From what I know when diesel fumes exits the exhaust they fall to the ground where gas fume go into the atmosphere.

the US was once 1 of the biggest polluters for automobiles, now, the US is 1 of the cleanest for emmisions as far as auto's go. our emmisions standards are far tighter than any other nation. Europe's emissions standards are fairly loose.35WINDOW said:Diesels are big in Europe-I wonder, are they that far ahead of us in Diesel Technology, or are they using them for fuel economy (or both)?
Taxes and dye is the only difference as far as I know. They add dye to the off road fuel so it can be easily checked. There is a big fine for using the off road diesel on the road. I have a friend that loves to buy diesel cars and burn off road diesel in them since he has never heard of the authorities checking a car's fuel. As far as he knows they only check pickups and trucks.farna said:The biggest reason for "off road use only" is the TAXES charged for road use, not sulfur content. I'm not saying that the off road fuel isn't higher sulfur (though I doubt it -- would it pay to refine two different types? Might, but...), but the diesel for farm use is cheaper because the road taxes aren't applied.
