Unless otherwise allowed (see 5.4 and 6.17), the heating fuel oils shall consist of conventional hydrocarbons (i.e. petroleum-derived from natural gas liquid condensates, crude oil, heavy oil, shale oil and oil sands), synthetic hydrocarbons (see 9.13) or mixtures of conventional and synthetic hydrocarbons and may include naturally occurring non-hydrocarbons.  <br>

'''5.2''' The heating fuel oils may contain additives designed to improve the characteristics or performance of the fuel oil. Additives include those that enhance low-temperature flow properties, storage life, static charge dissipation, water haze dissipation, lubricity and inhibit corrosion.<br>

'''5.4''' In Types 0, 1 and 2 fuel oils, there shall be no intentional addition of used lubricating oils, used solvents, triglycerides (such as raw vegetable oils, animal fats, fish oils or used cooking oils), or other fluids which are not normal components of the fuel. Types 4, 5 and 6 fuel oils may contain used lubricating oils or other fluids provided that the fuel oil is used in specifically designed equipment and the relevant authority approves their use.<br>

There are two exceptions (see [[6.3]] and 6.17).<br>
