Is the engine oil for new cars specifically designed for the break-in period?

[LeJosephine]

New car engine oil is specifically designed for the break-in period to ensure that all components of the engine can fully adjust and break in during this phase. It not only offers superior fluidity and heat dissipation but also contains special grinding additives to aid in the break-in process. Below are the functions of engine oil: Lubrication to reduce wear: There is rapid relative sliding between the piston and cylinder, as well as between the crankshaft and bearings, which can easily lead to wear. High-quality engine oil forms a sufficiently thick oil film between these sliding surfaces, separating the parts and reducing wear. Cooling: Engine oil helps cool the engine by carrying heat back to the oil pan and then dissipating it into the air, assisting the radiator. Cleaning: Good engine oil can circulate carbon deposits, sludge, and metal wear particles back to the oil pan, flushing away contaminants from the working surfaces of engine components through the flow of the lubricant.
