TJ mileage
 
As of last week I am the proud owner of my first-ever Jeep! 2005 TJ. I absolutely love it :punk:

However, the gas mileage is a bit of a shock :eek: I'm getting about 320kms (200 miles) for a full tank. That's roughly 57 litres or 15 gallons of gas.

Is this normal?
Thanks!

Thats pretty low mpg for stock. I get 15 to 17 on 31" tires

Superkill 05-07-2012 05:36 PM

2005 tj x no lift no tires, 87 octane I get about 200miles per tank. 91 octane about 210 miles per tank lol

Jonny15 05-07-2012 05:38 PM

Thats about 13 mpg...not good but nothing alarming either deppending on your setup. What size tires do you have? How many miles? 4 or 6 cylinder?

For what its worth i usually get between 16 and 17.5 mpg with my 06 6 cylinder 64,000 miles driven mostly on the highway.

Is it okay to put 91 in a jeep?

Absolutely 100% useless :)

All octane does is prevent detonation (preignition of fuel before the spark plug fires) in higher compression engines. The 4.0, 2.5, and 2.4 are NOT meant to use 91 octane. It can actually hurt performance by delaying ignition.

Use 87 octane all day, everyday!

Aerodynamics of a brick wall.

Redsand 05-07-2012 06:14 PM

I get 12 on a good day

Jwood621 05-07-2012 06:34 PM

I'm getting around 15 on the highway with 32" M/Ts

Rwilliamjacob 05-07-2012 06:39 PM

jeeze i get 300 miles out of a tank with 32's thats all highway though, if i just drive around town and highway its like 236 i think the last tank was. stick shift rubicon

I-Want-A-Jeep 05-07-2012 06:40 PM

I last checked at about 14mpg. I drive only in town - eg: A full tank took me almost a full 3 weeks to go through..

04 X 5spd 4.0 33x1250's

ntemerario 05-07-2012 06:42 PM

I get about 14 on my 06 x with 33s. Get gas about every 210 miles or so.

Rwill8751 05-07-2012 06:44 PM

Its better than my truck so I'm not to worried about it. But I would say i get about 17mpg

Are you filling the tank, recording the mileage, running the tank low, filling the tank, recording the mileage. Recording the number of liters/gallons to refill and dividing that number into the number of miles/km driven between fill ups.

BLK00TJ 05-07-2012 08:06 PM

I'm getting 18-19 on my '00 with 4.25" lift and 33s. I realize that I don't have a race car so I drive like an old fart and block traffic.

VA Jeeper 05-07-2012 08:13 PM

Im getting 31 mpg ,,,,,,LMAO just kidding. The two times I checked I was getting 17.1 MPG out of my LJ.

tk9805 05-07-2012 08:14 PM

I have 31's with no lift and get around 17-18mpg, but I get to use cruise a lot because my drive to work is 90% highway driving. I would love to put a 2" lift on, but I'm just worried about how far that would cut into my mileage. Still thinking about it though, but I'd have to put bigger tires on too.:facepalm: One thing leads to another...

That's about what I get but I see ALOT of stop n go driving so that kinda kills my mileage.

I had that same problem so I changed my work hours and route to keep from all the stop and go. It sucks leaving for work at 5:30 AM but I don't get tied up in rush hour traffic. Even if I leave at 5:45 I'll catch the start of the rush hour here.

baldbilly 05-09-2012 02:56 PM

Thanks everyone! I appreciate your responses. I have oversized tires (not sure how big - I will check) so that's probably affecting it. I will start following close behind big rigs on the highway to save fuel!

just filled up on the way home-21.4, actually think that's the highest i have ever gotten. just normal driving around town and to work-actually a mix of city/country road driving.

ednayn 05-09-2012 04:45 PM

1997, 2.5L, 5 speed, 235 75/R15's. All stock, although I think the stock tires were 215's. Had it a month and am consistently clocking 19 mpg. As low as 18 if I drive hard and up to 20 if I drive easy. Happy :)

The Tonk 05-09-2012 04:48 PM

Last tank was 268 miles and filled up 17 gallons. That's 15.76mpg on 35x12.5 and a 6" lift. Time for a tune up maybe?

TJRubi 05-09-2012 04:52 PM

Just did 150 miles down and 150 back on the interstate (doing a dog rescue transfer) overall average was 18 mpg running 73mph. 4.0 auto 5500+ foot altitude (we lose about 15% power) and stock 16" wheels 265 70 tires at 35psi--FWIW.
