What is the best way to increase fuel efficiency in the Vauxhall Combo Life?

I have noticed that my Vauxhall Combo Life has been using more fuel than expected. What steps can I take to improve its fuel efficiency?

One of the most effective ways to increase fuel efficiency in your Vauxhall Combo Life is to practice good driving habits. This includes avoiding aggressive acceleration and braking, maintaining a steady speed, and avoiding excessive idling.

Regular maintenance is also crucial for improving fuel efficiency. Be sure to keep up with oil changes, regularly check and replace air filters, and ensure your tires are properly inflated.

In addition, you can try using a fuel additive to help clean and improve your engine's performance. This can lead to better fuel efficiency and a smoother drive.
