( 1 ) 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, which allows the oil to become more viscous due to cooler ambient temperatures.
( 2 ) API CF oils are not recommended for AVSpare 3500 Series and smaller Direct Injection (DI) diesel engines. API CF-4 oils are not recommended for AVSpare 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 AVSpare'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 requirement's of AVSpare's ECF-1 specification may cause reduced engine life.
( 5 ) API CG-4 oils are acceptable for all AVSpare diesel engines. When API CG-4 oils are used, the oil drain interval should not exceed 250 hours.
( 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).
( 7 ) Commercial biodegradable hydraulic oil (HEES) must meet the AVSpare BF-1 specification. The listed ambient temperature range is for the current Cat BIO HYDO (HEES), not for commercial BF-1 oil.
( 8 ) Contact your local AVSpare dealer before using Cat BIO HYDO (HEES) or commercial BF-1 oil. Your machine may not be compatible with biodegradable hydraulic oil.
( 9 ) Cat TDTO-TMS (Transmission Multi-Season) (synthetic blend that exceeds the TO-4M multigrade specification requirements).
( 10 ) First Choice: Cat Arctic TDTO SYN - SAE 0W-20. Second Choice: Oils of full synthetic base stock without viscosity index improvers that meet the performance requirements of the TO-4 specification for the SAE 30 viscosity grade. Typical lubricant viscosity grades are SAE 0W-20, SAE 0W-30, and SAE 5W-30. Third Choice: Oils that contain a TO-4 additive package and a lubricant viscosity grade of SAE 0W-20, SAE 0W-30, or SAE 5W-30.
( 11 ) First Choice: Oils of full synthetic base stock without viscosity index improvers that meet the performance requirements of the TO-4 specification for the SAE 30 viscosity grade. Typical viscosity grades are SAE 0W-20, SAE 0W-30, and SAE 5W-30. Second Choice: Oils with a TO-4 type additive package and a lubricant viscosity grade of SAE 0W-20, SAE 0W-30, or SAE 5W-30.
( 12 ) With exception to the hydraulic drive winch gear case,use SAE 30 viscosity grade for 0°C (32°F) to 43°C (110°F) or Cat TDTO-TMS for -20°C (-4°F) to 50°C (122°F).
( 13 ) Do not use SAE 50 viscosity grade oil in ICM controlled transmissions. Do not use SAE 50 viscosity grade oil for the hydraulic drive winch case.
