Increased the mileage by 2 –3 miles per gallon!

I have installed the DieselMaxx/GasMaxx on Ford Crown Victoria’s, Dodge Charger Hemis and Chevrolet pickups. We have increased the mileage by 2 –3 miles per gallon. The most notable change was the performance. The hesitation was eliminated and the acceleration performance increased. I installed one on my Crown Victoria. I noticed the difference immediately when I accelerated. The maintenance division has removed the spark plugs for inspection. The plugs are carbon free.  When we retire a high mileage unit, we remove the DieselMaxx/GasMaxx and install it on the new unit. We will continue to install the DieselMaxx/GasMaxx on our fleet.  Jim Elliott , Chief of Police, El Campo Police Dept.
