* Use the sampling valve, if installed on the engine, for samples.* Use a sampling gun inserted into the sump. Refer to How to Take a Good Oil Sample, form PEHP6001 for a step-by-step explanation if using this method of sampling crankcase oil.Caterpillar recommends using one of the above methods. If these methods are not possible, then use a drain stream method when changing oil. When using the drain stream to obtain the oil sample, do not sample from the first or final draining. The oil at the beginning or end of the drain stream is not mixed well enough to be representative of the oil in the crankcase. Consult your Caterpillar dealer for complete information and assistance in establishing an S O S program for your 3176 truck engine.
