BMW 320Li with chassis model F35 is the four-door extended version, equipped with the N20 engine, and its engine oil capacity is 5L. Engine Oil: Engine oil refers to the lubricant specifically used in internal combustion engines. Besides lubrication, it also has functions such as cleaning, rust prevention, and cooling. Hazards of Overfilling Engine Oil: If too much engine oil is added, it will increase the amount of oil splashed onto the cylinder walls by the crankshaft and connecting rods during rotation, increase the rotational resistance of the crankshaft, reduce the engine's output power, and increase fuel consumption. Engine Oil Upper Limit: It is advisable to keep the oil level slightly below the MAX mark on the dipstick. The engine oil dipstick has an upper limit and a lower limit. The normal oil level should be between the upper and lower limits.
I've been driving my 320i for several years and know all about engine oil. During regular maintenance, it usually takes about 5 liters for an oil change, mainly because this car has a 2.0T engine with a larger oil capacity. However, there might be slight variations between different model years - for example, older F30 models need around 4.8 liters while newer G20 models require 5.2 liters. The first time I changed the oil myself, I poured in 6 liters and got a yellow warning light on the dashboard - overfilling can cause blue smoke from the engine or even damage the seals. Now I always start with 4.5 liters, run the engine for five minutes to circulate the oil, then check the electronic dipstick function and gradually top up to the mid-level mark. The maintenance manual specifies the exact quantity - don't skip reading it, and remember you'll need an extra half cup of oil when replacing the oil filter.
