Features and Benefits

Sasol Diesel 500 offers the following benefits:

  • A high cetane number to minimise ignition delay and thus eliminate engine knock.
  • Cleaner combustion due to its mainly paraffinic composition.
  • Ease of starting and rapid warm-up of cold engines.
  • Adequate lubrication of rotary and in-line diesel injector pumps.
  • Seasonal adjustment of product properties to prevent blockage of in-line filters due to wax crystallisation under low temperature conditions.
