Oil droplets trace method take a clean white paper, number of oil drops on the filter paper, after waiting for lubricating oil leakage, if dark look at the surface of the powder, touch resistance acerbity feeling, then impurities inside has a lot of lubricating oil, good oil powder, with the hand feels dry, smooth, and yellow.
Hand twist to lubricating oil twist between thumb and forefinger grinding repeatedly, good lubricating oil hand feel less lubricity, wear debris, no friction, if feel the sand between my fingers, large friction feeling, suggests that the impurity, lubricating oil can no longer use, a new lubricating oil should be replaced.
Illumination method in the sunny day, the lubricating oil with screwdriver lifted, and horizontal Angle of 45 degrees.
Contrast sunshine, observe the oil situation, under the light, can see clearly without wear debris in lubricating oil is good, inheritable effect, if excessive wear debris, lubricating oil should be changed.
Take oil flow observation two cups, one of which need to be checked out of the lubricating oil, empty on the desktop, the other will leave the measuring cup with lubricating oil for high 30 - desktop
40 cm and tilt, let oil flow slowly to the empty cup, to observe its activity, good quality lubricant oil flow should be long and thin, even and continuous, if the oil flow on the fast and slow, and sometimes has a large flow, the said lubricating oil has deteriorated.
