How to maintain the Vauxhall Grandland's fuel efficiency?

I have recently purchased a Vauxhall Grandland and I want to ensure that it maintains its fuel efficiency. What are some tips and tricks I can follow?

Regularly service your car to ensure all components are working efficiently. This also includes changing your oil and air filter regularly.

Maintain proper tire pressure as underinflated tires can decrease fuel efficiency.

Avoid aggressive driving and try to maintain a consistent speed on the highway.

Make sure to properly tighten your gas cap to prevent any fuel from evaporating.
