Abstract

The present disclosure relates to a method for making a Universal Tractor Transmission Oil (UTTO) from a Super Tractor Universal Oil (STUO).

Claims

1. A method for making a Universal Tractor Transmission Oil (UTTO) from a Super Tractor Universal Oil (STUO) comprising:

reducing the amount of one or more additive components in the preparation of a STUO to provide a UTTO, wherein the STUO meets the John Deere J20-C performance specification and the Ford M2C134D performance specification.

2. The method of claim 1, wherein the one or more additive components comprises one or more additives selected from the group consisting of an ashless dispersant, a detergent, a corrosion inhibitor, a friction modifier, an antioxidant, an extreme pressure agent, an antiwear agent, an antifoamant, and a defoamant.

3. The method of claim 1, wherein reducing the amount of the one or more additive components comprises reducing the amount of an ashless dispersant by about 5% to about 100%.

4. The method of claim 1, wherein reducing the amount of the one or more additive components comprises reducing the amount of a detergent sufficient to improve the water tolerance of the UTTO.

5. The method of claim 1, wherein reducing the amount of the one or more additive components comprises reducing the amount of a detergent by about 50% to about 100%.

6. The method of claim 1, wherein reducing the amount of the one or more additive components comprises a reducing the amount of a corrosion inhibitor by about 25% to about 100%.

7. The method of claim 6, wherein the corrosion inhibitor is a crankcase corrosion inhibitor.

8. The method of claim 1, wherein reducing the amount of the one or more additive components comprises reducing the amount of friction modifier sufficient to improve wet brake noise.

9. The method of claim 1, wherein reducing the amount of the one or more additive components comprises a reducing the amount of a friction modifier by about 25% to about 100%.

10. The method of claim 1, wherein reducing the amount of the one or more additive components comprises a reducing the amount of an antioxidant by about 25% to about 100%.

11. The method of claim 10, wherein the antioxidant is a high temperature antioxidant.

12. The method of claim 1, wherein reducing the amount of one or more additive components comprises reducing the amount of an ashless dispersant by about 5% to about 100%, the amount of a detergent by about 50% to 100%, the amount of a corrosion inhibitor by about 25% to about 100%, the amount of a friction modifier by about 25% to about 100%, and the amount of an antioxidant by about 25% to about 100%.

13. The method of claim 1, wherein reducing the amount of one or more additive components in the preparation of a STUO to provide a UTTO comprises omitting the one or more additive components.

14. The method of claim 1, wherein reducing the amount of one or more additive components in the preparation of a STUO to provide a UTTO comprises omitting an ashless dispersant, a detergent, and an antioxidant.

15. A UTTO made from the method of claim 1.

16. The UTTO of claim 15, wherein the STUO comprises a major amount of a base oil and a minor amount of an additive concentrate and wherein the UTTO comprises a major amount of a base oil and a minor amount of an additive concentrate, wherein the treat rate of the UTTO additive concentrate is about 40% to about 70% less than the STUO additive concentrate.

17. Use of a UTTO made from the method of claim 1 to lubricate moving parts of a tractor.

18. Use of a UTTO made from the method of claim 1 to lubricate one or more of or all of a transmission, a hydrostatic transmission, a gear-box, a final drive, a hydraulic system, and a wet brake of off-highway mobile equipment.

19. Use of a UTTO made from the method of claim 1 to lubricate one or more of or all of a transmission, a hydrostatic transmission, a gear-box, a final drive, a hydraulic system, and a wet brake of construction equipment.

20. Use of a UTTO made from the method of claim 1 to lubricate one or more of or all of a transmission, a hydrostatic transmission, a gear-box, a final drive, a hydraulic system, and a wet brake of a tractor.

21. A method for making a Super Tractor Universal Oil comprising:

top treating a Universal Tractor Transmission Oil with an aftermarket additive package comprising one or more additives selected from the group consisting of an ashless dispersant, a detergent, a corrosion inhibitor, a friction modifier, and an antioxidant.

22. A Universal Tractor Transmission Oil (UTTO) having improved extreme pressure properties, wherein the UTTO is made from a Super Tractor Universal Oil (STUO) comprising:

reducing the amount of one or more additive components in the preparation of a STUO to provide a UTTO, wherein the STUO meets the John Deere J20-C performance specification and the Ford M2C134D performance specification.

23. A Universal Tractor Transmission Oil (UTTO) having improved brass wear properties, wherein the UTTO is made from a Super Tractor Universal Oil (STUO) comprising:

reducing the amount of one or more additive components in the preparation of a STUO to provide a UTTO, wherein the STUO meets the John Deere J20-C performance specification and the Ford M2C134D performance specification.

24. The UTTO of claim 23, wherein the UTTO is suitable for use in a hydrostatic transmission.

25. A Universal Tractor Transmission Oil having (UTTO) improved friction properties, wherein the UTTO is made from a Super Tractor Universal Oil (STUO) comprising:

reducing the amount of one or more additive components in the preparation of a STUO to provide a UTTO, wherein the STUO meets the John Deere J20-C performance specification and the Ford M2C134D performance specification.
