"I'm thrilled with SpiralMax. It is revolutionary! I'm a car designer by profession. In fact, I designed the Mazda RX7 sports car...., The performance of SpiralMax is stunning. I immediately noticed a significant increase in power and acceleration within the first few blocks of driving.....My RX7 used to average 200 miles range on a full tank of gas. Now it averages 250 miles on the same tank of gas. That's a full 25% improvement. I will recommend this product to everyone. It cam simply help the planet."
