How do I improve the fuel efficiency on my Audi A6?

I recently purchased an Audi A6 and I've noticed that it's not getting the best gas mileage. What can I do to improve its fuel efficiency?

First, make sure you're following your Audi's specific maintenance schedule. Regular oil changes, tire rotations, and air filter changes can all improve your fuel economy.

You should also check your tire pressure regularly. Underinflated tires can lower your fuel efficiency by up to 3%. Keep them properly inflated according to your owner's manual.

Another tip is to avoid excessive idling or stop-and-go driving. This can waste fuel quickly. Try to plan your route in advance to avoid traffic and use cruise control on the highway.
