Lubricating oil has the functions of lubricating, cooling, rust protection, cleaning, sealing and buffering and the operation of various kinds of cars, mechanical equipments can not work without it, so do you want to know more about it?Today let me inform you of some lubricating oil knowledge worthy of learning as much as i can.
As for the choice of lubricating oil, you need to know that your car is natural inhaling car or turbine pressurizing car. It’s also very particular for the choice of lubricating oil of natural inhaling car and turbine pressurizing car. Concerning natural inhaling car, it has a quite low requirement for lubricating oil, mineral oil that has been refined or very good semi-synthetic lubricant is generally used. For turbine pressurizing car, completely synthetic engine oil must be chosen. Besides, oil temperature of engine oil of natural inhaling car is generally within 100, so regular engine oil 30 has already been enough to protect engine. However, turbine pressurizing car is different and completely synthetic engine oil 40 or above is generally needed.
With respect to the replacing of lubricating oil, under normal conditions, most of the cars should be changed oil when generally reaching specified oil change mileage(within 5,000 km), but this number is not necessary because each car has different engine conditions, engine oil using conditions, using environments. When faced with this issue, people should be careful to deal with and make sure everything will be ok when using lubricating oil.
All in all, I sincerely hope that all above information can be useful and helpful to all of you, many thanks!
