Do not mix the engine oil easily and damage the engine    

When there are sales personnel visiting customers to maintain excavators for customers, it is found that some customers are very wrong in order to save costs for excavators to use excavator oil.

For excavators, oil mixed use will aggravate the deterioration of oil, will also lead to slow down or digging action machine high temperature change, accelerate the excavator component wear. So what kind of oil mixing is not advisable?

1. new and old oil can not be mixed

The used oil contains a lot of oxidizing substances. The new lubricating oil is mixed with old oil. The oxidation speed of new oil will speed up, so as to reduce the usage and operation time of new oil. According to the test, it is shown that the service life of the engine oil can reach 1500 hours when the diesel engine's old oil is discarded, and if all the new oil is added to the engine once. If half of the new oil is mixed in half of the old oil, the use of the oil is only 200 hours, and the service life has been reduced a lot.

2. different brands and signs of the oil can not be mixed, will be turbid.

Because of different chemical additives in different brands and different labeling oils, these chemical additives sometimes react, reduce the lubrication effect, produce acid-base compounds, and aggravate the corrosion of engine parts. Now most of the dispersed oil sulfonate detergent, detergent and dispersion of some oil with salicylate. Salicylate is not compatible with Sulfonates used in other lubricants. If the two lubricants mix, there will be stratification, turbidity, and deterioration of cleaning capacity.

Through the above explanation, I believe you have learned why we can't mix the oil of the excavator and what problems will be caused by the combination of the excavator and motor oil, so we must use the specified oil according to the instructions on the instructions.
