With the mileage all are reporting, I can't see how a Feather Duster or Dart Sport Lite with a /6 and A833 OD could come close to the advertised 24 mpg city and 36 mpg highway.
They didn't. I won't expound any further, but the slant 6 never got 30 plus. Somebody's poor at math if they say otherwise, I don't care who it is. They just are not that efficient.
