How Often Should Full Synthetic Engine Oil Be Changed?

[Craig]

Full synthetic engine oil should be changed every 10,000 kilometers. More details about full synthetic engine oil are as follows: 1. Strictly speaking, full synthetic engine oil refers to high-quality oil products made entirely from PAO or artificially synthesized esters, usually labeled with the word "synthetic" on the oil container. 2. The functions of full synthetic engine oil are as follows: 1) Lubrication and wear reduction. There is rapid relative sliding between pistons and cylinders, as well as between main shafts and bearings. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear. 2) Cooling. Full synthetic engine oil can carry heat back to the oil tank and then dissipate it into the air, helping the radiator cool the engine. 3) Cleaning. Full synthetic engine oil can circulate carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, washing away dirt generated on the working surfaces of the parts through the flow of the lubricating oil.
