It seems Diesel & Gasser alike have a new cross to bear. 
and it's called EPA Clean Air Regs.
The tests with gassers running E85 Ethanol/Gasoline show a reduction of ~25% in mpg over straight gasoline.
At least we're still looking at better efficiency.

What gripes me is they are useing it as a excuse,to keep diesel prices high. If gas drops much more around here,there is going to be a dollar a gallon differance,between gas and diesel,it's at 77 cents now.

Energy Content:
In general, the processing required to reduce sulfur to 15 ppm also reduces the aromatics content and density of diesel fuel, resulting in a reduction in energy content (BTU/gal). The expected reduction in energy content is on the order of 1% and may affect fuel mileage.

ulsd isnt here yet, the mileage is bad enough. not much I can do there, just wondering what it is actually going to do to my performance though.

Diesel has been averaging about 40 cents a gallon more than regular here in Houston. I did see it for 2.749 at a Shell station on my way to work this morning. I find it hard to believe is costs the refiners ~.50/gallon more to make ULSD than it did to make LSD. Are they trying to recoup ALL of their investment on their new refining equipment immediately? Are diesel drivers now subsidizing the gasoline drivers? I see no reason for diesel to be so much higher than gas. Even ULSD in not as refined a product as regular unleaded.

Noticed yesterday that the local station had changed the sticker to say that 2007 and newer CAN run this fuel.
Only ran ~120 miles so far, and the overhead is reading 15.2 (remodeling my bathroom, and like any plumbing job, it takes 5 trips to Home Depot to get everything, so there were 4 or 5 trips of 6 miles roundtrip in there to kill the mileage).
With the trip I made yesterday, plus a bunch of small trips, I would normally still read 16.1 - 16.4 on the overhead (which normally runs 16.5-17.0 hand calc'd).
I realize 1/4 tank isn't very revealing, but so far it seems as though it has dropped a bit...and if you figure that I still had about 5 gal of LSD in the tank, it does not bode well for the ULSD. Guess I'll get a better feel after a few tanks...I'll just tell the wife that I have to make a bunch of trips for "research!".
BTW...the station with the ULSD dropped almost 30 cents in the week since I last filled up, and that was when they were still running LSD. Now they are about 10 cents cheaper than the Exxon a mile away that still has LSD. Go figure.

I've actually gotten better efficiencies with ULSD. I got an average of 21 in Texas this summer with it (city highway) and got about 18 with B99. In New Mexico I found some and got 24 mpg. With the LSD here in Oklahoma I get about 19 mpg.
I remember hearing somewhere that the ULSD is supposed to have a higher cetane number, but I could just be delirious.
