How does fuel catalyst "Green Plus" of Biofriendly Corp. works?

Answer 1

Green Plus is most likely an oxygenated additive, such as ethanol or propanol. These improve the octane number of gasoline, letting it burn cooler and slower, while at the same time increasing the oxygen content of the tailpipe gases. This means more complete combustion and lower pollution. It usually means gas mileage that's a little worse, too, as the fuel you're burning is already partially burned.
