  • Comparative Example 5 exhibited the same WL as Working Example 1 of 126kgf in the Shell four-ball EP test, but had a lower ISL (63kgf) than that of Working Example 1
  • Comparative Example 6 contained the same components as Working Example 1, but contained lower quantities of additive 1 and additive 2, and failed in terms of
  • Comparative Example 7 contained the same components as Working Example 1, but contained higher quantities of additive 1 and additive 2 and exhibited cloudiness in the storage stability test, and was unsuitable. Because cloudiness occurred, as mentioned above, the other tests were not carried out.
  • compositions of Working Examples 4-8 all contained base oil 1 and additive 1-1, all contained additive 5, and varied in terms of the type and content of additive 2, but all passed in terms of coefficient of friction and flash point, and were found to be suitable.
  • Working Example 9 differed from Working Example 7 by containing additive 1-2 instead of additive 1-1
  • Working Example 10 differed from Working Example 9 by containing base oil 2 instead of base oil 1, but Working Examples 9 and 10 passed in terms of coefficient of friction and flash point, and were found to be suitable.
  • Comparative Example 8 differed from Working Examples 4-8 by containing 0.3 m.cL S S "6 of additive 4 (behenic acid) instead of additive 2
  • Comparative Example 9 differed from Working Examples 4-8 by containing 1.5 m.cL S S "6 of additive 4 (behenic acid) instead of additive 2, but
  • Comparative Examples 8 and 9 underwent precipitation in the storage stability test, and were therefore
  • Comparative Example 10 contained additive 5 in base oil 1, but did not contain additive 1 or additive 2, and passed in terms of flash point, but was found to be - - unsuitable due to exhibiting an extremely high
  • Example 1 passed in terms of coefficient of friction and flash point.
  • Working Example 12 was obtained by adding additive 5 and additive 6 to the composition of Working Example 1, and passed in terms of coefficient of friction and flash point, and exhibited a similar abrasion mark diameter to
  • Working Examples 13-16 were obtained by replacing base oil 1 used in Working Example 12 with other base oils, and all passed in terms of coefficient of friction, and Working Examples 15 and 16 were slightly inferior in terms of flash point, but still passed.
  • additive 3 which is a phosphonic acid ester having a benzene ring, instead of additive 1-1, and failed in terms of coefficient of friction and flash point, and was found to be unsuitable.
