How do I improve fuel economy on my 2023 Audi A4 Technology

So I’ve been driving my 2023 Audi A4 technology for the past 2years in Pune and Mumbai and I’ve been consistently getting the average of 6-7Kmpl short term range and 7-8kmpl long term range which is quite critical when it comes to driving 3000-4000 kms every month. Hence I’m here, eagerly looking for tips and tricks right from which fuel type to use, to tyre pressure and anything that can help me get the best mileage and efficiency from my car !
