This link (http://www.delphidiesel.com/DATA/DDSU203.pdf) shows the Power Servise Additive(DK) as worse than un treated diesel fuel. I have bee using DK for years and my brothers use Stanadyne But my one brother switched to Delphi on the recomendation of his mechanig at Gilette Diesel. Whats up with that?

 

obviously an inhouse test.

 

Instead of asking us... as Diesel Kleen (Power Service).

Send them an email from their website along with the link you have above and ask for their comments and how or why does their report show what it does?

You at least owe it to them to respond in a business appropiate manner and within a week to your email.

Let me know... I use Powerservice with great results... so far??

 

I sent them the link and asked for an explination on friday the 24th. Still waiting for a reply. I'll let you know!

 

I got a reply from Power Service.

Dear Machinistika:

<o></o>

Thanks for bringing this to our attention.

<o></o>

No, our current Diesel Kleen + Cetane Boost or Diesel Fuel Supplement<o></o>

would NOT make lubricity worse in any test or fuel.<o></o>

<o></o>

Attached are some HFRR data (D6079 High Frequency Reciprocating Rig) in<o></o>

ULSD's done over the last 6-8 months on DK+CB. Fuels vary around the<o></o>
country, and some are more "treatable" than others. Even so, our<o></o>

products significantly improve lubricity in ULSD's, which is all that<o></o>

matters today. Most of the fuels we test are unadditized, and as shown<o></o>

attached, many of them do not meet the current D975 lubricity<o></o>

specification.<o></o>

<o></o>

Consider the following about the <st1>lace w:st="on">Delphi</st1>lace> posting:<o></o>

<o></o>

1. Copyright is 2004, so the data is at least 2+ years old. The data has<o></o>

to be in a non-ULSD fuel, and could be as much as 3+ years old. See the<o></o>

file name that ends in 203 (Feb of 03)?<o></o><o></o>2. The product name is "power service new formula with lubricity<o></o>

improver" and the treat rate is 1:500, neither of which is recognizable<o></o>>

to me over the last 3+ years. In 2004, our Diesel Kleen + Cetane Boost<o></o>and Diesel Fuel Supplement were improved in lubricity properties by the<o></o>

addition of Slick Diesel, a proprietary mixture of lubricity agents. <o></o>

<o></o>

3. The test is a SCBOCLE, which is a different test measurement device<o></o>

than the HFRR, which we use exclusively and was finally use to establish<o></o>

the current D975 lubricity specification effective January, 2005. The<o></o>

SCBOCLE is a "research tool" that was standardized, but never accepted<o></o>

for the standard, even as an option.<o></o>

<o></o>

Thank you for your interest in our products. Continued use of DK year<o></o>

round and DFS in the winter will protect your diesel fueled equipment<o></o>

from pre-mature wear due to poor lubricity fuels.<o></o>

<o></o>

Best regards,<o></o>

<o></o>

David Forester<o></o>

Director of Technical Services<o></o> <o></o>

 

See... email and you will receive....

I am sold on PowerServices answer and they obviously read and researched every aspect of the information you sent them... down to looking at the date of the material and the research file name.

Scary to think that much, or some, of the diesel out there does not meet the ASTM standard... but then again this is why I use a fuel additive in every tank fill-up with out fail!!!!

 

Good job guys! Locating and providing data and killing rumor.
