Excellent thermal stability, oxidation resistance, and an unequalled ability to lubricate hot metal make Red Line High-Performance 15W40 Diesel Engine Oil a wise choice for turbocharged and highly stressed engines. Red Line says this oil provides 25-50 percent less evaporation than most other synthetics and 50-75 percent less than petroleum-based oils for better sealing, reduced oil consumption and wear, and improved engine efficiency.
