In the first part of this series, we covered the reasons why lubrication is necessary for antifriction bearings and the duties that the lubricant has to perform. We will now consider the lubricant itself.

It is very rarely that we have published any article which casts any reflection on the advantages of using fully detergent oils. We believe that the advantages are many and that these oils should be used to an even greater extent than they are. In the U.S.A. many motor car manufacturers recommend them for normal use. In this article, which is an abstract of a paper written by one of the Ford Motor Company U.S.A. staff, the results of tests on private motor car engines showed increased bearing wear when Heavy Duty oils were used, and especially when used with leaded petrol. Cylinder bore wear was considerably reduced. In spite of this report, as mentioned in our May 1952 issue, according to the ChekChart, Fords recommended, in the U.S.A., Heavy Duty oils for their cars if subjected to abnormally hard driving conditions. It would seem, therefore, that further confirmatory or probably otherwise tests are needed.

Stewarts and Lloyds by Messrs. Ransomes & Rapier Ltd., Ipswich. It was constructed in their works and erected on site at Northamptonshire, where it is engaged on stripping iron ore.

The lubricating properties of molybdenumdisulphide powder have been referred to in these columns before see issue for April, 1950, p. 1C, and April, 1951, p. 14 and these powders have been available in lubricating form for some years in the U.S.A. under the trade name of Molykote Lubricants, made and marketed by The Alpha Corporation, Greenwich, Connecticut. Exclusive agents for the British Isles have now been appointed and these are K. S. Paul Ltd., 157 Victoria Street, London, S.W.I. At present, import licenses are required, but it is supposed that in view of the special work that these lubricants can perform, no difficulties will be experienced in this connection.
