\nCatalysed petrol<\/strong> is the unleaded petrol used by vehicles fitted with a catalytic converter. It is not a special type of fuel: it is the 95 or 98 petrol sold today at any filling station, formulated without lead so as not to damage the precious metals (platinum, palladium and rhodium) in the catalytic converter. It has been mandatory in Spain for all petrol cars since 1993 and for diesel cars since 1997. Its purpose is to reduce polluting emissions and protect the engine.<\/div>\n

It is one of the most common questions among drivers: they hear about “catalysed petrol” and think it is a different fuel from the one they usually buy. The reality is simpler: all petrol sold in Spain today is catalysed. You don’t need to ask for it specially or look for a particular pump. Any unleaded 95 or 98 petrol is suitable for cars with a catalytic converter.<\/p>\n

In this article we explain, from our experience as a filling station, exactly what catalysed petrol is, how it differs from the petrol used in the past, how a car’s catalytic converter works, what it means for vehicle maintenance and what to bear in mind if you drive a classic car built before the 1990s.<\/p>\n
