Fuel dilution can be a real problem, it's not an old wives tale.

This is the main reason for running thermostats. Even with proper A/F ratio you will increase cylinder wear if you allow your engine to operate below 160°F. Wide temperature swings only make things worse all the way around.

If you only drive a few hundred miles a year, maybe it doesn't matter.

Personally, if I'm spending all this money on an engine (any engine), I want it to perform well and last as long as it can.

Tune on a chassis dyno or read the plugs and use a stopwatch.
