We’ve all seen those pricier fuel pumps next to the regular unleaded and diesel nozzles named something along the lines of Premium, Momentum or Super, but what is premium fuel and should you be buying it?

Octane is a chemical component of petrol, and the amount found in a fuel determines how well it works in higher compression engines, such as performance cars.
