Mobil™ DTE™ Oil Extra Heavy and Double Letter 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.
