Why does my Audi A5 engine oil turn black quickly?

I recently bought a used Audi A5 and I noticed that the engine oil turns black within a few hundred miles. Is this normal? How often do I need to change the oil? Are there any additives I can use to prevent this? Thanks in advance for your advice.

It is normal for the engine oil to turn black quickly in an Audi A5. The high performance engines in Audi cars tend to produce more carbon deposits, which is what causes the oil to turn black. As for how often you should change the oil, it is recommended to do so every 5,000 miles or once a year, whichever comes first.

To prevent the oil from turning black quickly, you can try using an oil additive that is specifically designed for high performance engines. This can help reduce carbon buildup and keep your engine running more efficiently. Just make sure to follow the manufacturer's instructions when using any additives.

Another possible reason for the black oil could be that the previous owner did not perform regular oil changes or used low quality oil. In this case, it may be a good idea to get an engine oil flush to clean out any deposits and start fresh. As for the frequency of oil changes, it is always best to follow the recommendations in your owner's manual.
