Red Line Diesel Engine Oil is highly resistant to thermal breakdown. This 15w40 diesel-specific oil provides double the detergent and acid-neutralizing ability of conventional petroleum diesel engine oils for maximum engine cleanliness.
This oil is ideal for diesels that run high oil temperature, such as those operated in hot weather or those in light truck applications where heavy loads are carried or towed. Best choice in medium and heavy-duty diesel truck engines when maximum durability is required. When used at extended drain intervals, it is an excellent value for long-haul, fleet use.
- High detergency allows extended drain intervals and provides increased cleanliness
- Improved fuel economy and ring seal for more power
- Superior high-temperature stability and oxidation resistance
- High natural viscosity index (VI) provides thicker oil film in bearings and cams
- Less evaporation than other synthetics for improved efficiency and ring seal
- Recommended for API CJ-4/CI-4 Plus/CI-4/CF/CH-4/CF-4
