I'm sorry, but perhaps you didn't learn the definition of 'anecdotal'.
Anecdotal (adjective): (of an account) not necessarily true or
reliable, because based on personal accounts rather than facts or
research.
So, before you attack my statements as ridiculous, consider what I
wrote. My *anecdotal* experience is that the overdrive does nothing
to improve gas mileage, but does significantly improve the
enjoyability of driving at high speeds for long distances. In fact,
my overdrive-equipped MG gets *worse* mileage when compared to a non-
OD equipped car with the same driver (as I wrote previously, I
suspect other factors are involved). As a second *anecdotal* note,
when my OD was inoperative, my mileage on a 180 mile trip from
Ellensburg to Pullman was still right within the range I normally get
(26-30). I noted it only in that there was no change to note.
Your mileage may vary. Mine didn't.
