Synthetic Diesel Oil

Provides improved wear protection, oxidation resistance, aeration control and viscosity control compared to CJ-4 oils
Formulated with high levels of zinc and phosphorus additives to protect against wear
Resists the effects of extreme heat to help reduce oil consumption
Increased dispersancy helps prevent soot from agglomerating into large, wear-causing particles for excellent engine protection
Provides better cold-flow properties than conventional oils for faster startup protection and improved cold-weather efficiency
