I have seen your product around for sometime but figured it was nothing more than the stuff you see on T.V., which I have wasted many dollars on. Ive tried them ALL.
I have a 1999 Chevrolet, Astro Van with 60,000 miles on it and have gotten, almost every time, 16.7 mpg from the get-go. On my last oil change I thought, what the heck, I'll spend the extra $6.95 and see what happens. Well, having 2 cars, I thought I'd just use a half-quart in the Van and wait 1 tank before adding it to the car. Three tanks later on the van I have gotten 19.2 mpg on the highway and 18.8 mpg in the city (lots of stop lights, and 19.2). WOW, a product that does what it says. So it has paid for itself 177 times over? Can that be right? Let's see, 19.06 - 16.7 = 2.5 times 25gal times 3 tanks = 177. Well you get the idea.
Foot Note: The first time I started the van up, the motor sounded healthier. I knew right there I was on to something. It felt like I had invented the wheel. And to think I waited all that time to try LUCAS OIL. I hate to do the math on what I have lost not trying it earlier.
