So whats with this new low sulfur diesel and the label saying "Not for use in 2007 vehicles and later"? So in other words if you buy a 2007 diesel you can't buy fuel for it anywhere??? This stuff is junk though, last week I averaged only 10mpg! I'm normally up near 19-20mpg, and I even added my fuel additive as I've read you should with this new crap. Just another way to keep the people down.
