Claims
- 1. A composition of matter comprising a major amount by weight of hydrocracked lubricating oil having susceptibility to deterioration by sunlight and a minor amount by weight, sufficient to inhibit said composition from deterioration caused by sunlight, of at least one added dihydroxy component having a structure ##STR2## wherein each R is independently selected from the group consisting of tertiary alkyl radicals containing up to about 10 carbon atoms, and a and b are integers such that a is equal to at least 2 and the sum of a plus b equals 4.
- 2. The composition of claim 1 wherein said hydrocracked lubricating oil comprises at least about 70% by weight of said composition.
- 3. The composition of claim 2 wherein said added dihydroxy component comprises about 0.005% to about 2.0% by weight of said composition.
- 4. The composition of claim 2 wherein said dihydroxy component comprises about 0.01% to about 1.0% by weight of said composition.
- 5. The composition of claim 2 wherein a is equal to 2 and said dihydroxy component comprises about 0.01% to about 1.0% by weight of said composition.
- 6. The composition of claim 2 wherein each of said R's has the same structure.
- 7. The composition of claim 6 wherein each of the R's is tertiary butyl.
- 8. A method of inhibiting a hydrocracked lubricating oil from deterioration caused by sunlight comprising combining with said oil having susceptibility to deterioration by sunlight an inhibiting amount of at least one dihydroxy component having a structure ##STR3## wherein each R is independently selected from the group consisting of tertiary alkyl radicals containing up to about 10 carbon atoms, and a and b are integers such that a is equal to at least 2 and the sum of a plus b equals 4.
- 9. The method of claim 8 wherein said dihydroxy component comprises about 0.005% to about 2.0% by weight of said composition.
- 10. The method of claim 8 wherein said dihydroxy component is present in an amount equal to about 0.01% to about 1.0% by weight of said composition.
- 11. The method of claim 8 wherein a is equal to 2 and said dihydroxy component comprises about 0.01% to about 1.0% by weight of said composition.
- 12. The method of claim 8 wherein each of said R's has the same structure.
- 13. The method of claim 11 wherein each of said R's is a tertiary butyl radical.
