Back in the early 2000`s they had a bunch of commercials about the Tornado fuel saver. I never really thought anybody bought them. Changed the filter on the Expedition today and saw this sticking in there. I know for a fact it don`t do a damn thing It might get 15mpg on a good day
Also found that the filter had not been changed in 8 years! Part of it was my fault, never made my grandparents get it checked and when I "inherited" it I`ve been doing routine maint. on it.
