Can't watch the videos, at work right now.
All I can say is it sounds like BS to me. Adding a pill or an additive to your gas tank will not increase mileage. The exception to that being additives meant to clean injectors, cylinder walls and ports from fuel deposits or carbon build up. These simply put efficieny near original levels.
Internal combustion engines are just oversized vacuum pumps with sensors. It monitors how much air is coming in and mixes fuel in the correct amounts to have the mixture as close to the stoichiometric point as possible. Once the engine is running the oxygen sensors monitor the exhaust gases and relay to the main computer (PCM) to increase or decrease fuel as needed for the amount of air being received. The Fuel injectors "pulse" a mist of fuel into the cylinder, more or less depending on the previous conditions and running of the engine (engine knock for example will retard the timing through the PCM and in most cases use more fuel.) Thats a quick basic rundown of how it works
So that being said, how does this pill supposedly work, increasing the oxygen levels of the fuel to burn cleaner and possibly have more oxygen in the exhaust gases? This is the only thing that comes to my mind.
Maybe it is an octane booster which would increase mileage slightly on maybe 50% of the cars and be detrimental to the other 50%.
If you can post more about its basis in science, labs, and fact I would love to read it.
