CAN/CGSB-3.519-94

1. Scope 1.1 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 C3, C4 and/or C5 alcohols. They are intended for use in spark ignition engines under a wide range of climatic conditions. 1.2 Some fuel systems may not be fully compatible with fuel produced to this standard. Users are advised to consult the motor vehicle owners' manual or the equipment manufacturer. 1.3 Oxygenated gasoline containing alcohols such as C3, C4 and/or C5 alcohols when being operated under conditions of high load and high speed can exhibit a higher knock tendency than gasoline of equivalent antiknock performance as specified in CAN/CGSB-3.5.
