Mobil DTE 10 Excel™ Series

Product Description

Mobil DTE 10 Excel™ Series are high performance anti-wear hydraulic oils specifically designed to meet the needs of modern, high pressure, industrial and mobile equipment hydraulic systems.

The Mobil DTE 10 Excel Series is constructed from selected base oils and a proprietary additive system to provide well balanced performance in a range of applications.  The products exhibit exceptional oxidation and thermal stability allowing long oil life and minimized deposit formation in severe hydraulic systems using high pressure, high output pumps.  The innovative ultra keep clean performance protects critical hydraulic system components from malfunction, such as tight tolerance servo and proportional valves found in many modern hydraulic systems.  The shear stable, high viscosity index allows for a wide operating temperature range maintaining maximum hydraulic efficiency and component protection at both low and high temperatures.  Outstanding air release properties provide an added measure of protection in systems with low residence time helping to prevent cavitation damage and micro dieseling.  The carefully selected base oil and additives allow passing results of acute aquatic toxicity testing (LC-50, OECD 203) and the zinc free anti-wear system provides a high degree of protection in gear, vane and piston pumps while also minimizing deposit formation.

Formulated with extensive laboratory and in-service field testing, the Mobil DTE 10 Excel series can help provide quantifiable increases in hydraulic efficiency compared to other ExxonMobil’s hydraulic oils.  This can translate to reduced power consumption or increased machine output, resulting in monetary savings. 

In controlled laboratory efficiency testing, Mobil DTE 10 Excel was measured to provide up to a six percent improvement in hydraulic pump efficiency compared to Mobil DTE 20 when operating in standard hydraulic applications.

In additional laboratory and in-service field demonstrations conducted on a wide range of modern hydraulic systems, the Mobil DTE 10 Excel series demonstrated, compared to ExxonMobil’s conventional hydraulic fluids, exceptional oil life, outlasting these fluids by up to three times, while maintaining outstanding hydraulic system cleanliness and component protection.  Mobil DTE 10 Excel also demonstrated the value of its high viscosity index and outstanding shear stability by operating successfully in temperatures as low as -34°C and by maintaining ISO viscosity grade.

Mobil DTE 10 Excel has also been tested in standard vane pumps under controlled conditions directly against competitive products.  At the end of the 30 minute test, Mobil DTE 10 Excel resulted in less system heat generation and the system temperatures were measured to be 6°C-7°C less than certain competitive products run under identical conditions.


Features and Benefits

Energy Efficiency

The energy efficiency of Mobil DTE 10 Excel relates solely to the fluid performance when compared to ExxonMobil's standard hydraulic fluids. The technology used allows up to 6% increase in hydraulic pump efficiency compared to Mobil DTE 20 series when tested in standard hydraulic applications under controlled conditions. The energy efficiency claim for this product is based on test results on the use of the fluid conducted in accordance with all applicable industry standards and protocols.

The Mobil DTE 10 Excel Series hydraulic oils provide outstanding hydraulic system efficiency; ultra keep clean performance, and a high degree of fluid durability. The hydraulic efficiency feature can lead to reduced energy consumption for both industrial and mobile equipment, reducing operating costs and improving productivity. Their excellent oxidation and thermal stability allows extension of oil and filter change intervals while helping to ensure clean systems. Their high level of anti-wear properties and excellent film strength characteristics result in a high degree of equipment protection that not only results in fewer breakdowns but helps improve production capacity.
