Most drivers choose petrol by price, habit or whichever forecourt is closest. But not all petrol is marketed with the same additive packages, detergents or premium options — and the fuel you use can matter for injector cleanliness, carbon build-up and long-term engine care.

In this video, we compare five major UK petrol brands and look at what you are actually putting in your tank. Is premium unleaded worth the extra money? Is supermarket petrol really worse? And when does it make sense to change where you fill up?

We break down the claims, the differences between standard and premium petrol, E10 fuel, detergent additives and the mistakes that can cost drivers money over time.

Always use the fuel grade recommended in your car’s handbook.

Which petrol station do you use — and have you ever noticed a difference in how your car runs? Let us know in the comments.
