Abstract
A combination of a fluorosilicone antifoamant and a polyacrylate antifoamant have been found to be effective in reducing foaming of lubricating oils at both low and high temperatures and without degrading the air release time to the extent that would occur with a conventional silicone antifoamant. Neither type of antifoamant is effective in reducing foaming at both low and high temperatures by itself.
