Mobil DTE™ 20 Ultra Series oils are high performance anti-wear hydraulic oils with extended oil life capabilities and have demonstrated up to 2 times longer oil drain intervals versus similar competitive oils (*).

 

They meet the stringent requirements of hydraulic systems using high pressure, high output pumps as well as other hydraulic system components such as close clearance servo-valves and numerically controlled (NC) machine tools. The products exhibit outstanding oxidation and thermal stability allowing long oil life and minimized deposit formation in harsh conditions and with severe hydraulic systems using high pressure, high output pumps. The keep clean performance protects critical hydraulic system components from malfunction, such as tight tolerance servo and proportional valves found in many modern hydraulic systems.

 

These products met the most rigorous performance requirements of a wide range of hydraulic system and component manufacturers, allowing use of a single product with excellent performance characteristics.

 

(*) 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 type) requirements.

Features

Advantages and Potential Benefits

Outstanding Keep Clean Performance

Reduced system deposits and sludge to help 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, helps 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

 

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 when 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
