How to maximize fuel efficiency in my Vauxhall Combo Life?

I recently bought a Vauxhall Combo Life and I'm looking for ways to improve its fuel efficiency. What tips and tricks can you offer to help me save on gas costs and reduce my carbon footprint?

Make sure to keep your tires properly inflated, as under-inflated tires can decrease fuel efficiency.

Avoid idling for extended periods of time, as it wastes gas and emits unnecessary emissions.

Regularly maintaining your vehicle, such as changing the air filter and spark plugs, can also improve fuel efficiency.

Try to avoid heavy acceleration and braking, as it uses more gas than maintaining a steady speed.
