How do I properly maintain the Audi A6's engine?

I recently purchased an Audi A6 and I want to make sure I properly maintain its engine. What are some recommended maintenance tips?

The first step in properly maintaining your Audi A6's engine is to regularly change the oil and oil filter. This should typically be done every 5,000-7,500 miles or every 6 months, whichever comes first. Make sure you're using oil that meets the specifications outlined in your owner's manual.

Another important aspect of engine maintenance is to regularly check and top off your coolant fluid. This will ensure your engine doesn't overheat, which can cause serious damage. In addition to checking the levels, make sure you also periodically flush and replace the coolant according to the recommended schedule.
