I have heard that the new EPA limits on particulate emmision standards on over-the-road diesels have forced manufacturers to equip new diesel vehicles with equipment that increase fuel consumption by x2. Can anyone site proof of this, or is this a rumor? Key phrase: site proof. Include sources please.
Perhaps I’m in the wrong place. I’m looking for proof one way or the other, not hearsay. It’s easy to cut mileage in half, especially if you have a scrubber on your exhaust that effectively clogs it. I’m not saying that it’s what is happening, but I have heard of truckers and diesel truck buyers complaining, so I’m looking for verification if anyone has it.
FYI, I’m not debating the exsistance of global warming right now. It was mainly a ploy to get you to read this. My main concern in asking this is fuel economy.
