What is the best way to maintain the engine of an Audi car in the long term?

As an owner of an Audi vehicle, I want to know the best practices for maintaining the engine in order to increase its lifespan and performance in the long term. Specifically, I am looking for tips and advice on routine maintenance and care for my Audi's engine.

Regularly change the engine oil and oil filter every 5,000 - 7,500 miles to ensure optimal lubrication and prevent engine wear and tear.

Check and replace air filters every 15,000 miles to keep debris and dirt from clogging the engine and causing damage.
