I stand corrected on the "kit" comment, but I stand by my other statements. I was reading about the kit on Marks4wd and forgot about the whole Australia thing.

I didn't say he would get 17.8, I said someone got as high as that. I used a gain of 3mpg, [color:"red"] NOT 5MPG [/color], (re-read my post) to figure out the savings. I was also just pointing out an economical way to get to part-time 4WD, a way that could net you some decent savings easily. I realize that's not the best way, but pointing out it's possible, trying to give some options rather than just saying NO it's not worth it. Is that alright or am I doing something wrong by doing this?
