This paper is a follow-up to Part 1 of the review on European work in the field of engine oil viscosity relevant to the revision of SAE J 300 classification.The European activity covers both low and high temperature aspects and is coordinated within C.E.C., Investigation Groups IGL-8 and IGL-9 respectively.The IGL-8 activity is well under way and results have already been generated in three main areas: The IGL-9 work on high temperature aspects has concentrated on the viscosity measurements of seven multigrade oils in laboratory apparatus at different temperatures and rates of shear, and the results look encouraging. The next immediate step will concern engine testing of the same reference oils in an attempt to generate information on the behaviour of these lubricants in several high temperature engine performance areas. The completion of this work is necessary before attempting any correlation between practical experience and oil viscosity characteristics as defined in one or more laboratory test methods.
