Verification test of the semi-permanent use of engines and no waste oil was conducted over a period of 8 years 33,000h, the results of which were presented in SAE 2011-01-2113 at SAE 2011 held at Kyoto, Japan. The test has reached 10 years 45,000h as of August 2013 and is still on-going. This technology which almost completely removes sludge and maintains lubricating oil cleanliness has been in practical use in many marine and power diesel engines for a long time. It is theoretically and technologically simple to integrate various oils only if the oil is clean without sludge. Clean lubricating oil even with a low alkalinity value can prevent engine corrosion due to acids. In this paper, EBAS (Efficient BASicity) is used instead of TBN as proposed by C. Amblard and S. Esson at CIMAC 2013 held at Shanghai, China.
