How to improve gas mileage on an Audi A4?

I recently bought an Audi A4 and I love everything about it except for the gas mileage. What can I do to improve it?

One of the best ways to improve gas mileage on an Audi A4 is to make sure your tires are properly inflated. Under-inflated tires can decrease your gas mileage by about 0.2% for every 1 psi drop in the average pressure of all tires.

Another tip to improve gas mileage on an Audi A4 is to remove excess weight. The heavier your car is, the more energy it needs to move, which leads to lower gas mileage. Remove any unnecessary items from your car to help improve mileage.
