How to improve the fuel economy of my BMW 3 Series?

I recently purchased a BMW 3 Series and noticed that the fuel economy is not as good as advertised. What steps can I take to improve the fuel efficiency of my car?

First and foremost, make sure your tires are properly inflated. Under-inflated tires can greatly affect fuel economy. Also, consider removing any unnecessary weight from your car. Every extra 100 pounds can reduce fuel efficiency by 1-2%. Additionally, practice efficient driving techniques such as maintaining a consistent speed and avoiding excessive acceleration and braking.

Regular maintenance is key. Make sure to keep up with oil changes and tune-ups as recommended by the manufacturer. A well-maintained engine can improve fuel economy. Also, consider using the recommended fuel grade for your car. Using a higher grade fuel than recommended does not offer any benefits but will cost you more.

Invest in a fuel economy tune-up. This can include replacing spark plugs, oxygen sensors, and other components that directly affect fuel efficiency. Keep track of your fuel economy and if you notice a significant decrease, it may be time for a tune-up.
