I've noticed a big difference since the recent introduction of the Ultra
Low Sulfur (15 ppm) fuel in this area of the county. With the older fuel
(Low Sulfur - 500 ppm), my F-350 would occasionally give up a whiff of
diesel exhaust, especially when cold, and the tailpipe tip would be
pretty much soot covered between washings.

The new ULS fuel yields absolutely no diesel exhaust smell at all ... and
I noticed yesterday that although the truck had not been washed in
several weeks, the exhaust tip was still relatively clean.

I think ... (not exactly sure) that the 15 ppm fuel will be required for
marine engines in 2008 or 2010. I am convinced it will reduce transom
washing much more than any magical magnetic device.

Have you noticed any appreciable performance issues with the new fuel?


I have not, other than the lack of any diesel smell upon start-up and no
smoke when cold. The engine seems to run smoother, but that might be my
imagination.

Some people are reporting a slight decrease in MPG, but I haven't noticed
it. I've been using it since October.

Winter blend diesel fuel gets slightly less MPG than the summer blend
anyway.
