Oh and another old article:
"Some folks at Shell Oil Co. wrote "Fuel Economy of the Gasoline Engine" (ISBN 0-470-99132-1); it was published by John Wiley & Sons, New York, in 1977. On page 42 Shell Oil quotes the President of General Motorshe, in 1929, predicted 80 MPG by 1939. Between pages 221 and 223 Shell writes of their achievements: 49.73 MPG around 1939; 149.95 MPG with a 1947 Studebaker in 1949; 244.35 MPG with a 1959 Fiat 600 in 1968; 376.59 MPG with a 1959 Opel in 1973. The Library of Congress (LOC), in September 1990, did not have a copy of this book. It was missing from the files. I bought my copy from Maryland Book Exchange around 1980 after a professor informed me that it was used as an engineering text at the University of West Virginia. VPI published a papaer. March 1979, concerning maximum achievable fuel economy. This paper has several charts illustrating achievable and impossible fuel economy. About 1980 I contacted the author concerning conflicts between the paper and documented achieved "impossible" mpg. The author said, "I will get back to you.". I am still waiting for his response"
This is not my writing.
