[quote davester]My understanding is that diesels are not legal in California (and elsewhere in the US?) because US diesel fuel standards are very lax compared to european standards, which results in high sulfur emissions from US diesel. I seem to recall that US standards are supposed to improve, so that we could once again purchase diesel cars. Does anyone know if this is true?
As with gasoline Calif and Ma. emmisions requirements are extremely tight. Diesels don't meet the requirements.
U.S. requirements are actually tighter than European, why they have dirty diesels and we don't.
Engine manufacturers are working on the emmisions, and fuel suppliers are working on lower sulfer content fuel.
European countries are working on emmisions to clean up the air and also the disparity in fuel prices between countries.
We'll have diesels again.
