Where are you at? I haven't seen leaded gas or petrol since I was in grade school. They used to call it "regular" and there was that and diesel until they decided the lead in gasoline was bad for us and started offering unleaded. Eventually, every gas station in the U.S. phased regular gas out. If you have an old car from the days of leaded petrol, you'll probably have to put unleaded in it some time (unless you live in a country where they still have leaded gas at the stations). If you put unleaded gas in an old car, you can get a fuel additive to protect the engine from the harsher fuel. Over time, using unleaded in an old engine can cause some of the gaskets to dry out and start leaking. It won't hurt just one time, but it's an accumulative effect if you do it all the time.
