How can I increase the fuel efficiency on my Audi A4?

I recently bought an Audi A4 and I've noticed that it consumes a lot of fuel. Is there any way I can increase its fuel efficiency?

Firstly, make sure your tires are properly inflated. Underinflated tires can decrease fuel efficiency. Also, avoid aggressive driving. Rapid acceleration and braking can increase fuel consumption.

Another tip is to use cruise control on the highway. This helps maintain a constant speed and can improve fuel efficiency. Also, check and replace your air filter if it is dirty.

You can also save fuel by avoiding unnecessary idling. If you expect to be stopped for more than 30 seconds, it is better to turn off your engine. And lastly, try to combine errands and plan your route to avoid excessive driving.
