Valvoline Diesel Synthetic 5W40 is formulated with high-quality synthetic base stocks and a boosted additive system. The hi-performance synthetic technology meets the stringent demands of modern diesel including EGR (Exhaust Gas Recirculation) engines operating under standard and extended service intervals in a wide variety of service conditions.

Advantages:

• Hi-Performance Synthetic Technology meets the most demanding requirements of modern EGR engines operating at elevated temperatures, higher soot, and higher acid levels in the engine oil.
• Boosted additive chemistry offers extended drain capability in modern diesel engines through exceptional TBN retention, advanced soot control, and outstanding viscosity retention.
• Superior synthetic base stocks provide faster, safer starts during freezing weather and enhanced
  thermal properties for hot weather operations.
• Unique formulation has enhanced fuel economy potential over conventional oils.
• Enhanced valve-train wear protection and reduced oil filter restriction at high soot levels.
• Reduced high-temperature carbon buildup - both single and two-piece pistons - and ring/liner wear protection leads to improved oil consumption control.
• Unique dispersive polymer technology (DPT) provides advanced soot control and outstanding
  engine cleanliness.
• Excellent oxidation, foam, and corrosion inhibition.
• Diesel Synthetic 5W40 provides excellent performance in "mixed fleet" gasoline engines, pickup and delivery, city fleet, long haul over-the-road, and off-highway applications.
