The truck changed the color of the lubricating oil black, is the car problems, it is encountered bad oil, the reporter today to talk to you about the oil change that thing.

1. it is normal to blacken the engine oil

Now the oil used in general contain clean dispersant, absorb the combustion of carbon deposition and oil oxides, in order to change oil when out, so as to ensure Baotou North rush heavy truck parts, engine internal cleaning. Therefore, the oil has just changed black, not necessarily due to the internal engine is too dirty, as long as the prescribed time oil change. If an oil is not black in use, it shows that the oil does not function properly.

2.10000 kilometers cleaning effect is best

Oil has a strong cleaning capacity. By circulation, it can dissolve the carbide, sludge, metal particles and other foreign matter on the engine parts. The new oil will change from golden to dark yellow in 5 minutes. After 500 kilometers of the car, the engine oil completely turns black. In fact, the quality of the engine oil needs a period of running in period, even if the use of ordinary mineral diesel oil 10000 kilometers travel will achieve the best cleaning effect.

3. using filter paper to detect oil is more scientific

Method for detecting oil touch and smell the often fooled the layman, the real test method is simple and effective, is to test the detection filter (a cat, a treasure collided).

The filter method of use: Parking ten minutes, take a drop of oil dipstick, filter paper in the center position, and then the strip flat in the central hollow object (such as a cup or bowl), waiting for the observation of left oil in the paper on the 5 to 8 hours after the grease spots. The oil from the outside to the inside is divided into oil ring, ring, ring three layer deposition diffusion. The wider the oil ring, the smaller the oil oxidation; the wider the diffusion ring, the longer the oil remaining life; the lighter the color of the deposition ring, the less impurities in the oil.

The boundary of the ring is clear: change as soon as possible

The oil ring disappears, leaving only the sedimentary rings and diffusion rings: change immediately

The only remaining deep color of the sedimentary ring: change immediately, or the engine will be finished!

Oil change period should be suitable, premature or too late is not caused by increased cost, that is, damage to vehicles (low attendance + cost increase)

Baotou beiben heavy truck parts, engine oil drain intervals should be appropriate, too early will cause the waste lubricating oil, will increase the engine wear too late.

Under normal circumstances, the owner can use the mileage and shelf life of the oil to determine whether the need to change.

In the frequent traffic jam or high temperature, cold and other vehicle environment, should shorten the replacement cycle. In addition, if the oil exceeds its expiration date, the mileage should be replaced even if it does not reach the replacement period. If the owners maintain frequent braking, hard acceleration of the bad driving habits, oil change cycle should be in advance, this is because wear bad driving habits tend to accelerate Baotou beiben heavy truck parts inside the vehicle parts.
