How can I improve my gas mileage on my Audi A6?

My Audi A6 is a few years old now and I feel like I'm having to fill up my tank more often than before. Is there anything I can do to improve my gas mileage? Any specific maintenance or driving techniques I should follow?

To improve your gas mileage, make sure to regularly check and replace your car's air filter. A clogged filter can reduce fuel efficiency by up to 10%. In addition, try to accelerate and brake gently and avoid idling for extended periods of time.

I recommend investing in a fuel injector cleaner to improve your gas mileage. It helps clean any deposits that may have built up over time, leading to better fuel economy. Also, try to keep your tires properly inflated and use cruise control on the highway.

Check your tire pressure regularly and make sure they are properly aligned. Underinflated tires can decrease gas mileage. Also, consider using a higher quality fuel and conducting regular oil changes to keep your engine running efficiently.
