In the past I have done everything in the world possible to effect MPG's with my Jeep. I have had both very good and very bad experiences.
At this point in time I am having a bad experience. My average MPG is about 13. and that would be on a good stretch of normal "county" driving. In town it is not crazy to see 9-10, with best highway at 18.
In the past the combination of intake throttle spacer and computer tweaking has had the overall result of a bit more hp, a bit less mpg. Weight in a larger tire and lifting has added weights well to further decrease mpg's which negate the increase I gained.
All this being said; I have the number 6 plug that IMO does not seem to seat correctly by lack of distance it goes into the motor. Has been this way since purchase, i think someone cross threaded it. Can this effect MPG's a lot? or is this a negligible loss? And how much would lift and tire size increase actually decrease MPG's? These are the only thing that have been changed, really, and what else could be an invisible drag and decreas on MPG's?
I have done it all, back and forth, and twice, to get ANY results, so I don't want a stupid lecture on "look it up", or "jeeps... gas mileage... not why I bought it...", or "The computer resets and there's nothing you can do" I have been a member long enough to have realized this already. I'm looking at what is mechanically wrong potentially that I can address.
