The increase in the price of fuel in recent years caused a proliferation in the number of so-called fuel savers on the market. These products promise to help reduce fuel consumption simply by adding them to your vehicle’s fuel. Sold in liquid or solid form, or sometimes as a device you attach to your engine or other important mechanical component, these systems simply do not work and sometimes can even damage your vehicle.
Over the years many publications have testes fuel saver products, and have come to realize that most have absolutely no impact on fuel economy. A small percentage will enable very minimal reductions in fuel consumption, but that often comes at the expense of increased emissions.
Moreover, many companies that created fuel saving products have been found guilty of false advertising and banned from selling their products. Examples include:
BioPerformance – a small pill that was banned by a court in Texas in 2007.
Fuel Saver – heavily fined in both Canada and the United States for false advertising.
PVI – fined in 2002 for false advertising.
Econopro – banned from the market in 2006 for creating a product that had no effect whatsoever on fuel economy.
Ultimately, reducing fuel consumption depends on your vehicle’s technology (hybrid, electric, or simple more fuel-efficient than its competition) and your driving habits. Making sure your vehicle is properly serviced is also very important.
