This is stamped on the tank of an Australian-made Coleman suitcase gasoline stove: It reads: IMPORTANT Never Use Ethyl RDCPED Gasoline At least I think the letters say “RDCPED”. I am speculating that the “Ethyl” refers to a proprietary fuel additive for converting pure gasoline to leaded fuel (but I don’t really know). But I don’t have any idea about the letters below. Any help gratefully appreciated. Tony
Can you rub a pencil on paper placed on the letters? Ethyl also referred to Premium gasoline when I was a kid. Regular or Ethyl.
Before lead was common in gasoline, ethyl could refer to ethyl alcohol that was mixed in for rising octane and sometimes to stretch a limited oil supply - it has been a common practise again nowadays but is just named common or automotive gas today. Those fuels could be very volatile if pressurized and forced through a nozzle without burning off at once - could easily cause fireballs or explosions on some stove types.
@snwcmpr The letters are worn because of the way the tank had been transported it the suitcase. Cheers Tony
Not alcohol, tetraethyl lead as Tom pointed out. That was the early gas additive. The American version would read "White Gas Only". White gas was the term for gasoline with no additives, ethyl was the anti-knock, more expensive stuff.
