Everyone seems bent on the emissions that diesels are emitting... Biodiesel has NO harmful emissions and within the next 2-3 years will be available everywhere normal diesel is sold and will be plentiful to the point it will be cheaper than normal diesel. Granted not all diesels will be able to run on more than a 5% biodiesel blend without modification, but that will change. Chrysler alone is certifying their Jeep CRD to run on B20 (20% biodiesel). So, is there complete justification for the negative view on the upcoming diesels?
