摘要

METHOD AND DEVICE FOR MAINTAINING ANTI-WEAR ENGINE LUBRICANT PERFORMANCE USING AN ENGINE-BASED FUEL, AND AN ENGINE LUBRICANT USING A FULL BASE ENGINE The present invention relates to the type of fuel that is used is determined based on an engine control signal. When the fuel is determined to be an alcohol-based fuel, the detected temperature of an engine coolant is compared to a predetermined temperature. When it is determined that the detected temperature is equal to or lower than the predetermined temperature, ethanol is added to the engine lubricant.
