More Information
Summary:An automotive axle includes a housing including gears and a bath lubricating the gears, the bath including gear oil and about 0.1 to 5 wt. % secondary alcohol ethoxylate based on total weight of the bath such that during automotive operation at temperatures less than a threshold, reverse micelles form to trap air bubbles in the bath, emulsifying the bath, and at temperatures greater than the threshold, the reverse micelles dissipate.
