In a general way what are less pollutant? Diesel or Gasoline motors? Trends for the near future oil combustibles will be related with this question. Recent inquiries have pointed the fact of MTBE to contain cancerous properties and to be responsible for the contamination of water ponds. Is this true or we are dealing with an ecological fundamentalism? Can we question that there are commercial lobbies behind these statements? Ethanol Gasoline? ELS Diesels? How do we achieve extra low sulphur 10 p.p.m diesels in a sustainable way? These are reflection matters that I place for the forum discussion.
