What M.P.G. does your Xj get?

[Jeepster19]

My 98 gets between 14&15mpg with 31.10.50's and 89 octane.This will soon make a change for the worse once I get my BDS 6.5" lift&33's on it.That's ok,it will look cool doing it&be very off-road worthy finally!Can't wait to get it stuck!!!:driving::thumbsup:

I am at about 7-8 inches of lift 285s a locker in the rear stock gears, I get around 14-16 on 91 octane.

[Mudderoy]

As low as 10.5-ish and as high as 12.6-ish All city.

[Dirt Dogg Rydas]

Just over 11 mpg with 4.5" lift, 31" tires and stock everything else. Good thing it's a trail only rig now but now I need to get a tow rig

Damn I get the same mileage!!! Our trucks must be twins! :smiley-laughing021::smiley-laughing021::smiley-laughing021::smiley-laughing021:

You guys might want to mention automagic or standard transmission. I think all the high milers are manual.

You could start towing it and get really high milage:D

[4.3LXJ]

I get 14 - 16 around town on a 7.5" lift and 31s with 4.10s Highway about 18 at 65. 10 mpg off road with a light foot.

[gary63]

Automagic 4.0 3.55 and 28" or stock wheels I have added and change thing
and check it to see what works and what dosen't and if it is worth the money and time.That way when I start to add a lift and gear and tires
also change any engin parts I know what might happen.

How about neutral down the hill, Does that count as good gas milages? :D

lol that's exactly what I got on a camping trip a few years ago. That was before going to the 4.56 gears too! :rotfl2:

This was doing a correction for the larger tires with my TI83 calculator.

I did not change out the speedo gear.

How did you manage to go up in mileage?What is your tire size,gear ratio,etc...:confused:

[prerunner1982]

Manual, stock, with 235s, 20mpg... just drive it like an elderly person.. keep the RPMs low.

The manually tranny&the tires seem to be the difference in mpg.Do you know what your gear ratio is?

[gary63]

it is alot of little thing, you have to pick the right tires.For a example hard thin byes ply tires get biter milage than wide sofe radiols. good bearings like hub,u-joints, axle and sutch. also good lube (oil and grease)Some is worth the money to do some are not. I have been checking my milage on the stuff I do so I can balens out milage and performens when I start to change my jeep.

[JENSSEN]

I never really measured or cared to be honest,... it gets me there regardless of weather, road conditions and does it safely,...

Now since this thread I get about 550Kms to approx $50.00 of fuel @92.9 cents / liter. It is a 1993 4.0 with 546,000KMS , 3:55 gears , 265 75 R16 Dick Cepeks with a 5 speed transmission.

[Tural]

ok, i measured it in my new jeep.
4.0 AX15, stock height, 30x9.5, no engine mods - about 24mpg on the highway. i've only driven in city twice so far and it was around 18 mpg in city.
