DPF - only reason for ULSD?

Is the DPF the only reason we have to run Ultra Low Sulfar Diesel in our trucks?

Pretty much, yes. However, in 2010, its going to be the only diesel available throughout the US & Canada, so don't sweat the load.

How Can That Be The Only Diesel Available? Theres No Way The Construction And Farm Industries Will Go For The Elimination Of Red Fuel, Unless You Meant That Will Be The Only Diesel Available For On-road Use.

It's already very rare to find ANY high sulfur diesel left in the US. Low sulfur is now a rarity, and in 2010 ALL diesel fuel will be mandated by Federal law to be ULSD.

"Red fuel" has not been high sulfur for several years now. Its just a dye added for tax purposes. Most refineries are already converted to ULSD & not making LSD. Its just too costly to make 2 different fuels.

Our off road diesel is ULSD [Red] Boss orders it that way from our fuel supplier. That way all our engines run on the same fuel.

Wow, Maybe Florida Is Just Behind The Learning Curve, There Is 4 Fuel Stations Within Fove Miles Of My House Where You Can Get High Sulfer Red Fuel, And It Even Says On The Pump 500ppm Of Sulfur Or More. Those Same Stations Do Carry Ulsd For On-road Vehicles Also. And One Maybe 2 Fuel Stations In My Area Still Have Low Sulfur, But Im Sure They Will Soon Go To Ulsd. I Guess They Will Be Running Ulsd Red Fuel Down Here Soon Too. Its Just Rediculous Though, My Fuel Mileage Took A Dive Off The Deep End When They Made That Garbage!

I buy the red diesel for my tractor and the sticker on the pump says high sulphur diesel but the guy in the tanker truck says it's ULSD with red dye. The station owner never bothered to peal of the sticker.

i dont get it they made ULSD to help our enviornment but inturn were actally not helping it at all because with the ULSD you drop from like 14mpg to 8 (just random numbers) which is useing more fuel which is putting the same amount of sulfer into the air and eliminating our crude oil supply and jacking up the diesel price

where in there is helping our enviornment or our economy?

And that's the $64,000 question! How the heck is burning more fuel with less smoke better??? It can't be answered and it's like when they added MTBE or what ever that additive was to gasoline.

I don't get the MPG drop of ULSD. I had 3 trucks, one 7.3 and two 6.0's and the MPG stayed the same before and after ULSD roll out. I do see MPG loss in winter but that was there in the LSD days too, winter fuel with less cetane the likely culprit there. Maybe a little warm up running to get a warm heater also to blame.
my biggest MPG problem is my right foot and not ignoring trucks passing me when I'm trying to be frugal.

Interesting comment about the drop in economy. with ULSD I only see 1-2MPG drop to my 6.4 from my 7.3 when both used ULSD.

What is even more troubling about ULSD is that it makes a large portion of the oil that is high in sulpher not easily refined for this new fuel spec. Much of this is Mid-East oil which now doesn't work so well. Less raw supply which means prices go up.

Don't kid yourself, friend. The reason diesel went up is so that we can bear the cost of the refineries re-tooling to produce ULSD. They are still making record profits- so I guess the raping diesel consumers take at the pumps hasn't covered their costs yet. It probably never will as long as consumers are forced to pay it.

Hey friend, this just in, the U.S. does not have meaningful influence on the price at the pump. While the change in ULSD at the refinery has added cost (same for the ridiculous amount of boutique gas blends) it is not the main factor. Price per barrel is. Price per barrel is influenced by OPEC which has 2/3 of the reserves. Our diving monetary policy has driven the price up as well. The Saudis laughed at Bush when he asked for an increase in production.

Let's pick on Exxon, the worlds largest public oil company. IIRC, they are 14th on the list of oil reserves. 14th and they control less than 4% of the worlds production. They have little bite on the subject. They are making record profits because they are selling more unit volume at a higher price. I assume the same would happen in your business. We can apply windfall tax but who determines that and how much? In any event, it's doubtful the tax would lower prices at the pump.

We can cut usage which will then be consumed elsewhere in the world. Plenty of oil but demand is rising and it is going to cost more to explore and produce.

Not trying to be argumentative here, but diesel has been historically lower in price than gasoline, or at least close to the same. Seems strange to me that with the onset of ULSD production, the per-gallon cost sailed past that of gasoline, and is currently almost 25% more now. Coincidence?

A windfall tax would be a disaster, that cost would only be passed on to us as well. Someone needs to figure out a way to squeeze both OPEC and the refineries in such a way that they can't simply retaliate by raising prices, although that is unlikely the way the market is structured. For now, we're just screwed.
