Oxygenated automotive gasoline containing ethanol (E1-E10 and E11-E15)

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 anti-knock index (octane rating).

Type B oxygenated gasoline in this standard is intended for use in automotive vehicles that are compatible with oxygenated gasoline containing up to 15% by volume ethanol (see 9.6).

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.
