Foam Sequence Testing of Lubricants

Foam sequence testing is a great test for evaluating the form tendency and stability of both new and used oils. Foam and air entrainment can cause all sorts of issues in engines, hydraulics and gearboxes, so understanding how much foam is produced, and how fast it breaks it an essential part of both lubricant formulation and selection.

Hi I'm working in lubricant lab in Iran And I learn many things in your channel Thank you 👍👍👍 You are the best
Great explanation, thanks! So based on the limits that API SN requires, being: 10/0 - 50/0 - 10/0 And comparing to the limits of CI-4 / CK-4: 10/0 - 20/0 - 10/0 Is it correct to say that the Diesel requirement is more stringent to foaming?
Why can't we use the sample which we had tested in sequence 1 for the testing of sequence 2&3 ??? Please let me know the logic behind it.

Sequence III is same sample that was heated to 93C is retested at room temperature at 24C. Its called Seq III.
