Can a BMW still be driven if it's one liter short of engine oil?

Generally speaking, a BMW can still be driven even if it's one liter short of engine oil, but it's best to replenish it as soon as possible. Otherwise, prolonged driving with insufficient oil will accelerate engine wear and affect the engine's service life. Below is additional information: Engine oil: The engine oil in a car serves functions such as lubrication, cleaning, and cooling. The amount of engine oil required varies depending on the vehicle model, typically ranging from 4 to 6 liters. When adding engine oil, it's crucial to use the same brand, grade, and type of oil, as using different ones can interfere with the engine's normal operation. Precautions: The engine oil should be replaced every 5,000 kilometers. Generally, gravity oil change is sufficient for this purpose, as it is cost-effective and quick. If the car is used frequently or is relatively old, the oil can be changed every 3,000 kilometers.
Having driven BMWs for over a decade, I know you can't be careless about being one liter low on oil. Check the dipstick markings - if it's near the minimum level, driving slowly in the city to reach the dealership is acceptable. But absolutely no highway driving or aggressive driving! BMW engines have extremely tight tolerances. Insufficient oil will lead to inadequate lubrication for the turbocharger, and piston ring wear is inevitable. Last time my colleague pushed it for 50 kilometers, it resulted in cylinder scoring and a 20,000+ RMB overhaul. In an emergency, you can top up with the same specification oil as a temporary solution, but never mix different brands. Keeping a 1L bottle of oil in the trunk is standard practice - all experienced BMW owners know this.
