Illustration 1 g00408438The Oil Renewal System (ORS) meters engine oil that is blended into the fuel supply. This oil will be consumed by the engine during the process of combustion. Normal operation will continually lower the oil level in the crankcase. Continually adding new engine oil will allow the life of the oil to be extended. An S O S analysis will determine if the oil needs to be changed.The graph in Illustration 1 plots the quantity of added oil against the service hours during a 500 hour period. This data can be used to determine if the Oil Renewal System is working properly. Keeping a daily maintenance log of all of the additions of oil is necessary for the accuracy of this data. The daily maintenance log is also necessary for adjustment of the metering rate. The daily maintenance log will also indicate the total amount of oil that has been added since the last oil change. This information is needed at the time of each S O S analysis.Note: Log the additions of engine oil to the crankcase and the additions of engine oil to the makeup oil tank.
