Why are octane levels of US gas so much lower than the rest of the world (e.g. Asia where octane levels are ~97/98/99)?
Is there a reason why the US hasn't adopted these technologies?
There may be various reasons for it. It could be related to the cost of implementing new technologies or simply a matter of preference or convenience. Additionally, there may not be as much of a demand for higher-octane gasoline in the US market compared to other regions.
