Manufacturer's description

Mobil DTE 20 Ultra Series oils are high-performance, anti-wear hydraulic oils with extended oil-life capabilities, demonstrated to deliver up to twice the oil-drain intervals versus similar competitive oils (with a viscosity index around 100 and a zinc-based anti-wear system meeting at least ISO 11158 L-HM and/or DIN 51524-2 HLP requirements). They meet the stringent demands of hydraulic systems using high-pressure, high-output pumps, close-clearance servo-valves and numerically controlled (NC) machine tools, exhibiting outstanding oxidation and thermal stability that supports long oil life and minimized deposit formation under harsh conditions. Mobil DTE 27 Ultra is the ISO VG 100 grade of the series, with a kinematic viscosity of 100.2 mm²/s at 40 °C and 11.9 mm²/s at 100 °C, a viscosity index of 108, a pour point of -33 °C and a flash point of 278 °C. Its FZG scuffing fail load stage is 12 (ISO 14635-1). The series offers outstanding keep-clean performance that protects tight-tolerance servo and proportional valves, enhanced anti-wear performance meeting major pump manufacturer requirements, enhanced corrosion protection across a wide variety of component metallurgy, and controlled demulsibility that protects systems from small and large quantities of water while extending filter life. These products are recommended for hydraulic systems prone to deposit build-up, systems requiring high load-carrying capability, systems where trace water is unavoidable, and systems containing gears and bearings. Mobil DTE 27 Ultra carries the HOCNF Norway-NEMS (Black) approval and meets DIN 51524-2:2017-06, ISO 11158 L-HM, ASTM D6158 (Class HMHP) and China GB 11118.1-2011 L-HM (General and HP) requirements.

Applications

• Hydraulic systems critical to deposit build-up, or where sludge and deposits form with conventional products.
• Hydraulic systems requiring a high load-carrying capability and anti-wear protection, and where thin oil-film corrosion protection is an asset.
• Where small amounts of water are unavoidable.
• Systems containing gears and bearings.
• Machines employing a wide range of components using various metallurgy.

Performance & benefits

• Outstanding keep-clean performance — reduced system deposits and sludge, helping protect equipment and extend equipment life, reduce maintenance costs and improve total system performance.
• Enhanced anti-wear performance — meets or exceeds major pump manufacturer requirements, helping extend component life.
• Exceptional thermal and oxidation stability — helps reduce maintenance downtime and costs by contributing to system cleanliness and deposit reduction, even under harsh operating conditions and high power density.
• Enhanced corrosion protection — helps ensure protection with a wide variety of component metallurgy.
• Controlled demulsibility — protects systems from small and large quantities of water and helps extend filter life.
• Quality reserve — maintains performance features even under severe service conditions and extended drain intervals.
