When it comes to maintaining your BMW 428i Gran Coupe, understanding the oil specifications and requirements is crucial. The right oil ensures optimal engine performance, longevity, and efficiency. Let's explore the recommended oil specifications for your beloved BMW 428i Gran Coupe.

1. Oil Viscosity

BMW recommends using synthetic oils with a specific viscosity grade for the 428i Gran Coupe series. The optimal oil viscosity for this model ranges from 0W-30 to 5W-40, depending on the climate conditions you drive in.

For colder temperatures, it is advisable to opt for lower viscosity oils such as 0W-30 or 0W-40, as they provide better cold-start protection and lubrication. In warmer climates, oils with higher viscosity ratings, such as 5W-30 or 5W-40, are more suitable.

• BMW Longlife-01: This specification ensures superior engine protection, improved fuel efficiency, and reduced emissions. It is suitable for both gasoline and diesel engines.
• API SN: This American Petroleum Institute certification signifies that the oil meets the standards for gasoline engines, including excellent wear protection, thermal stability, and resistance to deposits.
• ACEA A3/B3 or A3/B4: These European Oil Sequences are designed to meet the requirements of high-performance gasoline and diesel engines, providing better lubrication and emission control.

3. Oil Change Interval

It is crucial to follow the recommended oil change intervals provided by BMW to maintain optimal engine performance. Typically, BMW recommends changing the oil in the 428i Gran Coupe every 7,500 to 10,000 miles or approximately once a year, depending on driving conditions and oil grade used. Regularly checking the oil level using the dipstick is also essential to ensure it remains within the recommended range.
