[prewett]

gasoline -> gas at least has a certain logic to it, even though "gas" is unfortunately already a word that means something rather opposite. "Petrol" has always seemed strange to me, too, though, since nobody pumps black sludge ("petroleum") into their car but rather the clear, fluid petroleum distillate called gasoline.

I got curious, and "Gasoline" apparently comes from "Gazoline", which Samuel Boyd used to avoid trademark infringement with Patent Cazeline Oil (for use in artificial light), which was named after John Cassell. [1]
