Quick Tips on Oil Sampling

If you've ever pulled an oil sample, you know there are some things you want to do and other things you would want to avoid in order to get the ideal oil sample. Why does it matter? You want to pull an ideal sample so you can get the best data possible about your equipment and make the right decisions for your equipment.


DO pull the samples once the equipment has been running and is no longer cold. Why? You need the oil to be representative of the oil in your equipment as it runs throughout the day. Drawing it from a machine that has just started up or is “cold” will not give you an accurate sample.


DO pull your samples from the same place in your equipment every time. Why? This way you know your report data always represents the oil from the same spot, so your numbers are comparable.


A few more tips on pulling your sample:

  • If you’re pulling your sample using a vacuum gun, be sure to use fresh tubing for each sample in order to avoid cross-contamination.
  • If you’re pulling your sample from the drain plug, be sure and let the oil drain for a couple of seconds to avoid getting built-up sediment from the bottom of the oil pan in the sample.


DO label your samples consistently. Why? The more information you have, the better. You want to label your samples with the same name every single time. This way you get all the historical data with your samples. Remember, the lab tests thousands of samples per month and they will not know what machine or unit you are pulling the sample from. If you use a new unit name, you’ll start a new file.
