HiTEC® 5748

Olefin Copolymer VI Improver


HiTEC® 5748 olefin copolymer viscosity index improver is recommended for use in industrial, gasoline and diesel crankcase lubricants, particularly when excellent shear stability is desired, or as in motorcycle applications. It is based on 23 SSI polymer. Multigrade crankcase oils containing HiTEC® 5748 typically lose no more than 0.5 centistokes (approximately two Saybolt seconds) at 100°C in typical over-the-road service.

Key Performance Benefits

  • Excellent shear stability requirements
  • Field tested
  • Exceeds Bosch stay-in-grade shear stability requirements
  • Surpasses Sequence VIII stay-in-grade requirements
  • Robust low-temperature properties
