Regular oil changes can greatly benefit engine life
The main function of oil is to lubricate, clean and dissipate heat. You will say that I have used ordinary oil for more than 10,000 kilometers without finding any problems, but after a long time, you will find that your engine life is tens of thousands of kilometers shorter than others. The same If you turn on the engine after the mileage, you will find that other people's engine block, the inner wall of the cylinder head is only yellow, but yours is a layer of black sludge. When someone else changes the oil for 5,000 kilometers, the oil is still translucent, and you are completely black. , Blackening is dirty, affecting lubrication, let alone cleaning, and the heat dissipation capacity is much worse.
After 5000, there will be some metal dust in the oil pan that can be seen with the naked eye. In addition, you sediment the waste oil for 24 hours to see if there is also a little metal debris at the bottom?
You bought your car for more than ten or two hundred thousand dollars. When it comes time to change the oil, you feel distressed for the hundreds of dollars, but let the car lubricate with this kind of oil containing metal debris, you can't feel it, your car Can't feel it yet? Don't scold the manufacturer just because you feel bad for these hundreds of dollars, your car will not run before the overhaul period.
