This is a 137-page book I wrote after realizing that compared to everyone else I know, I get rather extraordinarily good gas mileage. I see an average improvement of nearly 40% gas mileage (over $1,250.00 per year that stays in my pocket!) by following the simple secrets and tips found in this book. You can too! It's not even difficult. You would have a hard time finding all this information in one place anywhere else, too. This is more than fifteen years of experiments, discoveries and research I have done for maximizing my gas mileage. The information in this book will pay for itself in no time - possibly even before you finish using your next tank of fuel! Useful tips whether you use gas or diesel, ride in a car, truck, van or humvee, or you use a 2- or 3-wheeled vehicle.
