Run Your Car On Water (yep, that's what it's literally called) is the second most popular course online, behind water 4 gas. There are a lot of differences between it and other courses.
Ease Of Use: 
This course is really pretty straight to the point, and easy to read. It's a little different to water 4 gas. It comes to 115 pages in length (at least when we brought it) and is basically in a number format -- completely step by step. Also, all the paragraphs in the book are only two or three sentences long. This makes it really easy to follow.
Value:
The Run Your Car On Water course is almost half the price of Water 4 Gas, at least for the time being (the current price is $49.97). However, at just over a hundred pages, it doesn't have anywhere near as much stuff. It just doesn't have the kind of bonuses that water 4 gas has. When you think about it, though, this doesn't matter so much. As long as the guide allows you to run your car on water -- WHICH IT WILL -- you'll make back your investment back several times over in the form of gas savings.
Support: 
A support email is offered. There is no knowledgebase and helpdesk like water 4 gas has.
