Fuel Oils - Viscosities

Fuels oils - their viscosity versus temperature

Viscosity - Saybolt Universal Seconds SSU,  versus temperature for typical fuel oils are indicated in the diagram below:

fuel oils - viscosity versus temperature

  • TF = TC 9 / 5 + 32
  • SSU (Saybolt Universal Seconds) = Centistokes (cSt) x 4.55
  • 4 - 5000 SSU is the maximum practical limit for pumping
  • 150 - 300 SSU is the atomization range fuel oil no. 5 and 6
