Restrictions on Series 2000 M84, 2000 M94, and 4000-03 marine applications

The engines of the Series 2000 M84, 2000 M94 and 4000-03 marine must not use Category

1oils.

Restrictions on Series 595, 956 TB31/TB32/TB33 and 1163 applications

For f ast commercial ferries with Series 595, Series 956 TB31/TB32/TB33 or 1163 engines,

Category 2 or 3 oils are generally speciﬁed.

Restrictions on Series 8000 applications

Only the following engine oils may be used:

• BP Energol HPDX SAE 30 / SAE 40

• Castrol HLX SAE 30 / SAE 40

• Chevron Delo 400 SAE 30 / S AE 40

• Exxon Mobil Delvac 1630 SAE 30

• Exxon Mobil Delvac 1640 SAE 40

• Shell Sirius X SAE 30 / SAE 40

• MTU Power Guard DEO SAE 40

SAE-40 engine oils may only be used in combination with preheating and oil priming (T

oil

>30 °C

Restrictions when using low SAPS oils

Oil Categories 2.1 and 3.1 may be used if the sulfur content in the fuel does not exceed

500 mg/kg.

Engine oil requirements for gas engines

Viscosity grade SAE 40 is stipulated for gas engines!

The selection of a suitable engine oil for gas engines depends primarily on the type of gas used to power the engine.

Another signiﬁcant factor is the quality of the gas r

egarding its purity. This requires that the operator regularly carries

out gas checks. The gas-engine oils to be used feature a low ash content (< 0.6%) and base numbers within a range

of 4-6 mgKOH/g. This prevents increased ash depo

sits which can lead to reduced catalytic converter performance.
