I have bought a lot of things on eBay but I must say that this guide proved to be the best value of all. Sometimes you bid and win something that sounds really good only to be really disappointed when you finally get it. Well, let me tell you something about this guide.

First of all, the seller (pwa4u) was not only extremely accomodating and helpful in answering all of my questions, but he got the info guide to me 2 days after I won it. When I read it, the stuff in it was easy to understand and seemed to make good sense.  But still I was somewhat skeptical. It seemed too easy, and I thought, "if this really works, how is it that more people aren't aware of it."  Well. I followed the guide's directions but was a little disappointed after going through my first tankful of gas. I only saw about a 10% improvement in gas mileage.

So, I emailed the seller and he emailed me back (within a couple of hours) and told me to make sure that my air filter was clean otherwise to be sure to replace it.  Also, to be sure to use the right proportions of the ingredients. So, I replaced the air filter and was more careful with the ratios the second tankful. It really did make a BIG difference. My normal 18MPG shot up to almost 24MPG on the second tankful (I had gotten about 20MPG on the first tankful).

The point is, get this guide and follow the directions CAREFULLY.  Again I'll say, "it's the best thing I've bought on eBay".
