How to keep my Audi's engine in good condition?

My Audi's engine seems to have some issues lately, what can I do to keep it in good condition?

First of all, make sure you are regularly changing your oil and oil filter according to the manufacturer's recommendations. Also, keep an eye on your coolant levels and make sure they are topped off when it's needed. Additionally, pay attention to any strange noises or vibrations and get them checked out by a certified mechanic. It's always better to catch potential issues early on, rather than waiting for them to become bigger problems later on.
