I just put one on my jeep. Along with new o2 sensors. Before I was getting almost 21mpg at times(17-19mpg was average with some playing around), and it then went to as low as 12mpg.
Only 70 miles into this tank of gas, which is the first one with the cat. I should report back in a week or so if I remember. I am going easy on it, but did notice some increase in power, although that could be because my cat and 02 sensors were bad.
