Should I use premium fuel for my Vauxhall Insignia?

I just bought a Vauxhall Insignia and I am wondering if I should use premium fuel for it. I have heard conflicting opinions about this and I want to make sure I am doing the right thing. Could someone give me some advice on this?

It is not necessary to use premium fuel for your Vauxhall Insignia. Most modern cars are designed to run on regular unleaded fuel, so unless your owner's manual specifically states otherwise, regular unleaded is perfectly fine.

Premium fuel may provide some slight performance benefits for your Insignia, but unless you are driving a high-performance vehicle, the difference will not be noticeable. Stick with regular unleaded to save money.

Using premium fuel can actually harm your engine if your car is not designed for it. Stick with regular unleaded to avoid potentially costly damages.
