How to improve gas mileage on my Audi A1?

I have noticed that my Audi A1's gas mileage is not as efficient as it used to be. Is there anything I can do to improve it?

One possible solution is to make sure your tires are properly inflated. Underinflated tires can cause your car to use more gas.

Another helpful tip is to avoid quick starts and stops while driving. This can also use up more gas.

Regular maintenance, such as getting an oil change and replacing air filters, can also improve your gas mileage.
