Too Little Oil Sample Volume

Victoria Bunchek


What is the correct sample volume to submit for oil analysis?

Doing so provides: 

  • Adequate headspace to homogenize samples 
  • Enough fluid to cover the suite of oil analysis tests 
  • Additional fluid in case any data needs to be verified with a second run 
  • Additional fluid in case ferrographic analysis needs to be performed 

Providing enough sample will prevent delays in getting your results and will also improve the insights you receive, since the information is coming from one sample draw instead of multiple if too little sample were provided.
