No matter what kind of oil, the following methods can be used to check.
(1) Appearance method: check the oil sample taken out. If it is more transparent, it indicates that the pollution is not serious; If it is mist, there is water in the oil; If it is gray, it may be contaminated by lead or other abrasives. If it is black, it is polluted by high temperature exhaust gas.
(2) Diffusion method: drop the oil sample on the filter paper. If the diffusion is very wide and there is no obvious difference between the oil drop area and the diffusion area, it indicates that the oil has good cleanliness. On the contrary, the cleanliness of the oil becomes worse.
