Frequently asked questions

Find answers to common questions about our products and services
  • AW stands for Anti-Wear, and 46 refers to the ISO viscosity grade of approximately 46 centistokes at 40°C, making this a medium-weight hydraulic fluid. It is one of the most widely specified grades for general industrial and mobile hydraulic systems; always verify your equipment manufacturer's recommendation to confirm that ISO VG 46 is the correct grade before filling.

  • Zinc-based anti-wear additives can react adversely with yellow metals such as copper, brass, and bronze commonly found in hydraulic pumps, valves, and fittings, potentially causing corrosion or deposit buildup. A zinc-free formulation is especially important for systems containing these metals and is also preferred in applications where environmental regulations or OEM specifications prohibit zinc-containing chemistries.

  • Mixing hydraulic fluids with different additive packages - particularly switching from a zinc-containing fluid to this zinc-free formula - is generally not recommended, as incompatible additives can interact and compromise performance. Draining and flushing the system before filling with Truegard AW 46 is the safest approach to ensure the additive chemistry performs as intended.

  • Truegard AW 46 is designed for a wide variety of industrial and mobile hydraulic applications, including machine tools, hydraulic presses, construction and agricultural equipment, and forklifts - essentially any system where a zinc-free, anti-wear ISO VG 46 hydraulic fluid is specified by the equipment manufacturer.

  • Strong water separation prevents moisture from emulsifying into the oil, which would degrade lubrication quality and promote internal corrosion. Effective air release minimizes entrained air bubbles that can trigger cavitation - a condition that physically damages pumps, seals, and valves while reducing overall system efficiency and responsiveness.

  • No - this product uses advanced additive technology specifically formulated to deliver robust anti-wear and oxidation protection without relying on zinc compounds. The result is strong wear defense comparable to conventional AW-grade oils, while eliminating the compatibility concerns associated with zinc chemistry in sensitive system components.
