Is it necessary to use premium gas in a Vauxhall Grandland?

I just bought a Vauxhall Grandland and I'm wondering if it's necessary to use premium gas for optimal performance and fuel efficiency. I've heard mixed opinions on this.

Yes, it is recommended to use premium gas for best performance and fuel efficiency in your Vauxhall Grandland. This will provide a smoother ride and better engine performance.

It's not necessary to use premium gas, however, it might improve the overall performance and longevity of your Vauxhall Grandland. If you can afford it, it's worth using.

There isn't a significant difference in performance or fuel efficiency between regular and premium gas in a Vauxhall Grandland. Unless your vehicle is specifically designed for premium gas, stick with regular.
