Lubricant / Capacity Notes

a.
Oil viscosity options:- 0W-20, 0W-30, 5W-20 & 5W-30 oils are special synthetic oils without VI improvers.
b.
Caterpillar list API CH-4 and API CI-4 as preferred oils and API CG-4 as an acceptable alternative. These oils must meet Caterpillar's ECF-1 specification to avoid reduced engine life. API CF-4 should not be used in Caterpillar diesel engines
c.
Hydraulic systems viscosity options: 0W-30 & 0W-20 oils are special synthetic oils without VI improvers
d.
23°F to 113°F
e.
Alternative recommendations, -4°F to 104°F: Refer to Technical; Power Transmission Fluid SAE 10W; Maxtron DEO SAE 10W-30 / Superlube TMS SAE 10W-30
f.
Alternative recommendations, 5°F to 122°F: Maxtron Power Transmission Fluid MV
g.
Alternative recommendations, 32°F to 122°F: Refer to Technical
h.
Viscosity options (Special synthetic oils without VI improvers): -40°C to 10°C, 0W-30; -5°C to 10°C, 5W-30; -25°C to 15°C, 10W; -20°C to 43°C, 30; -10°C to 50°C, 50
