TRUEGARD Hydraulic Oil AW 46 55-Gallon Drum
TRUEGARD AW 46 is designed for general hydraulic systems requiring a stable VI and reliable oxidation resistance. This viscosity grade suits lighter duty to moderate systems, offering good thermal stability and high filterability to help maintain clean oil in filters and tanks. The formulation emphasizes resistance to sludge and varnish formation, supporting smoother long-term operation in equipment such as industrial presses, mobile cranes, and manufacturing line hydraulics.
TRUEGARD Hydraulic Oil AW 68, 55 Gallons
AW 68 provides higher film strength for heavier-duty hydraulic systems and equipment with higher operating temperatures. The oil is designed to offer robust antiwear properties and oxidation resistance, helping to protect pumps and components under load. This viscosity class is commonly used in systems with demanding seals and tighter tolerances, where higher viscosity helps maintain system pressure and protect metal surfaces during aggressive operation.
TRUEGARD Hydraulic Oil AW 32, 55 Gallon Drum
AW 32 is a lighter viscosity option suitable for systems with lower pressure, or where fast response and quick pumpability are prioritized. It emphasizes good thermal stability and antiwear properties, with resistance to oxidation similar to higher-viscosity grades. This oil can be advantageous in mobile equipment with rapid cycling and in applications where cold starts require better flow.
Ashless 46 AW Zinc-Free Hydraulic Oil (Sinopec) 55 Gallon
Though not in the final five, this zinc-free ashless option demonstrates a different additive approach, designed to meet stringent performance tests such as Denison HF-0 and ISO 11158. It targets high-pressure and double-pump configurations with reduced zinc content, aiding rust and wear protection while aligning with modern environmental considerations.
Shell Tellus S2 MX 46 Hydraulic Oil – 55 Gallon
Shell Tellus S2 MX 46 is designed for long fluid life and reliable wear protection in standard industrial hydraulics. Its formulation supports stability under turbine oil tests and broad temperature ranges, helping reduce varnish and sludge buildup while maintaining system cleanliness.
Presidential Hydraulic Oil 46
Presidential AW 46 leverages Group II base stock with anti-foam and rust protection features. This formulation aims to deliver good oxidation stability and broad temperature performance, suitable for a range of industrial and mobile hydraulic systems where dependable protection against wear and rust is important.
ULTRA 1PLUS AW ISO 32 Hydraulic Oil
ULTRA 1PLUS AW 32 is focused on isolating wear and rust while providing clean operation and extended filter life. It supports 5,000 hours of continuous operation in certain conditions and emphasizes anti-foaming and varnish resistance to help maintain pumpability and reliable performance across varying temperatures and loads.
Shell Tellus S2 MX 32 Hydraulic Oil – 55 Gallon
Tellus S2 MX 32 offers longevity and wear protection with emphasis on turbine stability tests and low-maintenance operation. It is positioned for systems requiring dependable pumpability at lower viscosity while maintaining resistance to oxidation and sludge formation.
Buying Guide: Key Purchase Considerations
- Viscosity class and system requirements: Lower-viscosity oils (like AW 32) flow quickly and are suitable for lighter loads or cold starts, while higher-viscosity oils (AW 46, AW 68) offer stronger film strength in high-load or high-temperature environments. Match viscosity to your equipment’s design and operating range.
- Oxidation and thermal stability: Oils with strong oxidation resistance help minimize sludge and varnish, supporting longer intervals between filter changes and cleaner hydraulic reservoirs.
- Antiwear and load protection: Antiwear additives protect pumps, valves, and actuators under heavy or prolonged loads. For equipment with high-pressure pumps or variable loads, prioritize oils with robust antiwear performance.
- Filterability and cleanliness: Oils that maintain good filterability reduce clogging and extend filter life, saving maintenance time and costs.
- Compatibility and certifications: Check OEM recommendations and certifications (e.g., DIN 51524, ISO 11158) to ensure compatibility with seals, metals, and pumps in your system.
- Environmental and regulatory considerations: Ashless or zinc-free formulations reduce environmental impact and may be preferred in certain systems, though some applications still require zinc-containing oils for anti-wrust protection.
- Availability and drum logistics: 55-gallon drums are standard for bulk industrial use. Consider availability, transport restrictions, and storage conditions to optimize logistics.
- Cost of ownership: While price matters, factor in filter changes, maintenance intervals, and potential downtime when evaluating total cost of ownership.
This selection provides a cross-section of commonly used 55-gallon hydraulic oils, spanning different viscosities, additive packages, and performance emphases. Buyers should align the chosen option with their equipment manufacturer recommendations, operating temperatures, duty cycles, and expected service intervals to achieve reliable hydraulic performance.
