I mused about this at church a while back, and it re-occurred to me this morning. A very large fraction of people I know refer to decaffeinated coffee (and sometimes to decaf tea as well) as "unleaded."

This slang usage appears to have come into being in the late 1960s or early 1970s, when unleaded gasoline entered the market as a result of anti-pollution legislation. By the time my child was born it was nearly impossible to find gasoline WITH tetraethyl lead in it. Thus, my generation is the last in the USA to have actually encountered leaded gas. My kid's generation seems to have picked up the usage... but I wonder just how we'll manage to explain the term to the babies of today once they're old enough to ask.

I encountered "leaded" gas as recently as the early '90s... My brother and i were sharing one of those '70s boat-like cars and each expected the other to put gas in it. Needless to say, we ran out and had to call AAA one day. The next day smoke started pouring from the back seat while we were driving... The local fire department ripped it out and it turned out that the catalytic converter had overheated and started melting the bottom of the rear seat, The overheating was due to the dodgy gas the rescue truck had used the day before -- it seems catalytic converters can't handle leaded gas!

Good frickin' grief!!! We'd known about that problem for at least 20 years by then; catalytic converters were the reason USA automobiles *SWITCHED* to unleaded gas back in the 1970s. (US based manufacturers started with the 1974 model year.) That fire was lawyer bait -- actionable negligence on the part of the rescue truck. I'm glad you all *survived*!
