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.
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.
Tornado installed easily and improved fuel mileage.
My sister swears by this saying it absolutely works. She bought my dad one and he said he noticed a difference too.
