（３）耐銅腐食性試験
ＪＩＳ Ｋ２５１４－１：２０１３に準拠するＩＳＯＴ試験にて、試験油に触媒である銅板を加えて、油温１７５℃、試験時間４８時間の条件にて試料油を劣化させた。劣化後の試料油について、ＪＰＩ－５Ｓ－３８に準拠し、銅の溶出量（質量ｐｐｍ）を測定した。銅の溶出量が少ないほど、耐銅腐食性は高い潤滑油組成物であるといえる。本実施例では、銅の溶出量が１００質量ｐｐｍ以下であることを、耐銅腐食性の合格基準とした。 (3) Copper corrosion resistance test In the ISOT test conforming to JIS K2514-1: 2013, a copper plate, which is a catalyst, is added to the test oil, and the sample oil is deteriorated under the conditions of an oil temperature of 175 ° C and a test time of 48 hours. let me Regarding the sample oil after deterioration, the copper elution amount (mass ppm) was measured according to JPI-5S-38. It can be said that the lubricating oil composition has higher resistance to copper corrosion as the amount of eluted copper is smaller. In this example, the acceptance criterion for copper corrosion resistance was that the amount of copper eluted was 100 ppm by mass or less.

In this example, the acceptance criterion for copper corrosion resistance was that the amount of copper eluted was 100 ppm by mass or less.
表１より、実施例１で調製した潤滑油組成物は、成分（Ａ）～（Ｆ）を含有しているため、耐焼き付き性、クラッチ特性、及び耐銅腐食性がバランス良く良好であった。一方で、比較例１～５で調製した潤滑油組成物は、成分（Ｂ）～（Ｆ）のいずれか一つを含有しておらず、耐焼き付き性、クラッチ特性、及び耐銅腐食性の少なくとも１つが劣る結果であった。例えば実施例１と比較例２を対比すると、非ホウ素変性コハク酸イミドを含まない比較例２に比べて、非ホウ素変性コハク酸イミドを含む実施例１は、耐焼き付き性を良好に保持しつつも、クラッチ容量が向上し、さらに耐銅腐食性も向上していることが分かる。
From Table 1, since the lubricating oil composition prepared in Example 1 contains components (A) to (F), seizure resistance, clutch characteristics, and copper corrosion resistance are well balanced. . On the other hand, the lubricating oil compositions prepared in Comparative Examples 1 to 5 do not contain any one of the components (B) to (F), and have excellent seizure resistance, clutch properties, and copper corrosion resistance. At least one was an inferior result. For example, when Example 1 and Comparative Example 2 are compared, Example 1 containing non-boron-modified succinimide maintains good seizure resistance as compared to Comparative Example 2 which does not contain non-boron-modified succinimide. Also, it can be seen that the clutch capacity is improved and the copper corrosion resistance is also improved.
