Mobil DTE Named Series 

Mobil DTE™ Oil Named Series

Premium performance circulating lubricants

The Mobil DTE Oil Named Series of lubricants are formulated from highly refined base stocks and an additive system, which provide an extremely high level of chemical and thermal stability, rapid and complete separation from water and a high resistance to emulsification. They provide excellent protection against rust and corrosion, including resistance to salt water, and good antiwear properties. They have a high viscosity index which ensures minimum variation of film thickness with temperature and minimum power loss during the warm up period. These grades have excellent air release properties which allow entrained air to separate, thus avoiding pump cavitation and erratic operation.

Mobil DTE Oil Named Series has a reputation for long life, excellent equipment protection and outstanding versatility in a variety of applications. DTE Oil Named lubricants are used widely in steam turbines and hydroturbines with splash, bath and ring-oiling arrangements, and all other continuous circulation methods involving pumps, valves and ancillary equipment. They are recommended for the lubrication of plain and rolling bearings and parallel shaft gearing.
