The capabilities of new chemistry were evaluated by comparing the performance of an oil formulated with the new additive with those of a commercially available oil. Performance was investigated in the following USS 224 tests:


• Gear Protection Four-Ball Wear (ASTM D 4172), Four-Ball EP (ASTM 02783), Timken Test (ASTM D 2782)


• Corrosion and Oxidation-(Copper Strip) Corrosion (ASTM D 130), USS $-200 Oxidative Thickening, Turbine Oil Rust (ASTM D 665)


e Demulsibility - Demulsibility (ASTM D 1401 and ASTM D 2711)


The commercial oil has proven field performance and is widely used in the industry. The new oil is a cost-effective alternative with improved demulsibility while maintaining good load carrying capacity and wear protection. These properties were produced with an alternative sulphur- phosphorous chemistry and rebalancing of the formulation.


As shown in the table, Four-Ball Wear, Four-Ball EP and Timken test results for the new gear oil are similar to those of the commercially available oil. Wear scar diameter was 0.29 mm, which is well below the 0.35 mm required by USS 224. Load Weld Index (LWJ) was higher than that of the commercial oil. The Timken load was 75 lb, which is above

the minimum specified by USS 224. The results indicate that the new oil can protect gears in the field .


Copper strip, USS 200 and turbine oil rust tests show that both oils passed the corrosion and oxidation tests, indicating that the new oil can provide good corrosion and oxidation performance. Finally, in the ASTM D 1401 test, the new oil completely separated water within 10 minutes, while the commercial oil required 20 minutes. This indicates better demulsibility performance for the new oil.


The ASTM D 2711 test evaluates the resistance to water mixing and the promotion of rapid water separation. Both oils performed well even though the new oil provided slightly better performance. In addition, the new oil performed better than the commercial oil at 54°C, a temperature reportedly of interest to the steel industry.
