So far so good. I went on a 200 mile trip with a full tank of gas and got 24.2 mpg. Not bad for a full time 4x4.

Read that works best if used with premium fuel, have ran premium in it the whole time I've owned my jeep. It does actually work as advertised. More power across entire RPM range, has increased my mpg by only 2 though nut still an improvement.
