Viscosity: CST 180 denotes centistoke (cst) at 180 degrees Celsius. It shows the fuel oil’s kinematic viscosity at this particular temperature. Fuel oil with CST 180 has a lower viscosity than fuel oil with CST 380.
Common utilize: Medium-sized ships and other vessels frequently utilize CST 180 fuel oil in their engines. It supplies the energy required for onboard systems and propulsion.
