Before we had ethanol laced gasoline, my coach, a heavy 1978 Royale with a
403 and 3:07 final drive would achieve a steady 11-12 mpg at a steady pace
of 60 or so. But, it wouldn't pull the hat off your head. So, I set about
doing some "technical enhancements", namely a 3:70 final drive, Doug
Thorley plated headers, carb enhancements as well as ignition recurve to
take care of the lean mixtures that the headers caused.
It then would run like a scalded dog, climb grades with any coach, and
still got 10-11 miles per gallon at 65-70 mph on regular non ethanol fuel.
Then came the ethanol laced fuel. Sad day in my opinion. My mileage
dropped to 8-9 mpg. No other changes.
When we crossed Canada coast to coast, they still had non-ethanol fuel
and my mileage on that trip went back to 11- 12 mpg.
So, don't blow no smoke at me and tell me that ethanol laced fuel is
good for me. Corn farmers get a heck of a subsidy for growing corn for
alcohol. Them, it is a benefit. You and me? Not so much. Rant off!
Stay well out there. Judy got her 3rd Covid shot yesterday. No ill
effects noted.
