Charley, most engine wear takes place during start up, when the working
parts/oil is cold. Once the engine has reached operating temperature,
engine wear remains the same regardless of engine speed. Varying engine
speed causes variation in operating temperature i.e. driving in traffic,
resulting in increased wear. When out in the country, with more or less
constant engine speed, wear remains the same irrespective of the engine
speed. Lower engine speed will result in lower fuel consumption, not
necessarily wear.

The major factor in engine wear is friction between the moving
parts.
The more times an engine turns over per mile driven, the more wear
it is
subjected to. Overdrives reduce the number of revolutions per mile
driven. Judicious use of overdrive will reduce engine wear and
increase
gas mileage.
There are some people who disagree, against all reason. Flame
suit
on.
