The invention provides an oil agent for polyacrylonitrile(PAN)-based carbon fiber precursor manufacturing, a manufacturing and use method thereof. The oil agent has excellent stability, the production process is simplified, and at the same time the use effect is not affected. By adjusting the proportion of hydrophilic groups in the whole polysiloxane molecule and the variety, the hydrophilicity can be greatly enhanced and the hydrophilic groups even can be dissolved in water, so that a true solution or microemulsion form oil agent can be obtained. While the stability of the oil agent is greatly improved, the oil agent also facilitates observation of the operation condition of cellosilk bundles in oiling troughs, and the use effect cannot be affected. And high performance PAN precursor and carbon fiber can also be obtained.
