What is the most important maintenance task for an Audi A8 engine?

I'm a new owner of an Audi A8 and I want to make sure I'm taking good care of the engine. What is the most important task I need to do regularly to keep it in good condition?

Regular oil changes are crucial for maintaining the health of your Audi A8's engine. The manufacturer recommends changing the oil every 10,000 miles or once a year, whichever comes first. Make sure to use high-quality synthetic oil for optimal performance.

In addition to oil changes, it's important to replace the air filter regularly. A clogged air filter can restrict airflow to the engine, leading to reduced performance and potentially even engine damage. Check your owner's manual for the recommended replacement interval.
