How to improve fuel efficiency in my Volkswagen Passat?

I have recently purchased a Volkswagen Passat and I am noticing that the fuel efficiency is not as good as I expected. Are there any tips or tricks that I can use to improve my fuel efficiency?

One of the most effective ways to improve fuel efficiency in your Volkswagen Passat is to regularly maintain your vehicle. This includes regular oil changes, checking and replacing air filters, and ensuring that your tires are properly inflated.

Another tip is to practice good driving habits, such as avoiding high speeds and aggressive acceleration. This can greatly impact your fuel efficiency and save you money in the long run.

Consider using a fuel additive or premium gasoline to improve the overall performance and fuel efficiency of your vehicle. It may be a bit more expensive, but the long-term cost savings can be significant.
