Some small engines require a mixture of oil and gasoline evaporates easily what conclusion can be drawn about the polarity engine oil?

Since gasoline evaporates easily, we can conclude that engine oil is non-polar. This is because non-polar substances are those that do not have a net electrical charge, and they are generally composed of molecules that are symmetrical and do not have a strong affinity for water. Gasoline is a non-polar substance, and it evaporates easily because its molecules are not strongly attracted to each other and can easily break away from the liquid and into the air. Engine oil, on the other hand, is a polar substance, meaning that it has a net electrical charge and its molecules are asymmetrical. This polarity causes engine oil to be more viscous and to have a higher boiling point than gasoline, making it less likely to evaporate easily.
