Summary:

Aeration properties of lubricants is an increasing concern as the design of powertrain components, specifically transmissions, continue to become more compact leading to smaller sumps and higher pressure requirements. Although good design practices are the most important factors in mitigating the aeration level of the fluid, the fluid properties themselves are also a contributing factor. This paper investigates the aeration properties of specific base oils commonly used to formulate modern transmission fluids using the General Motors Company Aeration Bench Test found in GMN10060. The test matrix includes thirteen different fluids representing a cross-section of base oil types, manufacturers, and viscosity grades. Per the procedure found in GMN10060, the bench test measures the aeration time, de-aeration time, and percent maximum aeration of the fluid at three temperatures, 60°C, 90°C, and 120°C. In the end, the results are compared with four commercially available transmission fluids
