Product Description

Castrol HYSPIN HVI 15 is a high-viscosity-index, zinc-free anti-wear hydraulic oil designed for hydraulic systems requiring ISO VG 15 fluid with excellent temperature-viscosity performance. Key applications include mobile hydraulic equipment, precision hydraulic systems, industrial machinery, machine tools, and hydraulic circuits exposed to wide temperature variations or cold-start conditions. It is formulated from high-quality mineral base oils with a zinc-free/ashless additive system to provide anti-wear protection, oxidation resistance, corrosion protection and good foam control. Castrol's Australian catalogue confirms HYSPIN HVI 15 as part of its HVI hydraulic-oil range, with a 205 L pack available under item code 3413654.

The HYSPIN HVI range is designed for applications where maintaining suitable viscosity over a broad temperature range is important. The high viscosity index helps reduce viscosity changes as operating temperature changes, while the anti-wear formulation protects hydraulic pumps and components under demanding operating conditions.

Product Type

• High-Viscosity-Index Hydraulic Oil
• Zinc-Free / Ashless Anti-Wear Hydraulic Fluid
• ISO VG 15
• Mineral-Based Hydraulic Oil
• Industrial Hydraulic Fluid
• Mobile Hydraulic Lubricant
• HVLP-Type Hydraulic Fluid

Specifications & Performance

Castrol's product information identifies the HYSPIN HVI family with the following performance classifications/requirements:

• DIN 51502 – HVLP
• ISO 6743/4 – Hydraulic Oils Type HV
• DIN 51524 Part 3
• Parker Hannifin (Denison) HF-0, HF-1 & HF-2
• Cincinnati Lamb (Milacron) P-68, P-69, P-70
• Eaton E-FDGN-TB002-E
• US Steel 126 & 127

These are particularly relevant for hydraulic systems requiring high-VI hydraulic-fluid performance.

Key Benefits

High Viscosity Index

• Maintains more consistent viscosity across changing temperatures
• Provides improved cold-start performance
• Helps maintain hydraulic response as operating temperature increases
• Suitable for equipment exposed to significant ambient-temperature variations

Zinc-Free Anti-Wear Technology

HYSPIN HVI uses a zinc-free/ashless additive system, making it suitable where zinc-free hydraulic technology is required or preferred. Independent Castrol distributor information also identifies the HVI range as high-purity mineral-oil-based, high-VI, zinc-free anti-wear hydraulic oil.

Hydraulic Component Protection

• Helps reduce pump and component wear
• Provides protection under high-pressure operation
• Helps protect against corrosion and rust
• Supports reliable hydraulic-system operation

Oxidation & Foam Control

The formulation is designed to provide:

• Good oxidation resistance
• Corrosion protection
• Controlled foaming
• Reliable lubricant performance during continuous operation

Applications

Castrol HYSPIN HVI 15 can be considered for:

• Hydraulic control systems
• Precision hydraulic equipment
• Industrial machinery
• Machine tools
• Mobile hydraulic equipment
• Hydraulic systems operating in cold environments
• Equipment experiencing wide temperature variations
• Hydraulic systems requiring ISO VG 15 high-VI fluid

Because ISO VG 15 is a very low hydraulic-oil viscosity grade, the equipment manufacturer's viscosity requirement should always be confirmed before selecting this product.

Typical Properties

For the exact Australian product, I would not publish estimated numerical values for density, viscosity at 40°C, viscosity index, pour point or flash point unless they are confirmed from the current product-specific Castrol PDS.

The currently available Castrol Australian catalogue confirms:

The current Castrol Australia catalogue lists HYSPIN HVI 15 as a 205 L product with item code 3413654 and barcode 9310084028984.

Important Product Note

HYSPIN HVI 15 should not be confused with HYSPIN AWH 15 or HYSPIN AWH-M 15.

These are different Castrol hydraulic-oil families:

Castrol's historical Australia/New Zealand product listings separately identify all three product families.

Storage

Store in the original sealed container in a clean, dry location away from excessive heat, moisture and direct sunlight.

Keep containers tightly closed when not in use. Avoid contamination with water, dirt, dust, fuel or other lubricants.

Health & Safety

Avoid prolonged or repeated skin contact. Wear appropriate protective gloves when handling the product.

High-pressure hydraulic-fluid injection can cause serious injury even when the external wound appears minor. Hydraulic systems should always be depressurised before maintenance.

The current Castrol SDS identifies HYSPIN HVI 15 as a hydraulic fluid and highlights the importance of precautions for high-pressure applications.
