Forgot to say! Supermarket fuel is cheap because it doesn't have the additives the premium fuels have, part of which are cleaners!
Like regular oil changes are the cheapest repair you can carry out, so too is fuel quality. just use the 98 RON premium fuels which burn cleaner and have all additives to clean and lubricate the fuel/combustion areas of the engine. You will get more miles to the gallon and more smiles to the mile as well! When you look at cost per mile it will be almost non existent!
