Abstract
An anti-wear additive composition comprising at least one acid phosphite compound and at least one neutral phosphite compound, wherein the ratio of the acid phosphite to the neutral phosphite is from about 1.0:10.7 to about 2.0:1.0, and lubricating oil compositions containing the same.
Claims
exact text as granted — not AI-modified1 . An anti-wear additive composition comprising:
(a) at least one dilauryl hydrogen phosphate compound; (b) at least one trilauryl phosphite compound; and wherein the ratio of (a) to (b) is from about 1.0:8.5 to about 1.0:0.63.
2 . A method of making an anti-wear additive package comprising:
mixing at least one dilauryl hydrogen phosphite compound with at least one trilauryl phosphite compound; and wherein the ratio of the dilauryl hydrogen phosphite compound to the trilauryl phosphite compound is from about 1.0:8.5 to about 1.0:0.63.
3 . A method of making a lubricating oil composition comprising:
sequentially or concurrently mixing an oil of lubricating viscosity with at least one dilauryl hydrogen phosphite compound and at least one trilauryl phosphite compound; wherein the ratio of the dilauryl hydrogen phosphite compound to the trilauryl phosphite compound is from about 1.0:8.5 to about 1.0:0.63.Join the waitlist — get patent alerts
