I think there's a point being missed here,
Unless a Catalytic Converter is fitted to a vehicle, Unleaded fuel is
proven to be MORE dangerous than Leaded.
If a Catalytic Converter is fitted but driven cold, Sulphur Dioxide is
produced.
When Catalytic Converters break down, they deposit Platinum into the
atmosphere.
I'll state again that I'm not a Chemist, and if anyone is qualified to
tell me I'm wrong, I'll happily accept that.
