RAYCO LUBRICATION & FLUID SPECIFICATIONS
Engine Oil
During the initial break-in period, the engine will consume more oil than usual.
Check the engine oil level daily.
See the Engine Operator Manual for engine oil specifications.
Engine Fuel
See the Engine Operator Manual for engine fuel specifications.
USE GASOLINE ONLY.
Hydraulic Oil (Petroleum-Mineral Base)
Your Rayco machine is filled at the factory with Conoco Powerflow AW HVI 32 Hydraulic Fluid. This oil is formulated to
provide the proper operating characteristics in a wide range of climates. When refilling, always use Conoco Powerflow AW
HVI 32 or one of the recommended brands below. Failure to use the proper hydraulic oil can lower performance and shorten
the life of critical components. Do NOT mix different types of hydraulic fluids!
Rayco’s oil specifications address the following concerns:
• High-temperature viscosity
• Low-temperature flow properties
• Viscosity lifespan
• High-pressure wear characteristics
• Filterability
• Multi-metal compatibility in the presence of water
Rayco recommends the following hydraulic oils for your Rayco machine:
Conoco-Phillips MegaFlow AW HVI 32……….…Viscosity 6.0 cSt @ 100°C / 32 cSt @ 40°C / Pour -51°C (-60°F)
Shell Tellus T 32 ………………………………….Viscosity 6.1 cSt @ 100°C / 32 cSt @ 40°C / Pour -39°C (-38°F)
Mobil DTE 13M……………………………………..Viscosity 6.5 cSt @ 100°C / 33 cSt @ 40°C / Pour -46°C (-51°F)
If choosing an oil other than those recommended above, the following specifications should be used:
• Kinematic Viscosity: 6-7 cSt @ 100°C / 32-33 cSt @ 40°C
• Pour point: -35° F (-37° C) or colder
• Viscosity stabilizers, excellent resistance to viscosity breakdown (shear).
• Anti-wear, Anti-foam formulation, for use in all pump types at all pressures.
• Low-zinc additives; zinc levels should not exceed .08% of total weight
Clean hydraulic oil is critical to achieve high performance and get long life from your hydraulic system. The oil and filter
should be changed in accordance with the instructions contained in the “Maintenance Intervals” section of your manual.
The hydraulic oil should be changed immediately if it appears dirty or smells burnt.
Biodegradable Hydraulic Oil
Panolin HLP Synthetic Ester Base VG32 is the only approved Bio-Degradable Hydraulic oil for Rayco machines. All mineral
base oils must be completely drained out of system and components before refilling with Panolin HLP Synthetic VG32
Bio-degradable oil.
Final Drive Gear Oil
