It offers exceptional resistance to thermal degradation and prevents soot suspension in the oil even with extended drain intervals and increased soot loading. The superior anti-wear agents in this diesel oil extend engine life despite high operating temperatures and extended service intervals. This 1-Qt oil provides added protection against acid build-up and ensures highly reliable performance over a wide range of temperatures, including severe cold.
