What is the best way to improve fuel efficiency in my BMW 3 Series?

I've noticed that my fuel consumption is higher than expected in my BMW 3 Series. I want to find ways to improve the fuel efficiency and reduce my gas expenses. What are some helpful tips to achieve this?

First of all, make sure your tires are properly inflated. Underinflated tires can increase fuel consumption. Additionally, try to avoid unnecessary idling and maintain a steady speed while driving. Also, consider using a high-quality synthetic oil for your engine as it can improve fuel efficiency.

Another way to improve fuel efficiency is to reduce the weight in your car. Remove any unnecessary items from your trunk and try to avoid carrying heavy cargo. Additionally, avoid aggressive driving and try to anticipate traffic patterns to avoid sudden braking and accelerating.

Proper maintenance is important for optimal fuel efficiency. Make sure to regularly change your air filter, spark plugs and fuel filter. Also, consider using fuel additives that can clean and protect your engine for better fuel efficiency.
