SECTION 2 – REQUIREMENTS FOR FUEL, ENGINE OIL, AND COOLANT
NOTE: Mineral and synthetic oils are acceptable for use
provided they meet the API category recommendations and
ambient temperature guidelines.
API CJ-4 oils provide protection against the following:
•
Catalyst poisoning and particulate blockage
•
Engine wear
•
Piston deposits
•
Soot related viscosity increase, deposits, and wear
•
Viscosity loss due to shear
•
Oxidative thickening
•
Oil foaming and aeration
API CJ-4 oil, in combination with Ultra Low Sulfur Diesel
(ULSD) fuel [0.0015% (15 ppm) maximum sulfur content],
is recommended to maintain performance and durability of
aftertreatment systems meeting 2007 and beyond diesel
emission regulations.
API CI-4 oils are allowed in diesel engines that meet these
regulations.
Use of the CI-4 engine oil shortens Diesel
Particulate Filter (DPF) cleaning service intervals.

SAE OIL VISCOSITY GRADES AND TEMPERATURE
RANGES
The Society of Automotive Engineers (SAE) defines oil viscosity
(thickness) by grade. Colder temperatures require lower grade
oils for correct flow during starting. Higher temperatures require
higher grade oils for satisfactory lubrication.
•
An oil pan and block coolant heater is required for
temperatures below -12 °C (10 °F).
•
For heavy duty driving or trailer towing, higher oil grades
15W-40 and 5W-40 oils are required, if temperatures are
over 10 °C (50 °F).
