How to improve fuel efficiency on my Vauxhall Zafira Life?

I've been noticing that my Vauxhall Zafira Life is not getting the best gas mileage. What can I do to improve its fuel efficiency?

One way to improve fuel efficiency is to make sure your tires are properly inflated. Underinflated tires can reduce your mileage by 0.2% for every 1 psi drop in pressure. Keep them at the recommended pressure listed in your owner's manual. And remember to check them regularly.

Avoid idling your car for extended periods of time. If you're waiting for someone or stuck in traffic, turn off the engine. Idling for just 10 minutes a day can waste up to a gallon of fuel per week. Turning off the engine can save you money and help the environment.

Another way to improve fuel efficiency is to unload any unnecessary weight from your car. The more weight your car is carrying, the harder the engine has to work and the more fuel it will consume. Remove any heavy items that you don't need on a daily basis.
