High performance semi-synthetic heavy duty engine oil

Delo ® 400 RDE SAE 10W-30 is a high performance semisynthetic heavy duty engine oil, formulated to conform to current ACEA requirements and top tier OEM specifications for Euro IV and V, and a number of Euro VI diesel engines. Delo 400 RDE SAE 10W-30 is formulated with advanced ISOSYN ® technology combined with a low SAPS additive system designed to offer dependable long drain performance, without compromising durability. Delo 400 RDE SAE 10W-30 is designed for modern low emissions diesel and gas engines, and is recommended for engines with diesel particulate filter systems.

Benefits

  • Designed for viscosity control, and protection against engine wear, corrosion, oxidation, and foaming across extended drain intervals
  • Low SAPS formulation helps protect catalysts and diesel particulate filters in emissions control systems
  • Offers good piston cleanliness, wear and soot control and dependable lubricant stability performance
  • SAE 10W-30 grade is formulated for robust engine wear protection and improved fuel economy
  • Formulated for backwards compatibility, and suitable for a range of vehicles, including older engines

Applications

  • Formulated for use in very severe on-highway naturally aspirated and turbocharged diesel engine operations, and designed for extended drain intervals in combination with low sulphur fuels.*
  • Can be used in trucks and buses equipped with gas engines
  • Designed to provide good performance in diesel particulate filters (DPFs), exhaust gas recirculation (EGR) and selective catalytic reduction (SCR) after treatment systems
  • In Euro VI to I engines, refer to OEM maintenance manual for limitations
  • *Recommendations may differ between engine manufacturers so Drivers Manuals and/or Dealers should be consulted if in doubt
