What's your gas Mileage/
« on: November 23, 2007, 11:15:36 AM »
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

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.

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...

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.
