Circulating Oils
Product Description
The Mobil DTE Double Letter Series of lubricants are high performance heavy duty circulating oils primarily intended for continuous
reuse in circulation lubrication systems for gears and bearings. They are formulated from high quality base stocks and a proprietary
additive system to provide superior protection against rust, excellent resistance to oxidation and thermal degradation, and a high level
of protection against wear, plus excellent resistance to high temperature corrosion of soft metals. They possess good demulsibility that
permits water and other contaminants to separate readily from the oil in the system reservoir. The Mobil DTE Double Letter Series are
available in four ISO viscosity grades from 150 to 460.
The Mobil DTE Double Letter Series family of products provides a versatile lubricant source for a wide range of industrial equipment.
They provide the users with very reliable and efficient operation in industrial circulating system applications, as well as other lubricant
application methods. They are particularly resistant to the effects of prolonged high temperature exposure and perform very well in
circulating systems with short oil residence times. Mobil DTE Double Letter Series oils have very good water seperability properties,
which allows water to separate readily in the system reservoir.
This combination of benefits has Mobil DTE Double Letter Series the product of choice for many users around the world, for the last
several decades.
Features & Benefits
The Mobil DTE family of products is well known and highly regarded world-wide based on their outstanding performance and the R&D
expertise and the global technical support which stand behind the brand. The highly versatile performance of one series of oils in this
family, Mobil DTE Double Letter Series oils, has made them the choice of many users around the world for many decades.
Mobil DTE Named oils enjoy an excellent reputation in the lubrication of the circulation systems of industrial gearboxes and paper
machines, plus a wide variety of ancillary equipment. As designs change and increase in severity, it is the challenge of our scientists to
understand the effect of these changes on the lubricant and to formulate these products for the broad versatility they are recognised for.
For the Mobil DTE Double Letter Series of lubricants this process has resulted in the use of a proprietary high quality base stocks for
outstanding oxidation stability, plus a unique additive combination to ensure the excellent, wide-ranging performance of these oils. A
review of the features, advantages and potential benefits of the product are shown below:

Features Advantages and Potential Benefits
Excellent thermal/oxidative and chemical degradation resistance Long lubricant charge life giving extended drain periods and
reduced product replacement costs
Reduced filter deposits and longer filter life
Protection against rust and corrosion in both the liquid and
vapour phase
Enhanced system cleanliness for reduced maintenance and unplanned
stoppages
Good demulsibility and avoids emulsion formation Improved operating efficiency and lower operating costs
Multiple application capability Reduced plant inventory savings
Applications
These oils are intended primarily for the lubrication of plain bearings, roller bearings, parallel shaft and bevel gearing. They are suitable
as multipurpose lubricants in systems not subject to shock loading and which do not require extreme pressure performance. They are
used in applications using splash, bath and ring oil arrangements and all other application methods involving pumps, valves and
auxiliary equipment. They are recommended for use in hydraulic systems where higher viscosity oils are specified.
· Moderate duty spur, bevel, helical and herringbone gear units
· The Mobil DTE Extra Heavy through HH oils are well suited for circulating systems
· The oils perform well at the elevated temperatures normally found in the dryer sections of paper machines
· Mobil DTE Extra Heavy and BB can also be used in hydraulic systems where clearances are relatively large and temperatures and
pressures are moderate
· Certain compressors and vacuum pumps handling air and inert gases provided the discharge temperatures do not exceed 150oC
