CAN/CGSB 3.511-2005 PDF

This standard applies to four grades of oxygenated gasoline 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.

Some fuel systems may not be compatible with fuel produced to this standard. Users are advised to consult the motor vehicle owner’s manual or the equipment manufacturer.

Oxygenated gasoline containing ethanol, when being used under conditions of high load and high speed, can exhibit a lower antiknock performance than gasoline of equivalent antiknock index as specified in CAN/CGSB-3.5.
