Abstract

A lubricant composition comprising a detergent and a base oil comprising less than about 3% by weight of tetracycloparaffins is disclosed. Methods of making and using the composition are also disclosed.

Claims (20)

1. A lubricant composition comprising a detergent and a non-synthetic base oil comprising less than about 3%, and not 0%, by weight of tetracycloparaffins.

2. The composition of claim 1 , wherein the detergent is a metal-based detergent.

3. The composition of claim 2 , wherein the metal-based detergent comprises a detergent selected from one or more of a neutral sodium sulfonate, an overbased sodium sulfonate, a sodium carboxylate, a sodium salicylate, a sodium phenate, a sulfurized sodium phenate, a lithium sulfonate, a lithium carboxylate, a lithium salicylate, a lithium phenate, a sulfurized lithium phenate, a calcium sulfonate, a calcium carboxylate, a calcium salicylate, a calcium phenate, a sulfurized calcium phenate, a magnesium sulfonate, a magnesium carboxylate, a magnesium salicylate, a magnesium phenate, a sulfurized magnesium phenate, a potassium sulfonate, a potassium carboxylate, a potassium salicylate, a potassium phenate, a sulfurized potassium phenate, a zinc sulfonate, a zinc carboxylate, a zinc salicylate, a zinc phenate, and a sulfurized zinc phenate.

4. The composition of claim 2 , wherein the metal-based detergent is chosen from a calcium sulfonate, a calcium carboxylate, a calcium salicylate, a calcium phenate, and a sulfurized calcium phenate.

5. The composition of claim 1 , wherein the detergent is present in the lubricant composition in an amount ranging from 0.01 to about 0.8 wt. % relative to the total weight of the lubricant composition.

6. The composition of claim 1 , wherein the detergent is present in the lubricant composition in an amount ranging from 0.05 to about 0.6 wt. % relative to the total weight of the lubricant composition.

7. The composition of claim 1 , further comprising antiwear agents, dispersants, diluents, defoamers, demulsifiers, anti-foam agents, corrosion inhibitors, extreme pressure agents, seal well agents, antioxidants, pour point depressants, rust inhibitors and friction modifiers.

8. A method of reducing thin-film friction of a fluid between surfaces comprising providing to the fluid a composition comprising a detergent and a non-synthetic base oil comprising less than about 3%, and not 0%, by weight of tetracycloparaffins.

9. A method of increasing fuel efficiency in a vehicle comprising providing to a vehicle a composition comprising a detergent and a non-synthetic base oil comprising less than about 3%, and not 0%, by weight of tetracycloparaffins.

10. The method of claim 9 , wherein the detergent is a metal-based detergent.

11. The method of claim 10 , wherein the metal-based detergent comprises a detergent selected from one or more of a neutral sodium sulfonate, an overbased sodium sulfonate, a sodium carboxylate, a sodium salicylate, a sodium phenate, a sulfurized sodium phenate, a lithium sulfonate, a lithium carboxylate, a lithium salicylate, a lithium phenate, a sulfurized lithium phenate, a calcium sulfonate, a calcium carboxylate, a calcium salicylate, a calcium phenate, a sulfurized calcium phenate, a magnesium sulfonate, a magnesium carboxylate, a magnesium salicylate, a magnesium phenate, a sulfurized magnesium phenate, a potassium sulfonate, a potassium carboxylate, a potassium salicylate, a potassium phenate, a sulfurized potassium phenate, a zinc sulfonate, a zinc carboxylate, a zinc salicylate, a zinc phenate, and a sulfurized zinc phenate.

12. The method of claim 10 , wherein the metal-based detergent is chosen from a calcium sulfonate, a calcium carboxylate, a calcium salicylate, a calcium phenate, and a sulfurized calcium phenate.

13. An engine, transmission or gear set lubricated with a lubricant composition according to claim 1 .

14. A method of making a lubricant composition comprising combining a detergent and a non-synthetic base oil comprising less than about 3%, and not 0%, by weight of tetracycloparaffins.

15. The method of claim 14 , wherein the detergent is a metal-based detergent.

16. The method of claim 15 , wherein the metal-based detergent comprises a detergent selected from one or more of a neutral sodium sulfonate, an overbased sodium sulfonate, a sodium carboxylate, a sodium salicylate, a sodium phenate, a sulfurized sodium phenate, a lithium sulfonate, a lithium carboxylate, a lithium salicylate, a lithium phenate, a sulfurized lithium phenate, a calcium sulfonate, a calcium carboxylate, a calcium salicylate, a calcium phenate, a sulfurized calcium phenate, a magnesium sulfonate, a magnesium carboxylate, a magnesium salicylate, a magnesium phenate, a sulfurized magnesium phenate, a potassium sulfonate, a potassium carboxylate, a potassium salicylate, a potassium phenate, a sulfurized potassium phenate, a zinc sulfonate, a zinc carboxylate, a zinc salicylate, a zinc phenate, and a sulfurized zinc phenate.

17. The method of claim 15 , wherein the metal-based detergent is chosen from a calcium sulfonate, a calcium carboxylate, a calcium salicylate, a calcium phenate, and a sulfurized calcium phenate.

18. A method for lubricating a machine comprising providing to the machine the lubricant composition of claim 1 .

19. The method of claim 18 , wherein the machine is a gear.

20. The method of claim 18 , wherein the machine is an engine.
