What’s the Oil Capacity for the BMW N55 Engine?

If you’re looking to change the oil in your BMW N55 engine, you might be wondering about the exact oil capacity. Knowing the right oil amount is crucial for optimal engine performance and longevity.

Oil Capacity Overview

For the BMW N55 engine, the oil capacity is generally around 6.5 quarts (about 6.2 liters). This includes the amount needed for the oil filter as well. Always check your owner’s manual or consult a professional to confirm the specifics for your model year, as variations can exist.

Why Oil Capacity Matters

Proper oil capacity ensures that your engine has enough lubrication to function smoothly. Insufficient oil can lead to overheating and increased wear on engine parts, while overfilling can create excess pressure and even cause leaks.

Recommended Oil Types

When you’re changing the oil, it’s also important to consider the type of oil to use. The N55 engine typically performs best with synthetic oils. Here are a few recommendations:

  • BMW Longlife-01 5W-30
  • Castrol Edge 5W-30
  • Mobil 1 0W-40

Additional Tips for Oil Change

  • Check Always: Before starting an oil change, double check to confirm the oil capacity specific to your vehicle.
  • Oil Filter: Don’t forget to replace the oil filter during an oil change; it’s crucial for keeping the oil clean.
  • Dispose Properly: Make sure to dispose of the used oil properly at a recycling center.

Conclusion

Keeping your BMW N55 well-maintained is key to enjoying its performance. Be sure to stick to the recommended oil capacity and type. If anyone has additional insights or experiences with oil changes on their N55s, feel free to share! Your thoughts and tips can help others in the community too.

I heard there are minor differences between models like the 135i and the M235i. Does anyone have info on that?

Yes, the M235i does use slightly more oil due to its performance tuning. It’s usually around 7 quarts, so keep that in mind if you’re checking the levels!

Interesting! I didn’t think there would be such a difference. What about the N55 in the X4? Any ideas?

The X4’s N55 engine also requires about 6.9 quarts, similar to the 335i. But it’s good to always verify because the oil cooler systems can vary.

Good question! Generally, synthetic oils don’t change the required capacity but might improve performance and efficiency.

Does anyone know if using a synthetic oil impacts the capacity needed? I’ve heard mixed opinions on that.

Great advice! I always double-check when changing oil. It saves a headache later!

I always thought it was funny how we measure oil in quarts. Like, who came up with that? Anyway, 6.9 quarts seems to be the sweet spot for most N55s!

Haha! True! But if you don’t keep track, you might end up with engine issues! Better safe than sorry!

I’ve been using 5W-30 synthetic oil, and it works great with my N55. What weight do you guys recommend?

The oil capacity for the BMW N55 engine is around 6.9 quarts (with a filter change). It’s best to use synthetic oil for better performance.

I’ve always stuck with synthetic oils too, but I’ve heard some people have had success with high-mileage conventional oils. Anyone tried that?

I’ve used both synthetic and conventional oils in my previous cars. Honestly, I believe the N55 performs best with synthetic due to the turbo.

I totally agree! Synthetic just holds up better under high temperatures. Plus, have any of you noticed improved engine responsiveness with it?
