Red Line 21404 Synthetic 15W-40 Four-Stroke Diesel Oil

The 15W-40 synthetic oil serves four-stroke diesel engines, including medium- and heavy-duty trucks. One quart is supplied.

Product details

For four-stroke automotive, motorcycle and marine engines, the synthetic formula uses PE polyol-ester base stocks for wear protection over varied operating conditions. Red Line credits these PE polyol-ester base stocks with the heat stability to withstand modern jet-engine conditions. That thermal stability supports the oil’s automotive, motorcycle and marine use in turbochargers and hot-running engines. Naturally multigrade base stocks reduce the need for large amounts of unstable polymeric thickeners. Medium- and heavy-duty diesel truck use emphasizes durability and improved drain intervals for fleets.
