耗性（曽田式四球摩擦試験機により測定した耐荷重性磨
耗性径で表す）を調べな、結果を第１表に示す。
［以下余白］ 第１表から明らかなごと（、ＤＯＰを配合しないとき、
（実験番号５〜７）は耐荷重性は向上するが、耐磨耗性
が低下する。しかしＤＯＰを配合するとき（実験番号２
〜４）は耐荷重性がより向上すると共に耐磨耗性も回復
する。更に、有機チタン化合物を添゛加すると潤滑油の
耐荷重性が向上し、特にＤＯＰとの組合わせによりその
効果が頴著となることが分る。
なお、いずれの添加剤も作製３日後においても相分離は
生ぜず、また潤滑油への混合も容易であった。
［発明の効果］ 本発明の添加剤を用いるときは、潤滑油の耐荷重性を向
上せしめることができると共に使用部分の磨耗を防止す
ることができ、摩擦によるエネルギー効率の低下を抑制
することができる。したがって、エンジンなどの動力機
関に使用するときは、出力の増大、騒音の防止、燃費の
削減、部品の寿命の延長などの優れた効果が奏される。
