Valvoline Hydraulic System Fluid

Valvoline Hydraulic System Fluid: Precision Protection for Every Application

Valvoline has been engineering lubricants since 1866, and that century-and-a-half of formulation expertise carries directly into their hydraulic system fluid lineup. Whether you're maintaining a farm tractor, a piece of heavy construction equipment, or an industrial machine, Valvoline brings the same science-backed chemistry to hydraulic applications that has made it one of the most trusted names in lubrication.

The Valvoline Hydraulic Fluid Lineup

Valvoline's hydraulic fluid range covers two distinct but complementary product lines, each engineered for a specific set of demands:

• Valvoline AW Hydraulic Oil (ISO 32 / 46) – Formulated with premium high viscosity index (VI) base oils and additives, these zinc-based, non-detergent oils deliver excellent oxidation resistance and demulsibility characteristics, along with built-in rust and foam inhibitors. The outstanding demulsibility and high VI make AW Hydraulic Oils particularly well-suited for mobile equipment applications, as well as machine tools, servo controls, metalworking equipment, circulating systems, and gear cases.
• Valvoline Unitrac Hydraulic Fluid – A high-performance, multi-purpose all-weather fluid designed for agricultural tractors and off-highway equipment. Unitrac is uniquely formulated to provide excellent antiwear, oxidation, ferrous rust, copper corrosion, sludge, and varnish protection. It also reduces wet brake and Power Take-Off (PTO) chatter — a common pain point with farm and utility equipment. Unitrac is recommended for hydraulic systems, final drives, transmissions, differentials, wet brake systems, PTOs, and hydrostatic drives, with compatibility across major brands including John Deere, New Holland, Massey Ferguson, Case, and Kubota.

Why Valvoline Stands Out in Hydraulic Fluids

What sets Valvoline apart in the hydraulic system fluid category is the depth of engineering behind each formula. Valvoline's hydraulic fluids meet and exceed a broad set of industry and OEM specifications, including Eaton, Dennison HF-0/HF-1/HF-2, DIN 51524.2, JCMAS, and US Steel standards — giving operators confidence that the fluid will perform within the tolerances their equipment demands. The anti-foam chemistry in both product lines is engineered to minimize cavitation, a leading cause of hydraulic pump wear and system inefficiency.

Across both agricultural and industrial settings, Valvoline hydraulic fluids are built to resist thermal breakdown, prevent varnish and sludge accumulation, and keep system components operating cleanly over extended service intervals. For anyone managing heavy equipment or farm machinery, that translates directly to lower maintenance costs and longer component life.
