I’ve learned that many people are skittish about flushing practices and even periodic oil changes. This fear seems to be driven, in some cases, by an unsavory past experience or alarming anecdotes passed on by others. The story usually begins with a seemingly healthy machine. As a preventive maintenance measure, the machine is scheduled for an oil change or flush. Immediately afterward, the machine fails. The quick conclusion reached is: Flushes and oil changes cause sudden-death mechanical failure.
