How do I increase my Audi's fuel efficiency?

I recently purchased an Audi and I noticed that it uses more fuel than other cars I have owned. I want to improve its fuel efficiency, what should I do?

Regularly maintain your Audi by following the recommended service intervals. This includes changing your oil, filters, and spark plugs.

Drive at a steady speed and avoid sudden acceleration and braking. This will help reduce fuel consumption.

Check your tire pressure regularly and ensure they are properly inflated. Under-inflated tires can decrease fuel efficiency.
