This National Standard of Canada applies to four grades of gasoline to which no lead or phosphorus compounds have been added. They are intended for use in spark-ignition engines under a wide range of climatic conditions. This standard is not intended to apply to the mixing of oxygenated gasolines and gasolines, either at the point of retail sale or after the point of retail sale. Gasoline…

This National Standard of Canada applies to two types of oxygenated gasoline, E1-E10 (“Type A”) and E11-E15 (“Type B”), to which no lead or phosphorus compounds have been added, and in which the oxygenate consists essentially of ethanol. They are intended for use in spark-ignition engines under a wide range of climatic conditions. Each type may be supplied in one of four grades which differ in…
