Lubrication and Filtration—Another Key to
Longevity
Lubrication is a major key to extending the life of your car. It’s so important that
you often hear it referred to as “cheap insurance.” People have a lot of questions
on this topic. What systems and parts of a car need lubricating? Car manuals

between these two? How reliable are oil life monitor (OLM) systems and how
