The Chevy now gets 12.2 MPG, a savings of 11%. Based on this, I’d recommend the Tornado.
We saw our Chevrolet Impalas increase 3 miles per gallon. Thank you.
Tornado installed easily and improved fuel mileage.
In my 40-years living the automobile service life, I can’t remember any automotive product that was so in-expensive and maintenance-free as Tornado and delivered such positive results.
My sister swears by this saying it absolutely works. She bought my dad one and he said he noticed a difference too.”
