本発明において使用されるジカルボン酸ジエステルは、下記の一般式(1)で表され、一般的には分子内にカルボキシル基を2個有するジカルボン酸と1価アルコールとをエステル化して得られる化合物であり、エンジン油を構成する1種の潤滑油基油である。
その他の合成油系基油としては、一般式(1)で規定する分子量400〜450のジカルボン酸ジエステル以外のジエステル、脂肪酸エステル、ポリオールエステル、コンプレックスエステル、ポリα―オレフィン、ポリブテンなどが挙げられる。
鉱油系基油として、重質油の水素化分解で得られた生成油を水素化脱ロウして得られた100℃における動粘度が4.3mm2/sである基油を用いた。
一般式(1)で表される分子量400〜450のジカルボン酸ジエステル(以下、本発明のジエステルという。)として、100℃における動粘度が3.2mm2/s、分子量が426であるセバシン酸ジオクチルを用いた。
また、本発明のジエステルを満足しない、比較用のジエステルなどとして、100℃における動粘度が3.6mm2/s、分子量が426であるアジピン酸ジイソデシル、100℃における動粘度が2.3mm2/s、分子量が370であるアジピン酸ジオクチル、及び100℃における動粘度が3.4mm2/sであるトリメチロールプロパン(TMP)のヘプタン酸エステルを用いた。
MoDTC:一般式(2)で表され、置換基R4〜R7が2エチルヘキシル基とイソトリデシル基との混合物で、酸素原子と硫黄原子との比Xが1/1のものを用いた。
ZnDTP:一般式(3)で表され、炭化水素置換基R8〜R11がプライマリーC8アルキル基であるZnDTPと、セカンダリーC4/C5のZnDTPとの混合ZnDTP(混合重量=58/32)を用いた。
Caスルホネート:中性カルシウムスルホネート及び過塩基性カルシウムスルホネート
アルケニルコハク酸イミド:高分子量コハク酸イミド及びホウ素変性コハク酸イミド
