Here's just one quote from this article
In 1933 Charles Nelson Pogue made headlines when he drove a 1932 Ford V8, 200 miles on a gallon of gas during a demonstration conducted by The Ford Motor Companies in Winnipeg, Manitoba using his super-carb system. In fact, many people attested to these mileage claims as The Pogue Carb went into production and was sold openly. However, one of the crucial factors of these systems is the use of "white" gasoline, which contained no additives. It was at this time oil companies started adding lead to the fuel. Lead is an anti-catalyst that rendered Pogue's carburetor as inefficient as a regular carb. In his Patent, ( found on page 32) it is obvious he did not understand TCC and in my research have found his system constantly needed readjustment and importantly got the fantastic mileage on wet days.
