What should I do to improve the fuel efficiency of my Vauxhall Combo Life?

I've recently purchased a Vauxhall Combo Life and noticed that its fuel efficiency is not as good as advertised. What steps can I take to improve its fuel efficiency?

Firstly, make sure that you are properly maintaining your vehicle. Regularly check and change your air filter, oil filter, and spark plugs. A well-maintained engine is more fuel-efficient.

Another factor that affects fuel efficiency is your driving habits. Avoid aggressive acceleration and braking and try to maintain a steady speed. This will help you save fuel.

Check your tire pressure regularly. Under-inflated tires can decrease fuel efficiency by up to 3%. Keep your tires at the recommended pressure.

Avoid carrying unnecessary weight in your vehicle. The heavier the car, the more fuel it will consume. Remove any unnecessary items from your car to improve fuel efficiency.
