Is there something wrong with a company finding a cheap way to do something. We all benefit from efficient ways to do things.

Lead additive (tetraethyl lead) was discovered by a fellow name Midgely and another fellow working with him, a Mr. Charles Kettering of electric starter fame. They were trying to find ways to keep fuel from detonating. After about 20,000 formulae, they found that very small amounts of this additve did the trick allowing for higher compression and more powerful engines. This was done in GM labs so that the Army Air Corps could hop up aircraft engines in the 1920s.

Sure, prices went up when lead additive was banned. In order to attain the anti-knock rating that lead additive achieved, the refiners had to tinker with the octane/heptane polymer chain mix. This required the addition of more specialized equipment at refineries. No doubt many contracts were let to mechanical contractors to install the new equipment and to tear out the unneeded leading systems.
