Larry,
You have an influential member on your side in this discussion. None
other than John Twist.
He has postulated the argument that it takes a certain amount of
mechanical "effort" to run the overdrive, which may negate any mpg
savings and/or lessening of the wear and tear on the engine.
Not gonna' get in this discussion - just relating what I've seen John
mention in the past. Interesting thought, though. Generally, you don't
get something for nothing!
