Mine did....I put the lift in and it went to crap as I was running no air dam or plastic thingy between bumper and grill. I had major hood lift and it was almost not drivable over 110kph.....I added I imagine close to 200lbs to the front...and all of a sudden I am getting crazy good mileage...better than when I was bone stock as a matter of fact. I am not basing this off of a quick glance at the computer either..I did a run yesterday that 4 hours in one direction just to get there and I could see how well my gas held up.....no more hood lift at all...and


And for the American guys:


Doesnt make any sense to me but I will take it!!!

 

OK, I can not speak for the lift you installed but most vendors' lifts get rid of the factory rake of the JK when you install it. This rake removal did two things you probably noticed:

1. The MPG went to crap
2. The hood started "bouncing" when you drove at higher speeds

That said, when you added the weight of that heavier bumper and winch combo on your Jeep, you likely gave it enough of a "rake" to restore some of that aeodynamics; thus improving MPG and prably getting rid of the hood bounce.

Take care,

The first pic shows you mileage in Liters per 100 Kilometers. The second pic shows you mileage in Miles per gallon. I bet this is where the difference lies.

 

WOW!!!!!!! I did not even notice that GREAT EYES ROBAR!!!!!!

What he said!!!!!!!!

 

I guess my eyes aren't that great.

 

Tsk Tsk Robar

 

Yes I realize all that what I am trying to say though is that after the mods my mileage got BETTER than what it was at stock.....that is the physics defying issue here

 

I think the gauge is sometimes wrong. I got 25 mpg out of a tank of gas with 37s/5.13..... with ONE tank ONCE. All my driving was HWY at 50-55 though so I thought... maybe, nah.

 

...I think cause we're paying in excess of $1.21 a liter.....lol....that's why you further......lol.

 

Is that how it works? Right on. I should be getting great mileage, too, then.
