How to increase the fuel efficiency of a Vauxhall Combo Life?

I am curious about ways to improve the fuel efficiency of my Vauxhall Combo Life. Are there any specific modifications or driving techniques that can help achieve this?

One way to increase fuel efficiency is by regularly maintaining your vehicle, such as changing the oil and air filter.

Another great way is to avoid aggressive driving, such as sudden acceleration and braking, as it can greatly decrease fuel efficiency.

You can also try to reduce the weight of the vehicle by removing unnecessary items from the trunk or backseat.
