Beschreibung
Zusammenfassung:	The present invention comprises: a quantity of a lubricating oil basestock; and a small amount of additive package including (i) a mixture including two or more phosphites and/or phosphates; (ii) one or more thioester compounds; (iii) a detergent including calcium salicylate; and (iv) a poly(alkylene amine)-based ashless dispersant end-capped with a metallocene-catalyzed PAO arm. The present invention may be used to control/reduce wear in at least partially powered transmissions and/or to cool/insulate electrical/electronic components of an at least partially powered drivetrain. 변속기 유체 조성물은 다량의 윤활유 베이스스톡(basestock), 및 (i) 2개 이상의 포스파이트 및/또는 포스페이트를 포함하는 혼합물; (ii) 하나 이상의 티오에스테르 화합물; (iii) 칼슘 살리실레이트를 포함하는 세제; 및 (iv) 메탈로센-촉매화된 PAO 아암(arm)으로 말단 캡핑된 폴리(알킬렌 아민)계 무회(ashless) 분산제를 포함하는 소량의 첨가제 패키지를 함유한다. 이러한 변속기 유체는 적어도 부분 전동식 변속기에서 마모를 제어/감소시키고/시키거나 적어도 부분 전동식 구동계(drivetrain)의 전기/전자 부품을 냉각/절연하는데 사용될 수 있다.
