How to increase the fuel efficiency of Vauxhall Combo Life?

I recently purchased a Vauxhall Combo Life and noticed that it consumes a lot of fuel. Is there any way to improve its fuel efficiency? Any tips or advice would be greatly appreciated.

Maintain your Vauxhall Combo Life regularly by following the manufacturer's recommended service schedule. Regular maintenance will ensure that your vehicle runs efficiently and consumes less fuel.

Avoid aggressive driving, such as speeding and rapid acceleration. This can greatly reduce your fuel efficiency. Drive at a steady speed and use cruise control when possible.

Check your tire pressure regularly. Under-inflated tires can decrease fuel efficiency by up to 3%, so make sure your tires are properly inflated.

Reduce the weight in your Vauxhall Combo Life by removing unnecessary items from the trunk and roof rack. The less weight your car has to carry, the less fuel it will consume.
