Unless otherwise allowed (see [[#5.4|5.4]] and [[#6.17|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|9.13]]) or mixtures of conventional and synthetic hydrocarbons and may include naturally occurring non-hydrocarbons.  <br>

<h5>'''5.2'''</h5> 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>
