We all know our Jeeps get sucky mileage, and I bought this product hoping for modest improvement. Finally had a chance to do some highway driving after a few weeks of city only trips. First calculation was mileage improved about one mile per gallon under "normal" freeway driving conditions.(Read not creeping along,keeping up). Even at this level, that will be about $5 per tank in my favor. And it only " sounds tough" when I put my foot in it. Very happy with this mod to my JK U.
