"Still the best Water Fuel Kit in 2010..."

By far the easiest-to-follow guide we came across - our own experience says you should set aside maybe half a day to buy the parts and get fully installed.

This is the only guide that assumes absolutely no knowledge of cars. Impressively, our support ticket was responded to in under an hour (although it could take a little longer at weekends)

Best of all, the technology required is readily available and cheap - we were able to access all the parts needed for less than $40. Given that its proven to increase fuel efficiency by as much as 40% , you will recoup your investment very quickly.

Installation works with any gas or diesel powered car, van, truck or SUV. Aimed squarely at car "novices", and still our top pick for 2010.

April 2010 Update The simplest systems can be made for as little as $20. Many people are selling these completed devices for $300. That's a profit of $280 per installation. And these things sell like hotcakes, once your first customer realizes how much gas their saving they'll tell a friend, and another friend. As the word spreads like wild fire, you'll be installing as many systems as you want. Think of all the extra cash you'll make. Installing just 3 systems a week, you could make $3,360 per month, PART TIME.

The Verdict: Fast and easy setup; works for complete car novices; proven fuel savings of up to 40% - our top pick
