    Works better than some other higher priced addidstives.

    I had been a long time user of Amsoil diesel treatment All in One for a while. Made a switch to HS EDT and saw immediate improvements in MPG and reduced regens. Figured would try the Gasoline Extreme in my 2013 Jeep Wrangler. Saw an increase in MPG after driving about 50 miles. Going to run this tank through and see what happens on the next.
