Great fuel milage with Prolong

I’ve been using prolong engine treatment for years and it has helped me to achieve a cleaner interrior engine, and better fuel milage. it may have reduced wear, but i have not proved that with an engine tear down to measure the parts. what i am excited to tell you about, is that with my ’08 4 cyl fusion with the 5 speed automatic, factory tires, and at 90 degrees ferinheight, 43 mpg is expected regularly. you may know that the car when bought new was expected to get 28 mpg with a maximum of 32 mpg (according to the epa mandated sticker.) sometimes the car gets as much as 52 mpg(this higher milage is achieved at 45 mph and often with whatever wind there is at the back of the car, blowing to the front of the car.)   i’m getting 37.5% or better mpg.
