What Kind of Hydraulic Fluid Does a Caterpillar Cat 336 Excavator Prefix-YBN Take?
The Caterpillar Cat 336 Excavator (Prefix-YBN) requires Cat HYDO Advanced 10W hydraulic oil, the primary fluid recommended by Caterpillar. This premium oil enhances hydraulic efficiency, protects internal components, and provides excellent performance in high-pressure systems like the Cat 336 boom, stick, and bucket circuits.
For extreme temperatures, operators may use approved Cat Bio HYDO Advanced or Cat DEO-ULS alternatives, depending on environmental requirements and operating conditions. Always confirm compatibility with the machine’s service manual or your local Caterpillar dealer before switching fluids.
Using the correct hydraulic fluid is critical to prevent wear, overheating, cavitation, and system contamination—ensuring smooth, consistent performance from your Cat 336’s hydraulic system during heavy-duty operations.
