Thought it was interesting. My concept of it was a little different but I understood the 30% less the 12 mpg the same car/motor/rear gear would have gotten with an old three speed, non lock-up converter,and square bore carb than the 17 mpg I got with my 509 powered overdrive, lock-up converter, Q-jet, 442 meant to me that every week when I went to the pump that $20 worth of gas would get me the same amount of cruising that $30 would have gotten had I not upgraded for those parts.
I also understood that the same 5 mpg going from a 40 mpg gas miser to a cheaper older 35 mpg gas miser would have only meant a 12.5% drop in economy.
Although for what its worth the greater engine life less repair provide by a 1/3 less rpm meant just as much to me as I don't like to spin a big journal big block hard continuously. Plus I like that it put less strain on the cooling system since the converter wouldn't slip going down the hwy.
