Supplemental heat is recommended for cold-soaked starts below the minimum ambient temperature. Supplemental heat may
be required for cold-soaked starts that are above the minimum temperature that is stated, depending on the parasitic load and
other factors. Cold-soaked starts occur when the engine has not been operated for a period of time, allowing the oil to become
more viscous due to cooler ambient temperatures.
( 2 )
API CF oils are not recommended for Caterpillar 3500 Series and smaller Direct Injection (DI) diesel engines. API CF-4 oils are
not recommended for Caterpillar machine diesel engines.
( 3 )
Cat Arctic DEO SYN is an SAE 0W-30 viscosity grade oil.
( 4 )
API CI-4, API CI-4 PLUS, and API CH-4 oils are acceptable if the requirements of Caterpillar's ECF-1 (Engine Crankcase Fluid
specification - 1) are met. API CI-4, API CI-4 PLUS, and API CH-4 oils that have not met the requirements of Caterpillar's ECF-
1 specification may cause reduced engine life.
( 5 )
API CG-4 oils are acceptable for use in all Caterpillar machine diesel engines. When API CG-4 oils are used, the oil change
interval should not exceed 250 hours. API CG-4 oils that also meet API CI-4, API CI-4 PLUS, or API CH-4 must also meet the
requirements of the Caterpillar ECF-1 specification.
( 6 )
SAE 10W-30 is the preferred viscosity grade for the 3116, 3126, C7, C-9 and the C9 diesel engines when the ambient
temperature is between -18° C (0° F) and 40° C (104° F).
