Oils meeting one grade only, either one of the winter or one of the summer grades ate known as monogrades, containers would be marked SAE 30 or SAE 40 for example. However, it is possible to make an oil, by using certain additives, that will in fact comply with the laiddown limits for one of the winter grades at oop and another grade at the higher temperature of 2100P. The most common of these latter types, multigrades, in South Africa are 20W/SO but it is possible to make, say lOW/50, 20W/40 and several other combinations. Prom experience, the SAE 20W/SO multigrades have been found to be the best for our particular climate. The SAE viscosity markings on the cans relate only to the "flowability" or thickness of the oil and have no bearing on the type of service and the application for which the oil can be used. This is determined by the A.PJ. Service Designations which are also indicated on the cans. The problem of how to indicate the quality and application of oils in some simple way was attacked many years ago by the A.P.I. and they evolved the scheme that is used today, the latest revision dating back to 1972. It simplifies this complex matter in much the same way as the SAE viscosity grades did for viscosity. PETROL ENGINES API SERVICE Oils sold at service stations are usually for Service SE/CC - and reference to the table with the descriptions should indicate fairly readily that such an oil is formulated to the very highest petrol engine requirements and will also be suitable for use in a diesel engine vehicle. In order to qualify an oil to meet the various duties and services certain engine tests have been laid down, each designed to highlight a particular criterion. Par example, one engine test determines the camshaft and follower wear, another measures the piston and piston ring area deposits, another the sludging, and so on. Various sets of tests gradually increase in severity from SA to SE (petrol engines) and CA to CD (diesel engines). Depending on the combination used, it is easy to determine whether the oil you are using is really suitable for the use to which you are subjecting it. In my next article I will deal with some other aspects of Lubricants, and particularly two-stroke oils for the motor cyclists among you. Later on, if your Editor gives me sufficient space we can cover petrol as well.
