When gas lines wrapped around the block in 1973, American mechanics went to war against the gas gauge. Gene counts down the 25 most notorious gas-saving tricks of the crisis era: the ones banned by law, the ones banned by the EPA's own test lab, and the ones so good that modern engineers quietly built them into every car on the road.
You will learn why mothballs and acetone in the tank were always a scam, what really happened with the legendary 200 MPG carburetor, why the EPA tested over 100 gas-saving gadgets and found almost none that worked, and the truth about the dropped tailgate. Then the tricks that still pay: tire pressure, the trunk purge, the feather foot, and the 55 mph math. Plus the banned moves that came back as active grille shutters, start-stop systems, deceleration fuel cut, and the pulse-and-glide rhythm Toyota wrote into the Prius.
