Could low octane fuel help reduce the risk of carbon monoxide poisoning on board a vessel?

Low octane fuel typically burns less efficiently and can produce more unburned hydrocarbons and other pollutants, potentially increasing the risk of carbon monoxide (CO) emissions rather than reducing it. While using a fuel with lower volatility might reduce the likelihood of vapor accumulation, it does not directly mitigate the risk of CO poisoning, which primarily arises from incomplete combustion of any type of fuel. Proper ventilation and maintenance of engines and fuel systems are crucial for minimizing CO risks on board vessels. Therefore, relying solely on low octane fuel is not an effective strategy for preventing carbon monoxide poisoning.
