diesel additives experts

Well I have just used my last drop of Diesel Kleen. My supplier has either gone belly up or fallen of the face of the earth cause I cant find anyone over here that stocks it. Now I dont want to throw anything into my tank and I have been contacted by a ProMa supplier selling DT5. Can some have a look at the PDF and shed some advice.

Do you have a fuel issue in Australia that you are trying to solve?

Not really. I believe our sulphur content is lower than u guys. The only issue I see over here is water. I go through about 1000ltrs per week between my F truck and my work truck. I was impressed with DK with the fuel economy and the way it silenced my injectors. Proma is boasting increased fuel economy and HP.

That doesn't tell much. If you are worried about lubricity, you need to check the fuel lubricity. ULSD here is 15ppm of sulfur. They are mandated to add lubricants to bring it to a HFFR score of 520. So, without knowing what your fuel is rated at, it is very difficult to say what you need.

Have you tried a water filter in line? I have a water separator in my fuel line.

People usually are impressed when they hear the injectors being silenced. I would be if they could actually tell that it is being quiet without sophisticated sound filtering equipment. Injectors buzz. I can't hear them over the combustion noise the engine makes. What I think you are hearing is the combustion noise changing. Not sure exactly what it means either way. Biodiesel makes it quieter too. Too bad it has less BTU when compared with regular diesel. ULSD also has slightly lowered BTU, at least here. Not sure about your fuel situation there.

From what I have read, a additive with a lowest HFRR score lubricates the best. Is that right ?? If so I will get him to supply me with its HFRR score.

Yes, that is correct. HOWEVER, there is a point of diminishing returns. If you are hungry, a plate of food is good. 5 plates might not be so good.

http://www.arb.ca.gov/fuels/gasoline...22003bosch.pdf

Look at page 10 and you can see that by going with the US recommended 520 instead of manufacturer desired 460, you increase your assessed rating by 1, give or take. Look at the next page. You see that an increase of 1 probably gets no more than 10% loss. After all, just because you cross the line from 3.5 doesn't automatically mean a 20% loss and if you are 3.4, you are totally good. Figure it at say no more than 10%.

If your injector rebuild costs say $2000, I think it is fair to say that it is costing you about 10% of the rebuild. 10% of $2000 is $200. This means that to pay for itself, if your injectors typically last 200K, you cannot spend more than $200 to break even. So, the question is whether you think it is economical to save $200 by spending say $500. IF your goal is to squeeze the max life out of the injectors, damn the cost, sure.

According to the following link, Stanadyne fairs better than DK if you are looking at the HFRR #'s..

Brain, is Stanadyne available in Australia ?

But without knowing what his fuel is rated at, what would the point be? All that tells you is what gives more lubricity. Without knowing his starting point, all that Spicer alludes to is "More is better". If he has fuel at 400 HFFR, what more can he do even if he uses Biodiesel? Without knowing what he has, how does he calculate what he needs and the point of diminishing returns?

Most of my info gathering came from here
Bushtracker Forum :: View topic - ULTRA LOW SULFUR DIESEL LUBRICITY AGENTS AND ADDED LUBE
They say that they add lubricity agent, but dont specify how much. From what I have read the sulphur content is 11PPM.
The best Proma could offer me regarding HFFR was this study
http://fueloiltreatments.com.au/Pdfs/testingresults.pdf
If the 10% fuel economy saving is true Im looking at 100ltrs @ $1.22 per litre saving per week.

IIRC, it is the process of removing sulfur that lowers the lubricity and not the sulfur itself. Besides, 11 to 15 isn't that much of a difference so I am not sure if the process strips off that much lubricity. Without knowing what the AU govt mandates, it is impossible to even guess what you have and thus what you need.

The 2nd link seems to be for gas engines. I scanned it for "diesel", "lubricity" and "HFFR" but got nothing.

Tricky. Found it. It won't fix your lubricity issues unless you know what it is. Not sure exactly. Test results look good but IF it could, save 10%, it might be something to look into. Somehow I doubt that you will get as good a result as the test but hard to say. I did notice that you have better cetane than we do. I don't think we can get 52 here easily
