6.2 Lubricant Recommendation
It is important to comply with the oil drain and filter change intervals to guarantee the proper
operation of your S. I. Moteurs Baudouin equipment.
Baudouin recommends that the oils that are formulated specifically for heavy duty gas engines
should be used. The oils for gasoline or diesel engines cannot be used.
Baudouin recommends that the oils that formulated with Group II base stock should be used.
Baudouin recommends the use of oils that have the sulfated ashes lower than 0.6%. That can
produce less deposits on the valves and pistons and extend the service life of the engine.
For the engines of new installation or the use of new types of oils, Baudouin recommends take
oil samples frequently from the engines for analysis to make sure the engine can be protected
completely, and make records of the analysis results to evaluate the quality of the oils and
determine the oil changes.

Viscosity
As the viscosity of lubricating oil is
dependent on temperature, the choice
of SAE grade should be governed by
the ambient temperature prevailing at
the engine operating site. Should the
temperature fall temporarily below the
limits of the SAE grade selected, cold
star-ting may be affected but the engine
will not be damaged. In order to keep
wear to a minimum, do not exceed
application limits for extended periods
of time. Synthetic lubricating oil features
an improved temperature and oxidation
stability.
