lift and tires

What ype of fuel mileage difference are you all getting with the 2"-2 1/2" lift. :?:

I am thinking about but i do not want to sacrifce too much gas>

well there are a lot of variables when talking about this.
First, what tire do you want to run, and is a p rated or LT rated
Second, what and how much armor is on the jeep
Third, how much crap is in the jeep
Forth, any upgrades like exhaust and or intake and or chip.
Fifth, manual trans or auto

Now I have the 4 inch lift, 100 pounds in armor, 100 pounds of junk, a super 44 muffler, an aem intake, a jet chip, and a manual trans

All of my tires are/were LT rated load range D or E

My michelin LTX M/S's that I had ranged 18 to 19 city
The BFG TAKO's that I run most of the year now are 16 to 16.5
And finally my BFG KM'2's mounted on steel rims are 14 to 15

2" lift, 255/65/17 General Grabber AT2 tires, mostly highway driving (56 miles highway every day for work) I was getting high 16.5-17.5 MPG.

I installed a K&N intake and I'm always in the 18's.

wow you get real bad mileage with the km2's :shock:

I have over 700# armor, 3'' lift and 33'' bfg km2 and I still get 20 mpg ... highway at 60 mph :oops:

yeah all of mine are city mileage spec... I don't got on the highway much

My truck at work gets 4.5 mpg

There is no real way to answer that ... As digger said there are a lot of variables to take into count.

Highway driving can be deceiving based on speed, I usually drive 65-75 MPH on the highway.

Diggerfreek · **Posted:** Wed Jul 22, 2009 11:46 pm

75 to 90 here :twisted:

How can this be???

I get 17mpg as an average over like 6 months no towing and not much offroading and I am stock stock!!

I am not a lead foot and on the highway I go about 70 mph and sometimes 75mph

The only time a do push the gas a little bit more is when getting on the highway.

I don't know about Boblemoche, but Digger and I have 6-speeds which probably helps a bit.

Yes a manual should get more mpg. I never looked for a manual KK and I do know how to drive one. Although it seems like lots of trucks/cars that are manual get worse mpg than automatic. ie: the fj

hrogi · **Posted:** Thu Jul 23, 2009 11:21 am

umm FJ is a strange thing.

Most of the time mnauls get better gas milage rating vers the Auto.

4 speed Auto vers 6 speed manual. this is why..

If the KK had a 7 speed Auto things would be differant.
Also 210 Max HP sucks... this KK needed more like 250 to 300 HP with a good torgue curve to get this beast moving and stay moving.

But all that stuff cost more money.... oops waitt not much more...

I am getting 20 to 22 miles per gallon highway. Sounds like that lift really sucks gas.

RPM007 · **Posted:** Thu Jul 23, 2009 1:06 pm

My KK's computer claims I average 15.6 mpg stock. I do drive like a jerk though. I think I am more suited for a WRX than a KK. They should have put 5.7L HEMIs in our KKs. I don't even want to know what kind of gas mileage I'll get after a lift and bigger tires. Ignorance is bliss, I suppose.

hiram · **Posted:** Thu Jul 23, 2009 2:12 pm

my fuel light comes on at @308 miles. I get about 340 miles out of a tank if i stretch it.
when i pull the boat i loose about a 100 miles

Boblemoche · **Posted:** Thu Jul 23, 2009 6:33 pm

I have the auto trans and the manual fj get worst mpg because the manuals are always in 4wd and not the auto

just remember to figure the change in odometer reading with larger tires. There are many calculators on the net that will tell you the difference.

mine is mileage x 1.05 / gallons

now THAT'S something I never considered.....

With larger tires on lots of the KKs here (or KJ, or TK, or whatever)... how does it effect the odometer? When you go to sell the truck, after running 100,000 miles as per the odometer - how many miles are really on the motor/trans?

stumpjumper_09 · **Posted:** Fri Jul 24, 2009 10:34 am

I think that is where people loose alot of mileage. mine on the highway doing the math straight is about 16 to 17 but doing it the right way it is 20+

with my 33's I get 15% more real miles than the odometer says. not a big deal imho especially if you only have 31's
