ROA² technology: The cleaning formula for engine efficiency and improved performance

  • Deposits on injectors are broken down and cleaned away

  • Excellent dissolution properties in all (bio-)diesel mixtures

  • ROA² level 2: Ideal for heavy contamination

  • Properties

  • Returns fuel consumption and emission values in the presence of fuel-related soiling to the levels expected of new vehicles

  • Improves combustion, thereby reducing particulate emissions (Euro 6)

  • The active ingredient is activated and works directly in the injection and combustion chamber area

  • Suitable for all (bio)diesel mixtures

  • Application area

  • For all common-rail and pump-nozzle systems

  • For safeguarding general fuel quality

  • Suitable for all (bio)diesel mixtures
