How do I increase fuel efficiency in my Audi A8?

I've noticed that my Audi A8 consumes more fuel than expected. Are there any specific methods or tips I can use to improve its fuel efficiency?

One simple way to increase fuel efficiency in your Audi A8 is to make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency by up to 3%. Regularly checking and inflating your tires to the recommended PSI can save you money on gas.

Another tip is to avoid aggressive driving and excessive idling. This can greatly impact fuel consumption. Instead, try to maintain a consistent speed and use cruise control when possible. Also, turn off your engine if you're going to be parked for more than 1 minute.

Regular maintenance is also crucial in maintaining fuel efficiency. Make sure to follow the recommended service intervals for your Audi A8 and use high-quality fuel and motor oil. This can prevent any potential issues that could impact fuel consumption.
