No matter what kind of oil, the following method can be used to check.
(1) Appearance method: check the oil sample taken out, if it is relatively transparent, it shows that the pollution is not serious; If it is foggy, there is water in the oil. If gray, it may be contaminated by lead or other abrasive. If it is black, it is polluted by high temperature exhaust gas.
(2) Diffusion method: drop a drop of 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, the oil has good cleanness. On the other hand, the oil cleaner becomes worse.
