How many liters of engine oil should be added to a BMW 320Li?

[LeGemma]

The BMW 320Li with chassis model F35 is a four-door long-wheelbase version equipped with an N20 engine, and its engine oil capacity is 5L. If the engine is being repaired, an additional 1-1.5 liters of oil may be required due to the complete drainage of the engine system and the need for lubrication during assembly. Below are specific details about engine oil: 1. Engine oil refers to the lubricant specifically used in internal combustion engines, which, in addition to lubrication, also serves functions such as cleaning, rust prevention, and cooling. 2. If too much oil is added, it will increase the amount of oil splashed onto the cylinder walls by the crankshaft and connecting rods, increasing the rotational resistance of the crankshaft, reducing engine power output, and increasing fuel consumption. 3. It is advisable to maintain the oil level slightly below the MAX mark on the dipstick. The engine oil dipstick has an upper and lower limit. The normal oil level should be between these two marks.
