"It must be true, I read it on the internet"

Listen to Pope, folks. Think about it. If it were as simple as a fruit jar and some hose, it would be a developed technology. There is no "forgotten patent", notice they didnt give the patent number. There is no miracle separation of water into its elements....it takes energy to do so. You will see an improvement in your mileage since installing snake oil products makes you constantly aware of your mileage so you drive more careful...which works.

These scams have been selling for years and seem to pop up in quantity when oil prices spike.

Tune up your car and lose 50 lbs at the gym...that will do a lot more for your mileage!
