Before you obtain an S O S oil sample, operate the engine until the oil is warm and the oil is well circulated. Then obtain the S O S oil sample.In order to obtain a good oil sample, do not take the oil sample from the drain stream. The drain stream method can allow a stream of dirty oil from the bottom of the compartment to contaminate the sample. Likewise, never dip an oil sample from an oil container or pour a sample from a used filter.There are two acceptable ways to obtain S O S oil samples. The following methods are listed in the order that is preferred:
Use an in-line sampling valve on the pressurized oil manifold.
Use a sampling gun (vacuum pump) that is inserted into the sump.Use of the in-line sampling valve is the preferred method. This method provides samples that are less likely to be contaminated. In order to obtain an oil sample from the engine, it may be necessary to increase the engine's speed. Normally, the oil sample is taken at low idle. If the flow rate is too low, increase engine speed to high idle in order to obtain the oil sample.
Do not use the same vacuum sampling pump for extracting oil samples that is used for extracting coolant samples.A small residue of either type sample may remain in the pump and may cause a false positive analysis for the sample being taken.Always use a separate pump for oil sampling and a separate pump for coolant sampling.Failure to do so may cause a false analysis which could lead to customer and dealer concerns.
Oil Sampling Interval
Take the oil samples as close as possible to the standard intervals. In order to receive the full value from S O S oil analysis, you must establish a consistent trend of data. In order to establish pertinent history of data, perform consistent oil samplings that are evenly spaced.
