What is the best way to maintain the engine of an Audi A4?

I just bought a used Audi A4 and I want to make sure I am taking care of the engine properly. How often should I change the oil and what other maintenance tasks should I do regularly?

As a car enthusiast, I always recommend changing the oil every 5,000-7,500 miles to keep the engine running smoothly. Additionally, make sure to have the air filter and spark plugs checked and replaced if necessary every 30,000 miles.

In my experience, it is best to follow the recommended maintenance schedule provided by the manufacturer. This usually includes oil changes every 10,000-15,000 miles and other routine checks every 30,000 miles. But always be aware of any unusual noises or changes in performance and bring your car to a mechanic if needed.

To keep your Audi A4 running at its best, make sure to also have the transmission and coolant fluid checked and replaced at the recommended intervals. And don't forget to rotate the tires every 5,000-7,500 miles to ensure even wear.
