This worked exactly as advertised, much smoother driving without the changing from 8 to 4 cylinders and back to 8 again. I haven't driven much to tell the difference in mileage yet, driving to Florida in two weeks so will know more after that. I would expect oil consumption will go down as well. I would recommend this to anyone who has the fuel management system on their truck.
