How can I improve the fuel efficiency of my 2002 Audi A2?

I recently bought a 2002 Audi A2 and I've noticed that it's not getting the best fuel efficiency. Are there any modifications or maintenance tips I can do to improve its efficiency?

First and foremost, make sure you're keeping up with regular maintenance such as oil changes and tire rotations. This can greatly impact your fuel efficiency.

Consider adding a cold air intake or a performance exhaust system to your Audi A2. These improvements can help your engine breathe better and increase power and fuel efficiency.

Check your tire pressure regularly. Under-inflated tires can decrease fuel efficiency, so make sure they're properly inflated.
