How can I increase the fuel efficiency on my Audi A3?

I've noticed that my Audi A3 is not getting as good of fuel efficiency as when I first purchased it. What steps can I take to improve its gas mileage?

First, make sure that your tires are properly inflated to the recommended levels. Under-inflated tires can decrease fuel efficiency. Additionally, try to drive at a consistent speed and avoid quick acceleration and braking. These can also negatively affect gas mileage. Finally, consider scheduling a tune-up for your car to ensure that all systems are running efficiently.

Another way to increase fuel efficiency is to reduce the weight of your vehicle. Make sure you're not carrying unnecessary items in your car, as added weight can decrease gas mileage. You can also consider switching to synthetic motor oil, as it tends to improve fuel efficiency. Keeping up with regular oil changes can also help maintain good gas mileage.
