Will this affect pre-2006 diesel models? Thanks.

 

I would think that it would be very difficult to expect older vehicles still on the road to conform to the new higher standard clean-air specifications as brand new vehicles.
They don't do it with gassers.

 

Mesdagh - not sure what you're talking about. If you're speaking of the country's conversion in 2006 to ultra low sulfur diesel - that's a change in fuel quality that will not affect pre 2006 vehicles - aside from possibly needing a lubricity additive.

I'm not aware of new vehicle emissions standards, but as always, older models are grandfathered in those cases.

 

Good news about the grandfathering...

I thought I heard there was a change in emissions standards also. I did a bit of searching and it looks like there will be a new diesel emissions standard in 2007 ... but it looks like it's only for heavy duty engines and buses. So I think we are safe.

 

Don't quote me on the grandfathering, but that's how it's been traditionally. They can't expect folks to spend money to convert older vehicles to new standards.

 

with the new ultra low sulfur diesel, all diesel trucks will have lower emissions.
of course we will need to add a lubricity additive.
b-5 would work (5% bio-diesel), lucas or other additive's.
most of the auto makers are making diesel cars and trucks that can't meet our emissions standards now, are being sold in other country's, these same cars and trucks will pass emissions with uls fuel.

 

That's because politicians don't like being lynched.

Will the PS diesel additive (white bottle) add enough lubricity to offset the loss of sulfur.

First of all the fuel producers will be required to add a lubricity enhancer to all ULSD to compensate for this problem. So as it is now, it will likely run just fine with no additives in our vehicles. However, there are some folks that like the insurance of putting them in themselves, myself being one of them. I have a case sitting around of stanadyne lubricity formula - which contains 4x the lubricity of their performance formula, and none of the other elements. Since I don't agree with Stanadyne's method of demulsification, I will continue to use my redline additives, with a shot of the lubricity formula or biodiesel. I prefer the bio route.

 

The "older" p7100 pumps need 5% sulfur minimum, not sure about the older VP's or the new ones. Most don't know it, but alot of areas, including mine are only at 3%....even the heavy stuff. I spike my fuel with lucas and can hear the difference in the pump.

I didn't think sulphur was the lubricating agent in diesel fuel????

I'd rather run bio(soy) anyway

What about just dumping in some motor oil? Two cycle oil?

 

The refining process that removes sulfur for LSD and ULSD simultaneously strips the fuel's lubricity as a side effect of the process. Sulfur is not the lubricant, but as you can expect from what I just stated, high sulfur fuel has much higher lubricity..

 

Your decimal points are a bit off
Current on-road diesel is low sulfur fuel at 500 ppmw or 0.05%
Where?
I talked to a major midwest refinery rep 2 weeks ago about ULSF. They have no requirement to add lubricity.
What you write is partially true. Sulfur bearing emissions are lower. ULSF itself does not lower NOx or Hydrocarbon (HC) emissions. It slightly reduces Particulate Matter (PM) emissions.

The big reduction is gained by adding a PM scrubber or diesel particulate filter (DPF). That will be retroactive on many school and transit buses.

 

There is a lot of talk going around about lubricity standards and I've read and heard from a few industry experts that it's likely to be imposed as a requirement. I shoudn't have said that it was as a definite. In any case, requirement or not, most ULSD manufacturers are additizing ULSD to compensate for the lost lubricity.

 

LOL
I was just replying to you in the "burning oil?" thread.
The guy at Koch refinery said they know the fuel will be very dry after the de-sulfuring process, but haven't decided to add lubricity. Here in Minnesota, the lubricity issue will be a non issue. By July, all diesel will have 2% bio.
