How to improve fuel efficiency of an Audi vehicle?

I recently bought an Audi and I have noticed that it consumes a lot of fuel. Is there anything I can do to improve its fuel efficiency?

One way to improve fuel efficiency is to regularly maintain your vehicle. This includes changing the oil, checking tire pressure, and performing tune-ups as recommended by the manufacturer.

You can also try using a fuel additive or switching to high-quality synthetic oil which can help improve fuel efficiency.

Another tip is to avoid excessive idling and use cruise control while driving on the highway. This can help reduce fuel consumption.
