1.2 FUEL OIL SPECIFICATIONS

1.2.1 Fuel Classification
Since fuel classifications vary among different countries, Niigata has
established the following general specifications. The customer should confirm
his particular fuel oil specifications from the supplier, and should use only
the grade specified by Niigata (or a higher grade).

NOTES: (Fuel Classification)
1. When using a high-viscosity fuel oil having a kinematic viscosity of 30 mm
²
/s
(at 50
℃
) or higher (class C and H), special treatment (heating and
purification) is required. Refer to the following section on "Use of Heavy
Fuel Oil".
2. Vanadium content should not exceed 100 ppm.
3. Kerosene and other fuels lighter than No.2 Diesel should not be used except
under emergency conditions unless prior approval has been obtained from
Niigata. The low viscosity and poor lubricating qualities may damage fuel
injection system components and reduce useful life.
