"Nikken Magna-Charger improves gas mileage".  The paragraph below describes a product called a Magna-Charger and many distributors don't mention this product during a regular presentation; we do, however, because we use a Magna-Charger not to magnetically charge water coming through our water line but to improve gas mileage in our Saturn Vue. 

Nikken Magna-Charger

Focus-Field Technology is an innovation in magnetic engineering. The concave shape of the powerful, neodymium and ferrite magnetic inserts on the Magna-Charger provides a better fit for pipes. The facing magnetic surfaces are opposite in polarity — this creates the Focus-Field effect, in which the magnetic flux lines are directed at right angles through the water flow. This product may be ordered through your Nikken Distributor.

Now, I have no scientific study or official numbers; I have only our experience with this product and our personal results.  Prior to our cross-country trip we installed a Magna-Charger on our fuel line.  It's easy to install and does not have to be installed professionally. 

Prior to our trip our 6-cylinder 2003 Saturn Vue averaged 19-20 miles per gallon around town and up to 25 miles per gallon on highway/freeway trips.  When I say our car was loaded down for our trip, it's no exaggeration!  We looked like TV's Beverly Hillbillies Clampett family loaded top-to-bottom with gear; including a roof-top carrier!

We averaged close to 30 miles per gallon on our trip with the Magna-Charger installed and since we've been back in San Diego and driving around town in an unloaded vehicle we're averaging 25 miles per gallon.  We've spoken with other Nikken Distributors and although the results vary, they've all noticed an improvement in miles-per-gallon in addition to a more efficient and cleaner-burning fuel.  Given the cost per gallon of gasoline (which is now back up to $2+ per gallon), we are pleased to save money while improving our carbon footprint.  If you're interested in this product, please contact us!
