Yea, my MW3 came with AEV front and rear bumpers a warn 9.5 cti, tera flex BB and 305-70-17 nitto terra grapplers, an airraid CAI and a fancy rear view mirror with reverse camera sunk into rear bumper. I think everything else is stock rubicon. I am happy with my town mpg really and will be heading to SLC next weekend so I can test the highway mpg. Honestly I am happy with evreything and plan to only make it worse with offroad upgrades down the road but since the wife wants upgrades that up the mpg I figured I'd research a little and see if I could make this a win/win situation. One that I'll wait and see on is a Tuner system for the 2012's 3.6L. I doubt that I will do headers and full exhaust system, at least until I require a high clearance setup. One thing that bugs me is the 1st owner did do alot but the dealer did not give me any breakdown of what was done so I have no idea if it was re-geared at all and what other small changes may have been done. Oh well break it and upgrade right?
Can't remember where I read and I don't know how true it is but I heard the general rule is a loss of about 1 mpg for each basic upgrade. Bumper + winch = -2 MPG. Really not sure how accurate that is but sounded good at the time. Tires I'm sure can count for more, so to get 15-19, I think you're doing pretty good. I'm basically stock (Tires,bumper at least) and I am around 16.5 average, mostly stop and go. I've seen it as high as 20 after some steady cruising, but it drops pretty quick. But I wouldn't have it any other way. :yup:
Is your number based on the computer or do you calculate it?
Guess I'm pretty lucky, the only thing my wife insisted on is a sweatshirt in the Jeep because she thinks "it might get a little chilly in the winter", said while running doorless. :clap2:
