FFi MPG Caps Tested by WSAZ-TV News Channel

[Abreen11]

There is no way any 'magic pill' can improve your fuel consumption. These pills and almost all other 'fuel saver gadgets' have been proven to give no mileage increase when tested under ideal conditions. You should always remember that the people in this video are only news reporters told to say what they are saying, not impartial experts in testing whether anything they are promoting works or does not work. Don't be scammed, ask an expert such as someone from your local motoring organisation

It's a scam people MPG can vary daily it would take long term testing under "ideal" conditions to prove anything for all we know the weather and speed were factors what about the fuel itself? My car sometimes averages 28mpg sometimes it averages 32mpg and yet I always go to the same fuel stations and I drive the same way IE highways at 60mph the fact is there are millions of products out there that claim to work and most either do nothing or only slightly improve mpg's or worse damage the car
