Researchers: Leaded Gas Responsible For Crime Wave

Leaded gasoline was invented by General Motors in the 1920s. Tetraethyl lead was a cheap octane booster and antiknock agent. It prevented exhaust valve and valve seat wear and allowed much higher engine compression. It also could have been the cause of the big post-war crime wave, researchers say.

SPPPP Vibrant color 9 times out of 10 for me. There may be a few shapes that look just right in metallic gray, for example. There are a few nices ones out there. And I like VW "White Silver". But I'd usually prefer a deep red or a vibrant metallic green. Or a bright blue.
