Frequently asked questions

Find answers to common questions about our products and services

  • AW 68 refers to ISO VG 68, meaning the oil has a nominal kinematic viscosity of 68 cSt at 40°C - a relatively heavy grade suited for high-pressure or higher-temperature hydraulic systems where a thicker oil film is needed. Always consult your equipment manufacturer's hydraulic fluid specifications to confirm ISO VG 68 is the recommended viscosity before using this product.

  • Zinc-based anti-wear additives (commonly ZDDP) can corrode yellow metals such as copper, brass, and bronze found in many pumps, valves, and hydraulic fittings. A zinc-free formula delivers anti-wear protection through alternative additive chemistry, making it a safer choice for systems with yellow-metal components or in applications where zinc-free fluids are specifically required by the OEM.

  • Yes - the product is formulated to support a wide variety of industrial and mobile hydraulic applications. It is based on high-quality mineral base stocks, so it is intended for use in conventional petroleum-compatible hydraulic systems across both stationary industrial machinery and mobile equipment.

  • Mixing different hydraulic fluids is generally not recommended, as it can compromise additive packages and system performance. When switching to Truegard AW 68, it is best practice to flush the hydraulic system before filling with the new fluid to avoid compatibility issues.

  • Good water separability means the oil quickly sheds any moisture that enters the system, preventing emulsification that can degrade lubrication and damage components. Fast air release reduces the likelihood of cavitation - where collapsing air bubbles erode pump parts - helping maintain consistent system efficiency and reducing maintenance needs.

  • Superior thermal stability means the oil resists oxidation and viscosity breakdown when exposed to sustained heat and demanding operating cycles, so it maintains consistent protective film strength over time. This translates to fewer fluid changes, reduced sludge and varnish buildup, and longer service life for both the oil and the hydraulic components it protects.
