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.

 

Didnt someone post on this site from a Cummins rep that the ULSD has the same BTU per gallon as the LSD? My mileage has not decreased. Still hovering around 20-21.

 

I think it has made its way here. My last 2 tank fills were lower by 2-3 mpg also.

 

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.

 

Thats ridiculous, we still have the old smokey diesel here, guess we need to get our kicks in on it now before things get worse!!!! ;.; Bye bye smoke.

i dont think i have run it yet but my brother has seen it around our area. and i hate the fact that there are 70 cents difference between gas and diesel. maybe i have ran it, i was wondering y i was loosing some economy....hhhmmmmm im gonna have to check into that.

 

are you trying to start another rant on the welfare system?

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.

 

Saw a difference of 88cents in Denton TX!!!!!

 

Not at all, but you know as well as I that if someone who can't afford it gets sick in this country they aren't denied treatment. All of us end up paying for sickness in the long run.

 

how correct you are.

 

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.

 

"...if someone who can't afford it gets sick in this country they aren't denied treatment."

That depends on what insurance company is involved.
