Will the 4S shop claim to have changed the engine oil without actually doing it?

4S shops generally do not engage in such practices, as many of them now have monitoring functions. Below is relevant information about engine oil: Functions of engine oil: Also known as engine lubricant, it is hailed as the 'blood' of a car. It serves to lubricate, clean, cool, seal, reduce friction, prevent rust, and protect against corrosion in the engine. Operating temperature of engine oil: The engine is the heart of a car, containing many metal surfaces that rub against each other during operation. These components move at high speeds in harsh environments, with working temperatures reaching 400 to 600 degrees Celsius. Under such extreme conditions, only qualified lubricating oil can reduce wear on engine parts and extend their service life.
