AP-800D and BG-230D Asphalt Pavers Caterpillar

The proper lubricant viscosity grade is determined by the minimum outside temperature when the machine is started. The proper viscosity grade is also determined by the maximum outside temperature while the machine is operated. Use the column that is designated "Min" on the table to determine the viscosity grade that is required for starting a cold machine. Use the column that is designated "Max" on the table to determine the viscosity grade that is required for operating the machine at the highest anticipated temperature. When you refill the machine with lubricant, use the highest viscosity grade that is allowed for the ambient temperature when the machine is started. Machines that are continuously operated should use oils with higher viscosity in the final drives and in the differentials in order to maintain the highest possible oil film thickness. Consult your Caterpillar dealer if additional information is needed.

( 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 start occurs 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 Caterpillar 3500 Series and smaller Direct Injection (DI) diesel engines. API CF-4 oils are not recommended for Caterpillar machines with 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).
( 7 )	Commercial biodegradable hydraulic oil must meet the Caterpillar BF-1 specification. The listed ambient temperature range is for the current Cat BIO HYDO (HEES), not for commercial BF-1 oil.
( 8 )	Refer to the machine Operation and Maintenance Manual or contact your local Caterpillar dealer before using Cat BIO HYDO (HEES) or commercial BF-1 oil in Caterpillar Hydraulic Excavators.
( 9 )	Cat TDTO-TMS (Transmission Multi-Season) (synthetic blend that exceeds the TO-4M multigrade specification requirements).
( 10 )	Fully synthetic PAO (Polyalpaolefin) synthetic gear and bearing lubricant with no viscosity improvers. ISO Viscosity Grade 220 minimum viscosity index 150.
( 11 )	Fully synthetic PAO (Polyalpaolefin) synthetic gear and bearing lubricant with no viscosity improvers. ISO Viscosity Grade 100 minimum viscosity index 146.
( 12 )	SAE 85W-140 Gear Oil is the recommended lubricant for the AP-800D and the BG-230D paver conveyer planetaries.
