Claims (16)

1. A lubricant composition comprising:

(A) at least one lubricating oil selected from the group consisting of natural and synthetic lubricating base oils;

(B) from 0.5 weight percent to 1.0 weight percent, based on the total weight of the composition, of a mixture of mono-, di-, and tri-nonylated diphenyl amines; and

(C) from 0.5 weight percent to 1.0 weight percent, based on the total weight of the composition, of a blend of N-(hexyl/heptyl)-N′-phenyl-para-phenylenediamine.

2. The composition of claim 1 further comprising at least one additional additive selected from the group consisting of dispersants, detergents, rust inhibitors, antioxidants, metal deactivators, antiwear agents, antifoamants, friction modifiers, seal swell agents, demulsifiers, viscosity index improvers, and pour point depressants.

3. A fuel composition comprising:

(A) at least one motor fuel;

(B) from 0.5 weight percent to 1.0 weight percent, based on the total weight of the composition, of a mixture of mono-, di-, and tri-nonylated diphenyl amines; and

(C) from 0.5 weight percent to 1.0 weight percent, based on the total weight of the composition, of a blend of N-(hexyl/heptyl)-N′-phenyl-para-phenylenediamine.

4. A method of increasing the oxidation stability of a lubricant comprising adding to said lubricant

(A) from 0.5 weight percent to 1.0 weight percent, based on the total weight of the composition, of a mixture of mono-, di- and tri-nonylated diphenyl amines; and

(B) from 0.5 weight percent to 1.0 weight percent, based on the total weight of the composition, of a blend of N-(hexyl/heptyl)-N′-phenyl-para-phenylenediamine.

5. The method of claim 4 wherein the composition further comprises at least one additional additive selected from the group consisting of dispersants, detergents, rust inhibitors, antioxidants, metal deactivators, antiwear agents, antifoamants, friction modifiers, seal swell agents, demulsifiers, viscosity index improvers, and pour point depressants.

6. A method of increasing the oxidation stability of a motor fuel comprising adding to said motor fuel:

(A) from 0.5 weight percent to 1.0 weight percent, based on the total weight of the composition, of a mixture of mono-, di-, and tri-nonylated diphenyl amines; and

(B) from 0.5 weight percent to 1.0 weight percent, based on the total weight of the composition, of a blend of N-(hexyl/heptyl)-N′-phenyl-para-phenylenediamine.
