2 Answers
BMW 5 Series N20 engine can add 4.5L of engine oil. Engine Oil: Engine oil, also known as engine lubricant, serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, and shock absorption. It is often referred to as the 'blood' of a car. Composition of Engine Oil: Engine oil consists of base oil and additives. Base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve the shortcomings of base oil, providing certain new properties. Additives are an important part of lubricating oil. Classification of Engine Oil: Currently, engine oils on the market can be simply divided into mineral oil and synthetic oil based on the type of base oil. Synthetic oils can be further categorized into semi-synthetic and full-synthetic engine oils.
Hey, I'm a long-time BMW owner and have been working with the N20 engine for several years. I usually add around 5 liters of oil during each maintenance. Actually, the manual recommends 4.5 to 5.5 liters, depending on the model year and whether the filter is replaced. Buddy, remember not to fill it up all at once—first check the level between min and max using the dipstick or electronic system; overfilling can cause foaming and high oil pressure, damaging the engine. I use 5W-30 synthetic oil with BMW's LL-04 specification and change it every 10,000 kilometers. Also, keep an eye on oil consumption while driving—the N20 engine tends to burn some oil, so check regularly for leaks. In short, adding oil isn't just about pouring it in; safety comes first.
