As far as prelubing the engine before start up goes, do you
really care that much?

I do. Race mechanics do. Aircraft mechanics do. The US Navy does.

Listen to an engine upon startup with heavy oil in it (even at summertime
temps) and hear all the grinding and banging and clattering going on inside the
engine for the first ten or fifteen seconds, let the engine warm up a couple of
minutes, shut it off, restart and listen again.

If you can't hear the difference, replace the battery in the hearing aid.
