I gather that the practice of allowing an engine to idle for a few minutes before shutting it off is necessary only with turbocharged engines. The purpose is either to let the turbo spin down while it is lubricated or to cool down gradually from its super hot operating temperatures. I don't think it is necessary with a normally aspirated engine. Might be wrong.
