[DelAlessandra]

This vehicle requires approximately 4.5 liters of engine oil. When adding oil, be sure to maintain the oil level between the MIN and MAX marks. Engine oil is often referred to as the lifeblood of an engine - without it, the engine cannot operate properly. In an engine, oil performs multiple functions including lubrication, cleaning, sealing, cushioning, rust prevention, and heat dissipation. Here's additional information: 1. Principle: Engine oil, also known as engine lubricant, serves to lubricate moving parts, assist in cooling, provide sealing against leaks, prevent rust and corrosion, and act as a shock absorber. It's rightly called the 'blood' of an automobile. Engine oil consists of base oil and additives. The base oil determines the fundamental properties of the lubricant, while additives compensate for and enhance the base oil's performance characteristics, giving it new properties - making them a crucial component of engine oil. 2. Oil filter function: The oil filter is used to purify the engine oil. Without it, the oil would become contaminated after some use. When purchasing engine oil and oil filters, always buy from authorized channels and choose genuine products from reputable brands.
