Hi,
Recently bought a 2.25 petrol SIII, when I asked the guy I bought it from about using unleaded he said he added an STP " complete Fuel System Cleaner" for petrol engines. He told me to add 250mls to the tank after every 3 or 4 fills. The instructions on the bottle says to add 500ml to a full tank every 4000 miles. Does anyone have an opinion on this or a suggestion for using unleaded / engine cleaners?
