Solution

1. Standard Oil Change Interval

For the BMW 3 Series G20/G21 models, the standard recommendation is to change the oil every 10,000 to 15,000 miles (approximately 16,000 to 24,000 kilometers) or every 12 months, whichever comes first.

2. Severe Driving Conditions

If the vehicle is subjected to severe driving conditions (e.g., stop-and-go traffic, extreme temperatures, towing), consider changing the oil every 5,000 to 7,500 miles (approximately 8,000 to 12,000 kilometers) or every 6 months.

3. Monitor Oil Quality

Regularly check the oil level and quality using the dipstick. If the oil appears dirty or has a burnt smell, it may need to be changed sooner.

4. Use Recommended Oil

Ensure to use the correct oil type as specified in the owner's manual, typically synthetic oil that meets BMW specifications (e.g., BMW Longlife-01).
