The Author discusses, from his experience, various cases of bacterial infection of Diesel-engine lubricating oil, describes the damage done to engine components and the remedial action taken, and explains the general characteristics of aerobic and anaerobic infection of oil and water <piston and jacket cooling water is usually infected at the same time as, or before, the lube oil>. In the cases discussed, expert advice was sought from a leading authority on industrial microbiology and the oil companies concerned; a problem facing the ship's engineer is that expert advice is not always readily available, and it can be impracticable to send samples for analysis from a remote port. Bacterial infection of the lube oil appears to be occurring more frequently, and to be more serious, as fuel viscosities increase and cleanliness <e.g., of tank tops and bilges> becomes more difficult to maintain. The primary source of infection seems to be from bilges fouled with heavy oil and dirty harbour-water; a clean engine-room will prevent most if not all of these attacks. Ships' engineers of the Author's company have been given instructions on how to guard against lubricating-oil infection; these are summarised in the article.
