Lubricant compositions
View Patent ↗There is disclosed a lubricating composition comprising a friction modifier and a base oil comprising less than about 3% by weight of tetracycloparaffins. Methods of making and using the composition are also disclosed.
1. A lubricating composition comprising a friction modifier and a non-synthetic base oil comprising less than about 3%, and not 0%, by weight of tetracycloparaffins,
wherein the friction modifier is at least one of a non-nitrogen-containing compound, a nitrogen-containing compound.
2. The composition of claim 1 , wherein the nitrogen-containing compound is a long chain alkylene amine.
3. The composition of claim 2 , wherein the long chain alkylene amine is chosen from N-oleyl-trimethylene diamine, N-tallow-trimethylene diamine, coco-trimethylene diamine, and mixtures thereof.
4. The composition of claim 1 , wherein the nitrogen-containing compound is diethanolamine.
5. The composition of claim 1 , wherein the ash-containing compound is chosen from molybdenum-containing compounds, titanium-containing compounds, and tungsten-containing compounds.
6. The composition of claim 5 , wherein the molybdenum-containing compound comprises sulfur.
7. The composition of claim 5 , wherein the molybdenum-containing compound is chosen from molybdenum carboxylates, molybdenum amides, molybdenum thiophosphates, molybdenum thiocarbamates, and mixtures thereof.
8. The composition of claim 1 , wherein the non-nitrogen-containing compound is a polyolester.
9. The composition of claim 8 , wherein the polyolester is chosen from glycerol monooleate and glycerol monolaurate.
10. The composition of claim 1 , wherein the non-nitrogen-containing compound comprises phosphorus.
11. The composition of claim 10 , wherein the non-nitrogen containing compound comprising phosphorus is a phosphonate.
12. A method of reducing thin-film friction of a fluid between surfaces comprising providing to the fluid a composition comprising a friction modifier and a non-synthetic base oil comprising less than about 3%, and not 0%, by weight of tetracycloparaffins, wherein the friction modifier is at least one of a non-nitrogen-containing compound, and a nitrogen-containing compound.
13. The method of claim 12 , wherein the friction modifier is at least one of a non-nitrogen-containing compound, a nitrogen-containing compound, and an ash-containing compound.
14. The method of claim 13 , wherein the nitrogen-containing compound is a long chain alkylene amine.
