Octane

Octane is a volatile and highly flammable component of gasoline of petrol. An octane rating or number is a standard measure of the fuel (or engine’s) performance. The higher the fuel’s octane number, the more powerful and fuel-efficient the engines would be. Australia’s current standard is 91 octane number for unleaded fuel with some additional requirements. Raising the standard octane number would mean requiring cleaner and more efficient fuel.
