Kinematic Viscosity Specs & Standards
Specifications:
(viscosities in mm2/s)
Europe Petrodiesel: 2.0–4.5
Europe Biodiesel : 3.5–5.0
US specification of viscosity for low-sulfur No.2 diesel fuel: 1.9-4.1 mm2/s (this is the fuel that is biodiesel is most often compared to)
US Specification for No. 1 diesel fuel is 1.3–2.4 mm2/s.
Most alkyl esters of vegetable oils have kinematic viscosities less than 5.0 mm2/s.
