Just curious what everyone is getting for gas mileage with their setups...
I have:
- RE 62 mm throttle body
- Airaid TB spacer
- Aftermarket header
- K&N FIPK and air filter
- Dynomax muffler
- MSD Spark plug wires 8.5mm
- MSD Coil Pack Blaster
I'm running 31" tires with 3:55 gears in an automatic tranny.
Currently I am getting 400 km to a tank (70L) of regular octane. I am switching to 4:56 gears in a couple of weeks, so it will be interesting to see if there is a change. :D
-
-on my XJ with 33" boggers & 4.10 gears I can still get around 300Km on a 60L tank!
-on my stock ZJ I'm getting over 650Km on the highway on a 80L tank and the engine has over 360K on it so pretty dam good if you ask me!
-
In my YJ with 33s and 4.10s I am getting about 375-400 km on 75ish L tank. I have a high flow dynomax exhaust as well and a manual tranny. 4.56s might be a little steep for 31s

4:11 w/ 33's
went to waiporous last weekend, there and back plus about 2 hours total wheeling, drove this week. filled up yesterday $47.50 @ 97.9
ODO was 350km. that woulda ran me outa fuel before i cleaned my K&N
-
I'm getting about 450-75... but my tank is a bit bigger (more than 70L)
-
Drivin a lot more highways lately. 475-ish kms/tank on 89 octane.
Really depends on how heavy my right foot is.
29' AT's @ 3.07 gearing.
K&N "Big Gulp" intake system.
Airaid throttle body spacer.
Thinkin of opening up the exhaust. Not sure if that will help much.
-
2 stats:
XJ, 4.0L, auto, 3.55 - 400+ in town, and almost 700 highway. 30x9.5 BFG AT's.
TJ, 2.5L, 5 speed, 4.10's - 350 in town and about 425-450 highway. 33x12.5 TRXUS MT
By the summer of next year, both will be on 33's and regeared to 4.88:1.
-
I'm getting 500 kms per 50 L tank
I guess that is why I bought a Mitsubishi Pajero eh???
33" bfg AT's
4.88 Gears LSD F&R
No lift

Just curious what everyone is getting for gas mileage with their setups...
I have:
- RE 62 mm throtle body

- Aftermarket header
- K&N FIPK and air filter
- Dynomax muffler
- MSD Spark plug wires 8.5mm
- MSD Coil Pack Blaster

Are all those upgrades worth the time and money? Is there a noticeable difference in performance?
Thanks,

Talked to Bill and he agreed. The Stock rubi's come with 4:10's and could stand to be lower.
Stock TJ manual = 29's w/3:07's
Stock Rubi manual = 31's w/ 4:10's
-----------------------------------------------------------------------------------
Stock XJ auto = 29's w/ 3:55's
My XJ auto = 31's w/ 4:56's
Make sense? I also confirmed this with alot of people on NAXJA. Plus, I will be towing with it, and may upgrade to larger tires in the future...
-
2.5L TJ rubi springs (net 1" lift)
30x9.5 bfg at's
K&n Drop in filter
4.11/4.10 stock gearing
Regularily get 17mpg (US)
About 400 km per tank to the fuel light.

I'm almost embarassed to reveal my gas milage , that and I've never figured it out.
My Comanche 2.5 / 5 spd / 4.10 gears / 31's , lame on power , fuel economy sucks.
94 YJ 2.5 / 5 spd / 4.88 gears / 33's / 4.0 throttle body / flowmaster muffler / electric fan , good power for a 4 banger , pretty good fuel economy. ( next to the 4.88's , the electric fan was the biggest improvement )
88 YJ 4.7 stroker / 5 spd / Banks header / Comp cam / ported / roller rockers / RE 62mm throttle body/ Banks full exhaust / MSD wires n' coil / 4.56 gears / MTR 35's or 36" Iroc bias ply depending on destination.
VERY powerful , best torque at low rpm , mostly stop n' go driving so fuel economy sucks , on the highway it gets good milage. Sadly this one only likes premium . It is capable of lifting front tires on pavement if done correctly though not recomended ( AX-15's do not like shock loads) , I believe this transmission is at it's limit for maximum input torque.

91 yj 4.0 HO....4.88 gears,35'' tires....4 miles to the gallon(as long as I go easy on the go pedal) :)
-
350 ci, corvette on 33's with 3.54 gears and i dont want to talk about it............lol, not sure but im saying 250k a 50 ltr tank of 89 octane
-
355CI SBC 4:10's 29" Tall Tires goes through a half tank driving accross town.. on 91 octane (altho not a jeep) haha
-
4.0L HO, ax-15 5-speed, 4.10 gears, 33" MT/R's, electric fan, ditched the cat and added a hi-flow muffler, just weighed the jeep at 1820kilograms with me in it and half a tank of fuel, full hard doors and hard-top installed... and no im not really fat. but i figure i get about 500kms to a 72litre tank.
the muffler helped a lot, the electric fan helped a lot as well. i dont have a fancy intake or TB yet. eventually would like to get the newer style intake manifold, a hesco 68mm TB and a hi flow intake. maybe a chip and bigger injectors... apparently Uni-chip has a new plug in computer for the 4.0L that can be tunable. and painless wiring is designing a stand alone fuel managment system.

4.0L w/ 2.5" Exhaust, Dynomax Muffler, MSD 6.A Digital Ignition, MSD Blaster Coil, MSD 8.5mm Plug Wires, Bosch Platinum Split Plugs, K&N FIPK, 62mm Throttle Body, 31" lift and running 245/16's. Just put in 71.67L (really rean it dry) and there where 388.4km on the od. Wow, my mileage sucks for a 4.0L, then again, I let it warm up forabout 5-10mins in -20...

31" lift eh? That's huge :P !

Wow, my mileage sucks for a 4.0L ...
31" lift will have that affect.
-
My smart car gets 420 kms on a 22L diesel tank :) (65-70 mpg)
-
Geeze...if you're driving it, it must be called a smart a$$ car.... :roll:

OK then. So I took out the 28" blocks and 28" coil spacers (jackasses) :roll: , so I'm at around 3" of lift w/ 31's that measure around 29". The mileage seems to have improved this tank. I'm at 360km and still have 1/8th of a tank left.
-
$50 to fill up today @ 97.9
200KM.
too much idling, especially @ bowness park
-
33's around town I get 14 miles/gallon
on the highway I would expect better numbers using 5th and all ...
-
If I were to run my tank dry, be getting almost 500kms out of 60L of gas. Is that reasonable :?:
-
Seems kinda thirsty for a sewing machine engine... :lol:
-
I'm getting 24mpg while towing a trailer with 2 quads at 110km/hr with my 3/4 ton Dodge Ram Cummins Turbo Diesel. :wink:
RACKMAN
-
stock ZJ with 5.2L (29" tires and 3.73 gearing) and the K&N FIPK i got 29 - 30 on the highway. goto edmonton on quarter tank. (80L tank) city was round 500.
now with the lift and 33s, mileage in city is the pits, maybe 12, and highway is still decent, get bout 400 - 500 to a tank, depends how much of a hurry i'm in :wink:
-
Around 10l per 100 km.
Diesel Defender, mostly stock, 32" tires.
-
Stock Rubi -
16L /100km
14-15 mpg
360'ish kms per 60L fillup
-
93 ZJ 4.0L 4.88 gears 9" lift, 35-36" tires 11-12mpg city and approx 14-15mpg on the highway. That works out to about 320-340km per tank city(80litre). Not too bad all things considered.
-
1983 CJ-7 258 ci 6 cylinder, T-5 with 2.73 gears and 31 inch mud terrains.
Traveled 6000 km last September and average 21 mpg NOT using overdrive
good thing cus I only got a 12 gallon gas tank
-
21 mpg is awesome
Me ? , fuel economy is at an all time low , been running tires that are nearly 37" tall for a few weeks , speedo accuracy is questionable too.
35" MTR's going back on till the ground thaws.
