How to properly maintain the engine of a Audi 80?

I recently purchased a used Audi 80 and I want to make sure I'm taking proper care of the engine. What are some important maintenance tasks I should be doing regularly? Can I do them myself or should I take it to a mechanic?

Regular oil changes are crucial for keeping your Audi 80's engine running smoothly. It's recommended to do this every 5,000 miles or every 6 months, whichever comes first. You can either do it yourself or take it to a trusted mechanic.

Make sure to check your coolant levels regularly and top off if needed. This helps prevent your engine from overheating. You can easily do this yourself by following the instructions in your owner's manual.

Replacing your air filter every 12,000 miles is also important for maintaining your engine's performance. This is a simple task that you can do yourself with the help of a tutorial or take it to a mechanic.
