Sorry, I'm just sick of these posts. The people that believe this shit refuse to be convinced by anything other than "hard proof", that the various "gas-saving devices" on the market don't work. Meanwhile, not one of these scammers has ever provided "hard proof" that they work, or even run without harming the car.
Meanwhile, their websites and videos use the same kind of evasive wording and meaningless technobabble as every herbal viagra site in the world. They've been using the same pitch for fifty years, and in all that time, NOT ONE has ever been submitted for testing to ANY government agency or accredited testing laboritory.
NOT ONE.
Seriously, show one iota of rationality, people. I know it's a lot to ask, but come on...
