Intelligent Oil-Life Monitor®
(Vehicles with a 3.2L, 3.5L and 3.7L
Engine)

Your vehicle is equipped with an Intelligent
Oil-Life Monitor that determines when you
should change the engine oil based on how
your vehicle is used. By using several

important factors in its calculations, the
monitor helps reduce the cost of owning
your vehicle and reduces environmental
waste at the same time.

The following table provides examples of
vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of
use.
