| description | To provide the lubricant composition and the method for using the lubricant composition, wherein the lubricant composition has high sustainability of an effect of suppressing deposit formation that can occur in a compressor, and can maintain high efficiency of the compressor for a long time, when used in a diesel engine equipped with a turbocharger with a compressor outlet temperature of 190°C or higher.SOLUTION: The lubricant composition for use in the diesel engine equipped with the supercharger comprises a base oil (A) containing poly-α-olefin (A1) and a viscosity index improver (B) with a SSI (shear stability index) of 20 or less, wherein a distillate content of light fractions at 496°C or less in a gas chromatographic distillation test is less than 80% by volume.SELECTED DRAWING: None
【課題】コンプレッサー出口温度が１９０℃以上と高温となる過給機を搭載するディーゼルエンジンに用いた場合において、コンプレッサー内に生じ得るデポジット形成の抑制効果の持続性が高く、コンプレッサーの高い効率性を長時間維持し得る潤滑油組成物、及び当該潤滑油組成物の使用方法を提供する。【解決手段】過給機を搭載するディーゼルエンジンに用いられる潤滑油組成物であって、ポリ−α−オレフィン（Ａ１）を含む基油（Ａ）と、ＳＳＩ（せん断安定性指数）が２０以下である粘度指数向上剤（Ｂ）とを含有し、ガスクロマトグラフ法蒸留試験における４９６℃以下の軽質留分の留出量が８０容量％未満である、潤滑油組成物。【選択図】なし |
