equirements

The MTU conditions for preservative approval are speciﬁed in MTU Factory Standards for

Deliveries (MTL). The following standards are available:

• Initial-operation oil and corrosion-inhibitor oil, MTL 5051

• Corrosion inhibitors for external preservation, MTL 5052

The preservation product manufacturer is informed in writing if his product is approved by MTU.

Types of preservation

See "Preservation speciﬁcations", Chapter 9 (→ Page 83)

Initial operation oils and corrosion inhibiting oils for internal preservation

SAE 30 viscosity grade corrosion inhibiting oils are to be used for internal preservation (oil-

moistened components) of MTU engines and gearboxes.

These oils may also be used for running-in and acceptance testing procedures. Some are also suitable for

continuous operation, see "Approved ﬂuids and lubricants", Chapter 8 (→ Page 45).

Corrosion inhibitors for external preservation

For external preservation, all non-painted parts are to be treated with a corrosion inhibitor providing

a wax-like protective coating after the inhibitor solvent has evaporated.

Corrosion inhibiting oils for internal preservation of the fuel system

Fuel injection-pump test oil conforming to DIN ISO 4113 is to be used for internal preservation of the fuel

system. T he engine should be run with these oils for the last 10 minutes before shutdown.

Preservation can also be effected using diesel fuel to which approximately 10-12% corrosion-

inhibitor oil for internal preservation has been added.
