  • Publication number: 20190185773
    Abstract: Provided is a composite additive for fuel capable of significantly delaying a phase separation phenomenon even in poor environmental conditions such as high humidity, low temperature, storage for a long period of time, and the like, preventing freezing in winter due to a lower freezing point, and having an excellent cleaning effect on impurities fixedly adhered in an engine. Further, the composite additive for fuel may prevent fuel from being used for purposes other than as a fuel, for example, as a drink, and avoid causing fatal problems.
