このようなコンプレッサーに使用される潤滑油組成物は、各成分を充分に潤滑するため、要件の組合わせに適合しなければならない。
Lubricating oils can be exposed to high temperature conditions in the lubrication of compressors, particularly rotary air compressors.
Lubricating oil compositions used in such compressors must meet a combination of requirements in order to adequately lubricate each component.

したがって、この種のコンプレッサーでは油の変化に対する必要性を最小化可能にする、即ち、油の排出間隔を好適化するには、このような潤滑油組成物は、良好な沈着制御性ばかりでなく、良好な熱・酸化安定性も示さなければならない。
