How do I improve my Vauxhall Combo Life's fuel efficiency?

I have noticed that my Vauxhall Combo Life's fuel efficiency has decreased. What steps can I take to improve it?

Samantha, it is important to regularly check your tire pressure. Under-inflated tires can greatly decrease fuel efficiency. Make sure to inflate your tires to the recommended pressure levels.

Samantha, another factor that can affect fuel efficiency is your driving habits. Avoid unnecessary idling and try to maintain a steady speed when possible. Avoid sudden accelerations and apply gentle pressure on the gas pedal.

Samantha, make sure to get regular tune-ups and oil changes. A well-maintained engine can greatly improve fuel efficiency. Also, consider using high-quality motor oil for better performance.

Samantha, removing unnecessary weight from your vehicle can also help improve fuel efficiency. Clear out any items from your trunk or backseat that you don't need.
