The maintenance and operation of lubricating oil systems in marine diesel engines are discussed. Clarification of oil by running it periodically of continuously through a centrifuge is recommended. Centrifuges of automobile type can also be used for clarifying oil on river motor-ships. In addition, lubricating oils must periodically be tested for contents of fuel residue and water. For this purpose the motor-ships must be equipped with laboratories. In general, a 4-pct content of fuel oil in lubricating oils can be admitted. This content can be tested by measuring viscosity. For instance, at 4-pct fuel content the viscosity of M12V lubricating oil is lowered to 9.5 centistokes at 100C. The flash point of this lubricating oil with a 4-pct fuel content is about 200C. The presence of water in lubricating oil is briefly discussed. In railway practice only traces of water 0.05 are permitted. According to LIVT a water content of 0.4 pct can be admitted in oils used for marine power plants. The lubricating oil can be tested for water by using magnesium sulphate.
