How Can I Improve the Gas Mileage on My Audi A6?

I recently purchased an Audi A6 and have noticed that the gas mileage is not as good as I expected. Is there anything I can do to improve it?

The first thing you should do is make sure your tires are properly inflated. Under-inflated tires can significantly decrease your gas mileage.

Another tip is to avoid idling for long periods of time. If you know you're going to be stopped for more than 30 seconds, it's more fuel-efficient to turn off your engine.

You can also try using cruise control on the highway. This helps maintain a constant speed and can improve your gas mileage.
