The Mobil DTE family of products is well known and highly regarded worldwide based on their outstanding performance and the RandD expertise and the global technical support which stand behind the brand. The highly versatile performance of Mobil DTE Oil Named oils has made them the oil of choice for a multitude of industrial equipment applications around the world.

Specific grades of Mobil DTE Named oils enjoy an excellent reputation in the lubrication of the circulation systems of steam turbines and hydro turbines, including geared turbines, plus a wide variety of ancillary equipment. As designs change and increase in severity, it is the challenge of our formulation 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 Oil Named Series of lubricants, this process has resulted in the use of special 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
Very high level of chemical and thermal stability and resistance to sludging and varnishing	Long oil charge life in circulation systems and reduced oil replacement costs
	Less unplanned downtime and reduced maintenance costs
Excellent water release properties	Improved operating efficiency
Very good antiwear protection	Longer equipment life, reduced maintenance and downtime
Long term protection against rust and corrosion	Longer equipment life, reduced maintenance and downtime
High resistance to foaming and excellent air release	Avoids pump cavitation, noisy and erratic operation
Highly versatile - multiple applications	Rationalize inventory, reduced inventory costs

Applications
