Oil Aeration Measurement
15+ Years of Perfecting Oil Aeration Testing
Our service testing started in 2014 as a study on engine damage caused by air entrainment and cavitation.

Testing oil aeration early in the development process can significantly shorten the timeline for any fluid formulation project.
Our service testing began in 2014 as an investigation into engine damage caused by air entrainment and cavitation. In one study, running an engine with 10% air in the oil revealed how difficult it was to maintain a constant aeration level over time—even under identical operating conditions. We found that air entrainment changes with oil aging, contamination, and more so with different oil specifications, brands, and formulations.
This research made one thing clear: oil aeration is not just an operational byproduct; it is a critical property of the oil itself. The oil aeration often influences the performance of the engine, transmission, or mechanical components it serves.
Lab testing of oil aeration gave us a crucial insight: it allowed us to understand the oil’s aeration behavior independently of any mechanical component. This became a key step before moving on to component-specific testing—and it was our “Aha!” moment. Combined with positive feedback from our customers, it drove us to keep refining our testing prototype.
Today, we work with fluid and additive developers to create low-aeration formulations, and with OEMs to pinpoint how much of a fluid’s aeration level comes from the oil itself versus the component in which it operates.

Oilpas™
Developed in 2007, the Oilpas™ is an optical imaging instrument for oil that introduced a groundbreaking approach to particle measurement in fluid streams. Using advanced image processing software, it accurately measures air bubbles without the complex calibration procedures required by traditional particle counters, making it a faster, simpler, and more reliable solution.
