*Additional oil is required with auxiliary oil filter
systems. Make sure to add enough extra oil to fill the
auxiliary oil filter system. For LUBERFINER 750
systems, add 14 quarts (13.25 L).
**Verify oil level indicator after initial fill. There may
be some variation in the fill level depending on the
vehicle option content.
Extending the recommended oil change interval requires
the use of an infrared oil analysis program which shows
the condition of the oil and its additives. For more
information, consult your GM Truck dealer, who is an
R
authorized Caterpillar engine dealer.
