Abstract

A lubricating oil composition having a wide variety of uses consists of a dearomatized hydrocarbon distillate (petroleum), a post lubricant petroleum hydrocarbon, and white mineral oil. In one embodiment, the dearomatized hydrocarbon distillate is present in an amount from 15 to 25%, the post lubricant petroleum hydrocarbon is present in an amount from 5 to 15%, and the balance is the white mineral oil.

Claims (17)

1. A lubricating oil composition consisting of a petroleum derived dearomatized hydrocarbon distillate, a post lubricant petroleum hydrocarbon, and white mineral oil.

2. The lubricating oil composition of claim 1 , wherein the dearomatized hydrocarbon distillate is present in an amount from 15 to 25%, the post lubricant petroleum hydrocarbon is present in an amount from 5 to 15%, and the balance is the white mineral oil.

3. The lubricating oil composition of claim 1 , wherein the dearomatized hydrocarbon distillate is present in an amount from 19 to 21%, the post lubricant petroleum hydrocarbon is present in an amount from 9 to 11%, and the balance is the white mineral oil.

4. The lubricating oil composition of claim 1 , wherein the lubricating oil composition has a flash point greater than 220° F.

5. The lubricating oil composition of claim 1 , wherein the lubricating oil composition has a flash point of approximately 270° F.

6. The lubricating oil composition of claim 1 , wherein the lubricating oil composition has a dielectric breakdown voltage of 35 KV.

7. The lubricating oil composition of claim 1 , wherein said composition is non-flammable.

8. A lubricating oil composition comprising a white mineral oil based composition, and said composition having flash point greater than 220° F. and a specific gravity at 25° C. of 0.8605.

9. The lubricating oil composition of claim 8 , wherein said composition consists of a petroleum derived dearomatized hydrocarbon distillate, a post lubricant petroleum hydrocarbon, and white mineral oil.

10. The lubricating oil composition of claim 9 , wherein the dearomatized hydrocarbon distillate is present in an amount from 15 to 25%, the post lubricant petroleum hydrocarbon is present in an amount from 5 to 15%, and the balance is the white mineral oil.

11. The lubricating oil composition of claim 9 , wherein the dearomatized hydrocarbon distillate is present in an amount from 19 to 21%, the post lubricant petroleum hydrocarbon is present in an amount from 9 to 11%, and the balance is the white mineral oil.

12. The lubricating oil composition of claim 8 , wherein said composition has a refractive index of 1.4598, an initial boiling point of 450° F., a vapor density of less than 1.0, and a negligible solubility in water.

13. A process for lubricating an object, said process comprising the steps of:

providing a lubricating oil composition consisting of a petroleum derived dearomatized hydrocarbon distillate, a post lubricant petroleum hydrocarbon, and white mineral oil; and

applying said lubricating oil composition to a surface of said object.

14. The process of claim 13 , wherein said providing step comprises providing a lubricating oil composition wherein the dearomatized hydrocarbon distillate is present in an amount from 15 to 25%, the post lubricant petroleum hydrocarbon is present in an amount from 5 to 15%, and the balance is the white mineral oil.

15. The process of claim 13 , wherein said providing step comprises providing a lubricating oil composition wherein the dearomatized hydrocarbon distillate is present in an amount from 19 to 21%, the post lubricant petroleum hydrocarbon is present in an amount from 9 to 11%, and the balance is the white mineral oil.
