Consumer Benefits
  • Reduced emissions - Formulated with latest generation “low-SAPS” (sulfated ash, phosphorus and sulfur) technology containing reduced levels of metals, phosphorus and sulfur, it maximizes the life of sensitive catalyst metals and the cleaning intervals of diesel particulate filters. 
  • Minimizes maintenance and operating costs - Exceptional soot dispersancy and wear control protects cylinders, pistons, rings, and valve train components against wear and corrosion, promoting optimum service life and minimal maintenance. Contributes to maximum vehicle utilization and minimal downtime 
  • Reduces inventory costs “Universal” formulation provides excellent overall performance in mixed fleets of different engine designs, (including modern low emission diesel engines) allowing one oil for many services and reducing the chance of product misapplication.

Delo® 400 LE Synthetic is specifically designed for the latest low emission diesel engines fitted with Diesel Particulate Filters (DPF), and also those fitted with Selective Catalytic Reduction (SCR) and / or Exhaust Gas Recirculation (EGR) emission control technologies.


The following applications whenever the manufacturer recommends SAE 5W-40 grade:

  • Mixed fleets of diesel engines (high speed, four-stroke, turbocharged or naturally aspirated) 
  • Commercial road transport, including the latest engines fitted with exhaust cleanup devices of all types. 
  • Vehicles meeting the most recent exhaust emissions standards, including US EPA 2002 and 2007, Euro IV, V and VI, and Australian ADR 80/02 (for medium duty) and ADR 80/03 (for heavy duty)
