WARNINGS
Do not handle a hot oil filter with
bare hands.
Continuous contact with used motor
oil has caused cancer in laboratory
mice. Protect your skin by washing
with soap and water.
If your vehicle is equipped with a diesel
engine, an Intelligent Oil Life Monitor™
calculates the proper oil change service
interval. When the information display
indicates: OIL CHANGE REQUIRED, change
the engine oil and oil filter. See
The engine oil filter protects your engine
by filtering harmful, abrasive or sludge
particles and particles significantly smaller
than most available will-fit filters. See

the Intelligent Oil Life Monitor™. See
Engine lubrication for severe
