We accept
Castrol Hyspin AWH 68 is a high-performance anti-wear hydraulic oil engineered for demanding applications in industrial, mobile and off-highway hydraulic systems. With a viscosity grade of VG 68 (ISO 68), this fluid offers superior film strength, thermal and oxidation stability, and outstanding component protection under high load, high pressure, and wide temperature variations. Delivered in the 205-litre drum format, it is ideally suited for workshop, fleet, plant and mining operations where bulk fluid replacement and long service life are key.
The product is formulated with premium mineral base oils and a stabilised zinc-based additive anti-wear system. This combination provides robust protection against wear, corrosion, rust, foaming, entrained air and water contamination—ensuring hydraulic systems operate reliably and with reduced downtime. Hyspin AWH 68 is designed for applications that demand VG 68 anti-wear hydraulic fluid performance, including heavy-duty earthmoving, construction, mining, marine deck hydraulics, and large industrial hydraulic power units.
VG 68 Viscosity Grade for Heavy-Duty Systems
The ISO VG 68 rating ensures a thicker oil film and greater lubrication margin under heavy loads, high temperatures or large bore components. It is well-suited to hydraulic circuits with slower actuation, high pressure, and significant shear loads.
Superior Anti-Wear Protection
Featuring a zinc-based anti-wear additive package, Hyspin AWH 68 protects pumps, motors, valves and cylinders from metal-to-metal contact, even under demanding duty cycles. This reduces wear, increases component life and lowers maintenance costs.
Exceptional Thermal & Oxidative Stability
The formulation resists breakdown at elevated temperatures and extended operating periods. This means fewer sludge and deposit issues, longer oil life, and cleaner system internals—key for large hydraulic installations and mobile fleets.
Outstanding Water Separation & Demulsibility
Water intrusion via condensation, leaks or wash-down environments is a common hazard. Hyspin AWH 68 offers rapid water separation and maintains hydraulic performance under moisture exposure, preserving fluid integrity and preventing corrosion.
Excellent Rust & Corrosion Protection
Internal components such as steel, aluminum and yellow metals are protected from corrosion via dedicated inhibitors. This is vital for machines in humid, outdoor or marine environments where moisture and airborne salt may be present.
Low Foam Tendency & Reliable Operation
Foam formation and air entrainment can degrade hydraulic performance and cause cavitation. Hyspin AWH 68’s formulation includes foam control and air release additives, delivering consistent response and reliable actuation even under cyclic loads.
Wide Operating Temperature Range & High VI (Viscosity Index)
High viscosity index enables the oil to maintain more consistent viscosity across temperature changes, offering reliable performance in both cold start and hot running conditions. The VG 68 grade is particularly useful when ambient or equipment-temperature rises challenge lower grades.
Filterability & System Cleanliness
Designed to perform even with fine filtration systems, the oil promotes cleaner hydraulic system design and reduced filter change frequency, which in turn reduces total maintenance cost and improves uptime.
Castrol Hyspin AWH 68 is recommended for use in:
Heavy mobile hydraulic equipment such as excavators, wheel loaders, articulated haulers, graders and mining trucks.
Industrial hydraulic power units, presses, injection moulding machines, die-casting systems, and large hydraulic systems in manufacturing plants.
Marine deck hydraulics, offshore winches or crane systems where wide temperature range and load demand exist.
Construction and earthmoving machines operating under high pressure, high shear, and in dusty, humid or muddy environments.
Agricultural hydraulics with large bore cylinders, harvesters, balers, tractor hydraulic systems with implement lifts.
Centralised plant hydraulic systems, bulk fluid reservoirs, and large multi-pump installations where long service intervals and reliability are essential.
Do not use in systems that require fire-resistant fluids, food-grade specification oils, or zinc-free fluids unless approved by the equipment manufacturer.

Note: Typical values only. Actual production batches may vary within manufacturing tolerances.
Store the 205 L drum in a cool, dry, clean indoor or covered area. Avoid direct sunlight, excessive heat or freezing conditions.
Ensure the container remains sealed when not in use to avoid contamination from dust, water, or debris.
Use dedicated, clean dispensing equipment (pumps, hoses) to prevent cross-contamination with other oils or fluids.
Avoid mixing with incompatible fluids unless compatibility is confirmed by the manufacturer; mixing may degrade performance and void warranties.
Maintain correct labelling and fluid segregation to prevent accidental use in systems requiring different fluid types.
Dispose of used oil, filters and packaging in accordance with local environmental regulations and approved waste management procedures.
Refer to the Safety Data Sheet (SDS) for full health, safety and environmental information.
For optimal shelf life, store below 40 °C and above freezing; under proper storage the shelf life is approximately 5 years in original sealed container.
