TRUEGARD R&O Industrial Oil 100 - 5 Gallon Pail

R&O stands for Rust and Oxidation inhibited, meaning this oil contains additives specifically for rust protection, oxidation resistance, and anti-foam control, but it does not include anti-wear (AW) additives. AW oils are formulated for higher-pressure systems where metal-to-metal contact requires additional wear protection, while R&O oils like this one are intended for low-pressure, light-duty hydraulic circuits where AW chemistry is not required.

This oil is designed for low-pressure, light-duty hydraulic equipment, with specific applications including forklifts, air tools, and light-duty presses. Always verify your equipment manufacturer's recommendation for the correct viscosity grade and oil type before use.

ISO VG 100 indicates a mid-to-higher viscosity hydraulic oil, thicker than commonly used grades like VG 46 or VG 68. A VG 100 grade is typically specified for equipment operating in warmer ambient temperatures or where the OEM calls for a heavier-bodied oil to maintain adequate film thickness; consult your equipment's manual to confirm the correct grade.

No - TRUEGARD R&O 100 is specifically designed for low-pressure, light-duty hydraulic systems. High-pressure hydraulic systems typically require an anti-wear (AW) formulation to protect against metal wear under elevated pressures; using an R&O oil in those systems may not provide sufficient protection.

This oil is formulated using only the highest quality virgin (base) oils, which provides a cleaner starting point compared to re-refined oils and contributes to the product's improved oxidation resistance, rust protection, and anti-foam performance over the service life of the fluid.

The product data does not address compatibility with other fluids, so mixing is not recommended without consulting TRUEGARD or your equipment manufacturer. As a best practice, drain and flush the system before switching to a new hydraulic oil to avoid potential additive incompatibility or performance degradation.
