Interesting theory. Less emissions=lower mpg. Lower mpg=more fuel. More fuel=more emissions. Wow they thought that one through

 

I wonder if you can add sulfer back to the fuel with some additive?

 

I guess this doesn't sound all that bad to me. The Chevron info said it was only on the order of 1% reduction in BTU's. That's not very much. It also said that the process to remove the sulfur also removed some of the aromatics (garbage) in fuel, resulting in a higher cetane number. That's not bad at all.

 

so far it loks like ill loose about 1.5 mpg on it... to soon to get hard #'s but its looking like about 7% reduction overall..

 

Sulfur has no use in the fuel, it's the process of sulfur removal that strips the lube out of the fuel.They just want the sulfur out so the new pollution devices don't clog up on the newer trucks coming, and the new pollution devices are what drop the mileage on the trucks, not the lack of sulfur. If the refiners put enough lube back in the fuel after the sulfur removal process is the big question, I'll just keep using my additive for now.

 

You pretty much got it right and the drop in MPG some people are seeing could be due to winter fuel coming on line at the same time frame as ULSD.

 

I got our dealer (motorcycle) gas tank filled yesterday and I asked the driver about ULS and was told by him all the fuel being delivered is now ultra low sulfur even if the pumps don't state it. He said the low sulfur is being colored for off road use only. This is in Florida, don't know about other states.

 

Does anybody know if there is a possible reason why Fuel Pressure would increase some by using the ULSD?

My fuel pressure has increased about 1.5-2 psi to about 9psi at idle now. I am still on my stock lift pump. No other changes that I can think of that would cause an "increase".

I did just change my fuel filter today, but it didn't really seem to make any difference. My FP has been reading higher for about the past 3 weeks to a month or so. Not complaining...just curious.

 

I have a family member who delivers fuel, he tells me that the lub is added automaticly by a computer when he fills the tanker with Diesel. So what ever the computer adds is what we get.

I just hope the computer is not run by Windows 98, 98 SE, ME, 2000, XP or anything else made by Microsoft (Blue Screen of Death = Ctrl, Alt, Delete = restart) who knows what we may get mixed in with our diesel fuel.

If ULSD has only 1% less BTU output then why do I lose 2.5 mpg now that it is here and has been for a while? BTW it's not due to winter blend that is not here yet.

 

More on this subject:

"A deadline affecting how diesel fuel is mixed is looming and may cost users a lot of money in fines.

Don Francis, certified energy specialist with Cenex, said the 1990 Clean Air Act establishes certain diesel criteria affecting the use of sulfur that must be in place by June 1, 2007. By that time, diesel for off-road use in service stations or by dealers must have a sulfur content down to 500 parts per million. Onroad diesel fuel must be ultra-low sulfur — down to 15 parts per million by Oct. 15 at retail levels."

"When the sulfur content of diesel is lowered, he said, the product becomes very dry and has less lubricating ability. Refineries have to add lubricants and detergents to the fuel to prevent engine problems, such as plugged up injectors, he said.

Using ultra-low sulfur diesel has been in effect in Europe for a number of years, he said, and scientists have learned a little about it because of that.

Francis warned using lower than premium brand diesel may damage an engine. He said No. 2 diesel may not have a fuel additive package and urged diesel-users to stay with major brands.

“A lot of people don’t know about this and it is creeping up on them,” he said."

I don't mean to hop off topic here but I have a quick question to ask.

At my local Shell station they have 2 choices for diesel, regular ol #2 and a Premium option, what's they difference between the two?

 

Cetane rating? I hope it's not two pumps but only one tank.


On average, what's the price difference?

 

No ULSD here in the twin cities, at least at the stations I frequent. I think we are running wblended fuel though. I thought it was October 1st but it may be the 15th.

 

ShaneCTD600,

Our fuel comes out of the pipline from the Twin Cities, we are the first tank farm on the line going south in IA. So I would think that you have it up their, but maybe the station you buy from is still selling normal LSD.

Several places here have yet to update there pumps to show ULSD. I think it is a CYA by not changeing it over until 1/01/07

My $0.02
