I believe that two things happened at the time - 1) Manufacturers of gasoline had to add more expensive additive to bring the octane up and 2) Engines were redesigned to work on lower octane. The first accounts for the increase in price.forrest":17qzgg1v said:A friend of mine worked in the petroleum industry as a chemical engineer when unleaded gas was being introduced. Unleaded cost more at the time. I asked him how leaded and unleaded was different. He said, while turning his hand clockwise, we just shut the valve off that adds lead to the fuel. I asked him "if you are taking raw materials out of a product which costs you less to make, shouldn't it cost less to the consumer since it costs you less to make? Why are you charging more for unleaded?" His reply was "because we can".
That information is available many places online - for example - here.cruiserlessvinny":3vgmraxt said:I've wondered what the cost of gasoline is as it relates to inflation from some of the earlier time periods being discussed. 20 cents a gallon sounds cheap until you realize that it was common for folks to make 50 cents an hour in 1947.
