operability temperature<br>

lowest temperature at which the fuel oil is designed to provide satisfactory performance under the conditions of storage and use (see 6.23, 6.24 and 9.2).The 2.5 percentile low-end design temperature  is the temperature at or below which 2.5% of the hourly outside air temperatures are observed to occur for an indicated half month. The 2.5% low-end design temperature for most weather stations in Canada by half month period is available on the Canadian Fuels Association Web site (see 2.2). This data is based upon a statistical analysis of hourly weather readings from weather stations across Canada over the thirty year period from 1981 to 2010 inclusive.<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>
