Why is it called unleaded and super unleaded? Lead isnt in petrol naturally (might be wrong on this but didnt think lead was in oil) and only started to be added in the US in the 1920's to reduce engine knock.
So therefore they havent removed any lead, why not just call it petrol? this is what is it? They could have called it uncoloured petrol or anything.
