What is the best way to increase fuel efficiency in a Vauxhall Grandland?

I recently purchased a Vauxhall Grandland and I'm looking for tips on how to improve its fuel efficiency. I've heard conflicting advice, such as using premium fuel or keeping tire pressure high. Can anyone offer any advice on the most effective methods?

I have found that keeping the tire pressure at the recommended level and using premium fuel do indeed improve fuel efficiency.

In my experience, it's also important to avoid rapid acceleration and excessive idling, as these can really drain your gas tank.

Have you considered investing in a hybrid or electric model? These tend to have much better fuel economy.
