to be rude, JEEP culture as a whole knows that JEEPs don't have good mileage. If you are used to full/mid size pickups, then a JEEP is in line for you.

Re: mileage truth
 

its about 11.5 liters /100kilo on the highway and 15.5 liters /100 kilo in the city .Averagem of 400kilo each tank

Re: mileage truth
 

the 4 Cyl manual Trans. is not too bad on gas - And gas is still so cheap in Northamerica, that I don't even think about it.

Re: mileage truth
 

My 98 Sahara has an inline 6, I'm lucky to get 300 kms per tank and I drive like an old man.(I think the tank is 49 liters)

Re: mileage truth
 

I don't know about the highway/city figures, but I have a 4 banger with a 5 speed and a 19 gallon tank and I get over 400 km per tank easy.

Most of my driving is city but I try to shift in a sensible manner and drive pretty reasonably most of the time. 2200 to 2500 RPM is my sweet spot for cruising, 2400 to 2900 for shifting.

"Mileage may vary depending on use":)

Re: mileage truth
 

Compared to my old full size chevy 4x4 my Jeep gets good mileage even with the lift and bigger tires..

Re: mileage truth
 

I think it depends on your driving style... and gas is $0.665 here so it has come down a LOT lol

Re: mileage truth
 

I have stock '04 LJ 6 cyl, 4L - 15 L on hwy and up to 30 on 4wd snow in city, and around 22 regular city 2wd drive. i never go over 2200. So i think its not too bad.

Re: mileage truth
 

03 Rubi with 285 MTR's and rarely get above 15mpg

Re: mileage truth
 

I ended up getting 2 tanks right at 535K to the tank on my way out to New Brunswick, that was to the low fuel light....
cruise was set at 115, and a couple spills at 140, and got it to 182kph for laughs...
and of course going thru some mountains.

Re: mileage truth
 

nice, i'm lucky if i get 300 km from a full tank lol

Re: mileage truth
 

yea im starting to think that my mods have helped, the only thing is i wont notice it until i go on a long trip that kills the majority of the tank, cause i have a heavy foot around town for sure... lol

i blame it on the extra power

Re: mileage truth
 

You do know this is the TJ forum, right???
From what I gather, throttle body mods are virtually useless for TJ's and K&N filters rank right up there with the worst possible mods ever. But that's just me. I'm glad you noticed that huge increase in horsepower lol.
Sorry man, but nothing beats good maintenance and sensible driving as far a mileage is concerned.

Re: mileage truth
 

sorry for a bit of off-topic, but I would like to put a different spin on mileage truth - I've never seen TJ with more than 160 000 km on it, is it maximum it can go?

Re: mileage truth
 

You really need to get a grip on reality. My 98 is at 160K and running like a champ and looking pretty good too if I say so myself. Here's a picture and there's more in my gallery.

Ya gotta maintain it if you want it to keep running. Sometimes you need to drop some dineros to replace rusted out fenders and a few other worn out components like I'll be doing soon. You can't just beat it to $hit and expect it to last. That goes for pretty well any vehicle.

I expect to hand this one off to my daughter when she graduates from high school. She's in grade 5 now, and I'll be driving it every day between now and that fateful day. Maybe she'll inherit a classic

Re: mileage truth
 

i am definately not a model driver :D i have an 04 TJ Rocky Mountain 4.0 with a 5 speed stock as of yet, and i average 400 km per tank with about equal highway to city driving

Re: mileage truth
 

I have friends who have had the 4.0 go over 400,000km before a rebuild was needed.

Re: mileage truth
 

My 4.0L TJ on 33's was getting the same milage as my 2.5L TJ on 32's was which was about 380 km.
The 4.0L is on 35's now and I get about 280 km to a tank. The 35's make a drastic difference on milage and power with the stock gears.

Re: mileage truth
 

as most people have been saying,jeeps don't get that far on a tank of gas especially
lifted and bigger tires etc. etc.but if yous must know lucky if i get 325kms .

Re: mileage truth
 

I installed the Edge Trailjammer Kit on my 4.0L and there was a substantial improvement in both power and milage. Gained about 50 km per tank. Ran it that way for a year then put on a Magna Flo Cat back on it and that really worked with the Throttle body mods.
It goes like it's on 33's

Stock Throttle Body at 58mm vs a 62mm Throttle Body... You're gonna get a power gain.
Can't say much for those throttle body spacers though. Had one on my old 2.5L TJ and I notice a slight increase in throttle response but it had no effect on milage.

Re: mileage truth
 

I would never go for the 4 cyl my friend has it and has to down shift alot on the highway just to try and keep it at 110km it really sucks for him he really wishes he bought a 6cyl

Re: mileage truth
 

The 2.5L is not fast, but it's more fun than a barrel of monkeys once you get it off the highway.

And 110kph should be no problem for a 2.5.

Re: mileage truth
 

Putting on a High flow Magnaflow cat and muffler tomorrow, that will be it for the uncorking process, Airaid intake, stainless headers etc, I will let you guys know if the mileage changes.:3gears:

Re: mileage truth
 

There is more power at the wheels for sure WAY MORE!
