Mobil DTE™ 20 Ultra Series

Hydraulic Oil

A breakthrough in hydraulic oil technology that delivers outstanding productivity for your machines.

Approved by industry leaders, Mobil DTE™ 20 Ultra Series offers improved, well-balanced performance to meet the demands of high-pressure and high-output hydraulic systems, delivering increased oil life, better wear protection and better deposit control in the process.

Mobil DTE 20 Ultra series hydraulic oils offer:

2X longer oil drain intervals*
Extended component life
Extended filter life

*Mobil DTE 20 Ultra Series oils have demonstrated up to 2 times longer oil drain intervals versus similar competitive oils (ISO VG 46 with a viscosity index around 100 and a zinc-based anti-wear system - meeting at least ISO 11158 (L-HM) and/or DIN 51542-2 (HLP type) requirements) in demanding Mobil Hydraulic Fluid Durability (MHFD) testing.

Product Description

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 reduced deposit formation in harsh conditions and with severe hydraulic systems using high pressure, high output pumps. The keep clean performance helps 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 and Benefits

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 conditions
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.
