How much engine oil does a 3 series BMW need?

I can't give you an exact amount of engine oil for a 3 Series BMW without knowing more about your specific car. The oil capacity varies depending on the model year, engine size, and even the specific engine code.

Here's how to find the correct oil capacity for your BMW 3 Series:

1. Check your owner's manual: This is the most reliable source for information about your car, including the recommended oil type and capacity.

2. Look at the dipstick: The dipstick shows the current oil level. If it's full, you don't need to add oil. If it's low, consult your owner's manual for the correct amount of oil to add.

3. Consult online resources: Websites like BMW's official site or other reputable automotive websites may have information about your specific 3 Series model's oil capacity.

4. Contact a BMW dealership or a qualified mechanic: They can provide you with the exact oil capacity for your vehicle.

Important Note: Be sure to use the correct type of engine oil recommended by BMW for your vehicle. Using the wrong oil can damage your engine.
