Magnetic gas mileage extender
On a recent trip, a fellow RVer showed me a magnet that he says extends his mileage by 20%. I researched it, found many products, and many COMMERCIAL-STYLE claims, but, not convinced that it really works ...at least, not yet !
Has anyone out there used this item on a car or Motorhome and measured it's effects?
