TAKING SAMPLES - GUIDELINES & BEST PRACTICES

Oil analysis is only as good as the sample taken. The goal is to take samples that are truly representative of the oil in the engine. Remember the old saying: Garbage in, garbage out.

• When to sample? Take samples during operation or within 30 minutes of shutdown.



• Where to sample? We recommend an oil galley, the engine crankcase, the drain plug or dipstick tube. Do not take samples from the oil filter or drain pan. Draw from the middle of the reservoir to avoid any sludge at the bottom.



• Be consistent. Take samples from same location every time. Consistency is key.



• Do not overfill the sample container. We recommend three-quarters full.



• Cleanliness counts. Make sure that the sample container is totally clean and dry before use. Do not re-use tubing, pumps, probes or dirty rags. Test results are often measured in parts-per-million, so the container should be as clean as possible.



• Close tightly. Seal the container securely to prevent any contamination or loss of oil during transit.



• Fill it out. Fill out the sample information label accurately and completely.



• Wrap it up. Wrap the sample information label around each sample container, and attach with a rubber band.



• Send right away! Mail, courier or deliver your samples to us immediately so we can return your results as soon as possible.
