The requirements for engine oils are as follows: (i) The methyl alcohol or ethyl alcohol is hydrotropic substance which is not easy to be mixed with gasoline; as a result, the combustion may not be complete and the water content of the combustion product will be high which may penetrate into the crankcase and emulsify the engine oil, so excellent emulsion resistance performance is required for the engine oil.
Send the engine oil sample to professional oil testing institution for analysis and testing.
