Gasoline is primarily composed of octane. With that out of the way: the octane rating of gasoline only has a tangential relationship to the chemical octane. The octane rating is a measure of the resistance of gasoline and other fuels to detonation (engine knocking) in spark-ignition internal combustion engines.It is so named because a fuel composed of 100% iso-octane has an octane rating of 100.uels which are less resistant to detonation have an octane rating lower than 100, fuels that are more resistant to detonation have octane ratings greater than 100. Since ethanol is less explosive and more resistant to detonation than iso-octane, it has an octane rating greater than 100.
In recent years an increased number of cases have been observed in which. chemical compounds are being blended into gasoline that could have a. detrimental effect on engine performance, human health and the environment. The majority of those cases are related to gasoline blends being delivered to. Africa, Middle East and Asia, as Europe and the United States have regulations. in place that partially prohibit the use of these chemicals. Considered to be a cheap source of octane, these chemicals could cause engine. problems, such as corrosion of engine parts, and could affect driving. performance. They are also harmful to human health and to the environment. in the long term when blended and burnt in transportation fuels.
