Scheduled Oil Sampling (S O S)
Refer to the information in the Scheduled Oil Sampling section in this publication regarding the description and specifications for acceptable sampling.Obtain Sample
To compliment a good preventive maintenance program, Caterpillar recommends using S O S at regular scheduled intervals to monitor the condition of your engine, marine gear, and marine gear and engine oil to help determine the maintenance requirements of your engine and marine gear.Normal test results from the oil samples will be used to develop a "baseline" which will be used as a basis for determining the oil change intervals, giving you the ultimate time between oil changes without the risk of engine and marine gear damage.The oil sample should be taken when the oil is warm and well mixed to ensure that the sample is representative of the oil in the compartment.There are several methods used to obtain S O S samples from Caterpillar diesel engines and the marine gear.* Use a sampling gun inserted into the sump.* Use a valve installed for samples.* Use the drain stream method when changing oil.Caterpillar recommends the first two methods. However, if these methods are not possible, then use a drain stream method when changing the oil.If the drain stream method is used to obtain the oil sample, take the sample after some oil has drained and before the final drain oil stream. The oil at the beginning or end of the drain stream is not mixed well enough to be representative of circulating oil in the compartment and may carry debris that can give false S O S analysis results.Refer to How to Take a Good Oil Sample, PEHP6001 for a step-by-step explanation if using this method of sampling oil.Contact your Caterpillar dealer for information and assistance in establishing the S O S program for your engine and application.Oil Drain Intervals
It is essential that an S O S analysis be performed to analyze oil condition before oil change period adjustment is considered. If the engine crankcase oil has reached its condemning limits as established by the oil analysis program, refer to the topic, Engine Oil and Filter(s), in this publication for the procedure to change the crankcase oil and oil filters.Due to manufacturing tolerances, engine application and maintenance variation, all engines do not consume fuel and oil at the same rate. Some history of fuel and oil consumed for each engine (or group of engines) in a similar application must be established.For a group of engines, determine the average fuel consumption and add oil rate. This is performed by multiplying the total quantity of fuel consumed by the operating (service) hours of the engines.For more information on adjusting oil change intervals for specific applications, see your Caterpillar dealer.Engine Oil and Filter(s)
Refer to the Lubricant Viscosity and Refill Capacity chart in this publication for the recommended type and amount of oil to use for this engine.The oil change interval is based on fuel consumption. Use fuel consumption as the best indicator of oil change
