How to improve fuel efficiency in a Volkswagen Passat?

I recently bought a Volkswagen Passat and I notice that it consumes a lot of fuel. Is there anything I can do to improve its fuel efficiency?

One way to improve fuel efficiency in a Volkswagen Passat is to regularly maintain your car. This includes changing the oil and air filter, keeping the tires properly inflated and having a tune-up.

Another way to improve fuel efficiency is to drive smoothly and avoid sudden acceleration and braking. This will also help to reduce wear and tear on your car's engine.

Consider driving at a constant speed on the highway instead of accelerating and decelerating frequently. This can help save fuel in the long run.

Using the recommended grade of gasoline and avoiding idling for long periods of time can also improve fuel efficiency.
