Red Line Oil 15W40 Diesel

Red Line Oil 15W40 Diesel is a full-synthetic ester-based diesel motor oil. It is also sold as diesel engine oil or heavy-duty diesel oil. It is built for diesel engines that need strong wear protection, cleanliness and long drain intervals. The 15W-40 viscosity grade suits light-duty diesel trucks as well as medium and heavy-duty diesel truck engines.

Key Features:

• Full-synthetic ester formula gives high protection, efficiency and cleanliness
• High detergency and acid-neutralizing ability is about double that of conventional petroleum diesel oils, which keeps engines cleaner
• Thermal stability: resists thermal breakdown and oxidation, which helps lubricate hot engine metal
• High natural viscosity index gives a thicker oil film in bearings and cams
• Low evaporation compared with other synthetics improves efficiency and ring seal
• Wear and friction protection across a wide range of operating conditions
• Extended drain intervals add value for long-haul and fleet use
• Compatible with conventional and synthetic motor oils

It suits diesels that run high oil temperatures, such as engines in hot weather or in light trucks that carry or tow heavy loads. Red Line has made synthetic lubricants since 1979. Its products serve the automotive, motorcycle, marine and industrial markets.
