The present invention relates to a honing oil, which comprises the following raw materials by weight: 4-10% of medium-carbon chain chlorinated paraffin, 2-7% of SLN-115 sulfurized fatty acid ester, 3-6% of an extreme pressure agent, 0.5-3% of an anti-friction agent, 1-4% of high base number calcium petroleum sulfonate, 0.1-0.5% of a non-ferrous metal anti-corrosion agent, and the balance of base oil. According to the present invention, the honing oil can effectively prevent the abrasion debris and the oil stone from sticking, and can achieve good lubrication between the oil stone and the work-piece; and the extreme pressure agent, the anti-rust agent and the emulsifier are preferably selected on the basis of the 75SN lubricating oil, such that the honing oil has good cooling ability and good cleaning ability while the anti-oxidation property is improved.
