実施例1および比較例A及びBの潤滑油組成物について、シーケンスIIIG試験により摩耗、酸化、および堆積制御に関する性能の評価を行った。シーケンスIIIG試験は、高温条件下で油の増粘およびピストン堆積物を測定し、バルブトレーンの耐摩耗性に関する情報を得る試験である。シーケンスIIIG試験は、1996/1997年式231C.I.D.(3800CC)シリーズII、ゼネラルモーターズ社製V−6燃料噴射式エンジンで実施する。無鉛ガソリンを使用し、10分の初期オイルレベリング過程に続き、速度および負荷の条件まで150分の低速ランプでエンジンを作動させる。次に、125bhp、3600rpm、そして150℃の油温で100時間作動させ、オイルレベルを確認するため20時間の間隔で中断する。試験の最後に6個のピストン全てについて堆積物とワニスとを調べ、カムローブとリフターとについて摩耗を測定し、40℃における動粘度の増加を20時間毎に新鮮な基準油と比較し、金属(銅、鉛、および鉄)の摩耗を評価した。シーケンスIIIG試験の合格/不合格の基準は、ILSAC GF−4エンジン油の仕様書に基づき第1表に示す。
