Truegard AW 68 Hydraulic Oil, Zinc-Free, SYN 55 Gallon Drum is a high-performance synthetic hydraulic fluid engineered for advanced industrial applications. Formulated with a precise viscosity grade of 68, this anti-wear (AW) oil delivers exceptional protection against wear and tear in high-pressure hydraulic systems. Its zinc-free (ashless) additive package makes it ideal for use in environmentally sensitive areas and equipment requiring specialized certifications, helping reduce the risk of metal corrosion and meeting stringent environmental regulations. As a synthetic (SYN) lubricant, it ensures superior stability and performance across a wide temperature range compared to conventional mineral oils, while the 55-gallon drum packaging supports efficient bulk usage for large-scale operations.

Frequently asked questions

Find answers to common questions about our products and services

  • AW 68 refers to an ISO viscosity grade of 68, making it a relatively heavier hydraulic fluid compared to lighter grades such as AW 32 or AW 46. It is best suited for high-pressure industrial hydraulic systems that operate at higher temperatures or require a thicker oil film to maintain adequate wear protection and component longevity.

  • Conventional zinc-based hydraulic oils use zinc dialkyldithiophosphate (ZDDP) as an anti-wear additive, which can cause corrosion on certain metal alloys and may be restricted by some equipment OEM specifications or environmental regulations. This zinc-free, ashless formulation eliminates that risk, making it the appropriate choice for environmentally sensitive areas and equipment that prohibits zinc-containing fluids.

  • The synthetic base oil delivers superior thermal and oxidative stability, allowing it to maintain consistent viscosity and protective performance across a wider temperature range than conventional mineral oils. This is especially valuable in high-pressure hydraulic systems subject to fluctuating or extreme operating temperatures.

  • The higher the ISO viscosity grade number, the thicker the oil at operating temperature - AW 68 is heavier than AW 46 and is typically specified for systems running at higher temperatures or requiring greater oil film thickness for load protection. Always reference your equipment's OEM hydraulic fluid specification to confirm the correct viscosity grade before filling or changing fluids.

  • This oil is engineered for advanced industrial applications involving high-pressure hydraulic systems. Its zinc-free, ashless formulation and compliance with stringent environmental regulations make it particularly well-suited for operations in environmentally sensitive facilities or any application where equipment certifications restrict the use of zinc-based additives.

  • The product data does not specify compatibility with mineral-based hydraulic fluids, and mixing synthetic and mineral oils can dilute the performance benefits of the synthetic formulation. It is generally best practice to flush the system before switching fluid types; consult your equipment manufacturer's guidelines and the product's Safety Data Sheet for specific changeover procedures.
