OUR TOP PICK -  Water For Gas

 The critical element that  comes with chosing a gas conversion kit is to find a manufacturer that offers an EASY and SIMPLE kit, with INSTRUCTIONS on how to install it, saving you time. 

This kit used parts that were redily available, and cost less than $30.  I increased my Nissan’s fuel efficiency by 116.8% seeing an increase in power and torque. With this kind of increase in MPG, the system pays for itself in couple of weeks. We saw an increase in MPG of 40%, but Water4Gas mechanics tell us they have seen higher increases- up to 90% if you have a mechanic change the settings on your engine.

This kit is great for beginners, and would work on any car, truck SUV.  Installation took just part of the afternoon, and the benefits were immediate once the kit was installed. 

This company had excellent service, answering my emails within 30 minutes.  Their kit also had more than double the output of HHO (oxyhydrogen), of any comparable design, which is so important in getting fuel savings.

Their system is proven, simple, and even a beginner could install it.  Additionally, there’s peace of mind because it comes with an 8-week money back guarantee.

Update: Run Your Car On Water is Running a Promotion, temporarily offering their kits  for $67 instead of $197and includes 5 free bonuses. The price, I was told will shoot back up to $197 soon.

In Summary: Quick, easy to follow instructions, proven results, and obvious increases in fuel economy make us choose this product over the other fuel conversion kits out there.

Gas Conveter is our #2, and is one of the oldest in the industry. While I use the system in my #1 pick, our testers found #2 to be useful and effective as well.

The great thing about our number 2 selection is the bonuses it comes with - They include a guide on how how to make money installing these systems for others and tips on how to get IRS rebates to pay for your installation.

I’ve been asked that with all these benefits, why did we give this selection the number two spot?  Our answer- the second system isn’t as easy for a beginner to install as the first one.
