What is Mazut M100?

Mazut M100 is a heavy residual fuel oil produced to the GOST 10585-99 family of specifications — the bottom-of-the-barrel fraction left after lighter distillates are refined off. It is burned in power stations, district-heating plants, industrial furnaces and large boilers, and used as blending stock for marine bunkers and further refining. Because of its viscosity it is stored and pumped heated, and shipped in heated-coil tankers. Buyers weighing a lighter alternative for smaller boilers can compare Fuel Oil CST-180 or Diesel Gas Oil D2.

Typical specification (GOST 10585-99 type)

ParameterTypical value
Kinematic viscosity at 100 °C≤ 118 mm²/s
Sulphur content (low-sulphur grade)≤ 1.0 – 3.5 % mass per grade
Ash content≤ 0.14 % mass
Flash point (open cup)≥ 110 °C
Pour point≤ 25 °C
Water content≤ 1.0 % vol

The grade (sulphur class) and governing specification for each cargo are fixed in the SCO/FCO and verified by SGS or CIQ at loading; certificates ship with the documents.
