How to improve fuel economy in my Audi A4?

I've noticed that my Audi A4 isn't getting the best gas mileage. What are some tips and tricks for improving fuel economy in my car?

One of the easiest ways to improve fuel economy in your Audi A4 is to keep your tires properly inflated. This can help reduce rolling resistance and improve gas mileage.

Another tip is to avoid idling your car for extended periods of time. Not only does this waste gas, but it also puts unnecessary wear and tear on your engine.
