If gas had been $1.10 a gallon when I first started driving, in 1971, it would probably have been the equivalent of $4 a gallon nowadays.
Funny, but I was watching a Three Stooges episode from around the late 1930s, where the Stooges were operating a service station. The gas in that short was priced at 30 cents a gallon--just a few cents under where it was in '71.
In the 1950s and 1960s Gas hovered around 25 to 30 cents a galleon with occansional(sometimes frequent) gas wars that dropped it to around 15 cents. Oh, for the good old days:)Of, course I was only making about 3 bucks an hour in 1962, but still I supported my family on it and my wife didn't have to work either.
Growing up in the '50's, Sohio (Standard Oil of Ohio, now BP) charged 29/9 for regular for so long that the price was painted on the signs. Removable/replaceable numbers were simply not seen. Plus, they gave you a free drinking glass with a fillup. Full service too of course, no such thing as self-serve back then.
