NOTE: The scope for CAN/CGSB-3.511 was updated by the responsible SDO on September 21, 2021 as the incorrect scope had been inadvertently used for the NOI originally published on October 16, 2019.

This standard 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 approved by

manufacturers to be compatible with oxygenated gasoline containing up to 15 % by volume ethanol. The first

automotive vehicle manufacturer approval of up to E15 occurred in the 2012 model year. Many types of vehicles,

motorcycles, engines, and equipment are not designed for Type B oxygenated gasoline as defined in this standard

and use of such fuel blends could result in unsatisfactory or unsafe operation and engine or equipment damage.

 

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.

 

Some components in fuel distribution systems and on vehicles may not be fully compatible with the two types of oxygenated

gasoline as defined in this standard. Users are advised to consult the owner’s manual or the equipment manufacturer.

 

Provincial, territorial and federal regulations control some parameters included in this standard, and when such

government regulations are more restrictive, they supersede the requirements in this standard.

 

The testing and evaluation of a product against this standard may require the use of materials and/or equipment

that could be hazardous. This document does not purport to address all the safety aspects associated with its use.

Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate

health and safety practices in conjunction with any applicable regulatory requirements prior to its use.
