Some processes that are used to desulphurize heating fuel oil, if severe enough, can also reduce its natural lubricating qualities. Since fuel pumps on furnaces require the fuel to act as a lubricant, heating fuel oils require sufficient lubricity to give adequate protection against excessive fuel pump wear. Additives can be used to improve fuel lubricity. Lubricity additives can have unwanted side effects particularly when used at excessive concentrations or in combination with other additives or contaminants. Adding over 1% by volume of biodiesel generally results in acceptable lubricity.

C.1.1 The properties of commercial Type 2 fuel oil depend on the refining practices employed and the nature of the feedstocks from which they are produced. For example, Type 2 fuel oil produced within the boiling range of 130°- 400°C may have many possible combinations of various properties such as volatility, density and viscosity.
