How Can I Improve My Volkswagen Passat's Fuel Efficiency?

I own a Volkswagen Passat and I have been noticing that my fuel consumption has been increasing lately. What are some ways to improve my car's fuel efficiency?

One way to improve fuel efficiency is to ensure that your tires are properly inflated at all times. Under-inflated tires can increase fuel consumption.

Regular maintenance of your car, such as oil changes and air filter replacement, can also help improve fuel efficiency.

Avoid idling for long periods of time and try to combine short trips into one longer trip to reduce fuel consumption.
