Hi All,
I'm not a Chemist, but I thought the level of pollutants produced by
Unleaded fuel was considered more dangerous than those produced by
leaded, because of the high level of carcinogenic aromatics necessary to
raise the Octane to the same level as leaded. The only advantage of the
unleaded is the ability it gives to use a catalytic converter, which
once warm, Genuinely gives a reduction in pollutants.
Comments from any Chemists on the list would be welcome.
Bill.
