All the fuel available now is ultra low sulfur diesel (ULSD) which has fewer than 15ppm sulfur in it, it replaced low sulfur diesel (LSD) what had fewer than 500ppm of sulfur in it. While the decrease of sulfur makes it "less polluting" it also makes it MUCH LESS lubricating. This can cause premature failure of fuel system components such as the CP3 pump and injectors...to replace both would cost in the neighborhood of 6k including labor. Trucks made before 2007 are the most susceptible to these failures as their parts were not designed with the lower sulfur content in mind.

NOW, fuel companies are required to replace the lost lubricity with additives to prevent these failures. It has been seen through testing that this is not always the case. Cheap insurance is to use a diesel additive when refueling. This will ensure that the proper lubricity is present and will keep your engine happy.

Most guys run either standadyne or power service diesel kleen as it is cheap and readily available. Some also run 50/50 additive/2 cycle oil. I run the 50/50 mix as i also have a high mileage engine and would like to keep it going strong.

I just bought a 80oz bottle of power service diesel kleen (grey bottle) for 20 bucks at walmart, their 2 cycle oil is really cheap too...even if you run the straight 8oz of diesel kleen thats 10 tanks of fuel, or 2 bucks a tank...well worth the extra cash in the long run.


Below is a study done on the various available additives.

DIESEL FUEL LUBRICITY ADDITIVES

DIESEL FUEL LUBRICITY ADDITIVES STUDY RESULTS
METHOD:
An independent research firm was hired to do the laboratory work. The cost
of the research was paid for voluntarily by the participating additive
manufacturers. Declining to participate and pay for the research were the
following companies: Amsoil and Power Service. Because these are popular
products it was determined that they needed to be included in the study.
These products were tested using funds collected by diesel enthusiasts at
“dieselplace.com”. Additionally, unconventional additives such as 2-cycle oil
and used motor oil were tested for their abilities to aid in diesel fuel lubricity.
These were also paid for by members of “dieselplace.com”.
The study was conducted in the following manner:
-The independent research firm obtained a quantity of “untreated” ULSD fuel
from a supplier. This fuel was basic ULSD fuel intended for use in diesel
engines. However, this sample was acquired PRIOR to any attempt to
additize the fuel for the purpose of replacing lost lubricity. In other words, it
was a “worst case scenario, very dry diesel fuel” that would likely cause
damage to any fuel delivery system. The fuel was tested using the HFRR
testing facility at the Laboratory. This fuel was determined to have a
very high HFRR score of 636 microns, typical of an untreated ULSD
fuel. It was determined that this batch of fuel would be utilized as the
baseline fuel for testing all of the additives. The baseline fuel HFRR score of
636 would be used as the control sample. All additives tested would be
evaluated on their ability to replace lost lubricity to the fuel by comparing
their scores to the control sample. Any score under 636 shows improvement
to the fuels ability to lubricate the fuel delivery system of a diesel engine.
BLIND STUDY:
In order to ensure a completely unbiased approach to the study, the
following steps were taken:
Each additive tested was obtained independently via internet or over the
counter purchases. The only exceptions were Opti-Lube XPD and the biodiesel
sample. The reason for this is because Opti-Lube XPD additive was
considered “experimental” at the time of test enrollment and was not yet on
the market. It was sent directly from Opti-Lube company. The bio-diesel
sample was sponsored by Renewable Energy Group. One of their suppliers,
E.H. Wolf and Sons in Slinger, Wisconsin supplied us with a sample of 100%
Copyright© The Diesel Place & A. D. Spicer - 4 - August, 2007
soybean based bio-diesel. This sample was used to blend with the baseline
fuel to create a 2% bio-diesel for testing.
Each additive was bottled separately in identical glass containers. The
bottles were labeled only with a number. This number corresponded to the
additive contained in the bottle. The order of numbering was done randomly
by drawing names out of a hat. Only Spicer Research held the key to the
additives in each bottle.
The additive samples were then sent in a box to the independent research
firm for testing. The only information given them was the ratio of fuel to be
added to each additive sample. For example, bottle “A” needs to be mixed at
a ratio of “480-1”. The ratio used for each additive was the “prescribed
dosage” found on the bottle label for that product. Used motor oil and 2-
cycle oil were tested at a rationally chosen ratio of 200:1.
The technician at the laboratory mixed the proper ratio of each “bottled
fluid” into a separate container containing the baseline fuel. The data,
therefore, is meaningful because every additive is tested in the same way
using the same fuel. A side-by-side comparison of the effectiveness of each
additive is now obtainable.
THE RESULTS:
These results are listed in the order of performance in the HFRR test. The
baseline fuel used in every test started at an HFRR score of 636. The
score shown is the tested HFRR score of the baseline fuel/additive blend.
Also included is the wear scar improvement provided by the additive as well
as other claimed benefits of the additive. Each additive is also categorized as
a Multi-purpose additive, Multi-purpose + anti-gel, Lubricity only, nonconventional,
or as an additive capable of treating both gasoline and diesel
fuel.
As a convenience to the reader there is also information on price per treated
tank of diesel fuel (using a 26 gallon tank), and dosage per 26 gallon tank
provided as “ounces of additive per 26 gallon tank”.

CONCLUSIONS:
Products 1 through 4 were able to improve the unadditized fuel to an
HFRR score of 460 or better. This meets the strictest requirements
requested by the Engine Manufacturers Association.
Products 1 through 9 were able to improve the unadditized fuel to an
HFRR score of 520 or better, meeting the U.S. diesel fuel requirements for
maximum wear scar in a commercially available diesel fuel.
Copyright© The Diesel Place & A. D. Spicer - 9 - August, 2007
Products 16 through 19 were found to cause the fuel/additive blend to
perform worse than the baseline fuel. The cause for this is speculative. This
is not unprecedented in HFRR testing and can be caused by alcohol or other
components in the additives. Further investigation into the possibilities
behind these poor results will be investigated.
Any additive testing within +/- 20 microns of the baseline fuel could be
considered to have no significant change. The repeatability of this test allows for a
+/- 20 micron variability to be considered insignificant.
CREDITS:
This study would not have been possible without the participation of all
companies involved, the independent research firm, and dieselplace.com. A
special Thank You to all of the dieselplace.com members who generously
donated toward this study and waited longer than they should have for the
results.
You folks are the best.

goin broke but N style

pretty good info. i personally dont own a diesel, but know several that do. Only 1 is a 07 model the rest are mid to late 90's models.

I have seen major issues with this fuel working on the older 90's Mercedes diesels. we are constantly repalcing fuel lines due to dry rot. Every service we ADD the BG diesel fuel additive, that is supposed to add lubricity to the fuel.

I have heard of running ash-less synthetic 2cyl oil. i have never done it, but a few have.

Would these additives affect the pdf filters in the exhaust of these diesel's?

I'm glad to see Amsoil on there even though they didn't participate directly. Very good write up.

they will normally say if they are ok for vehicles with dpf's, most are compliant i think, i do know that the 2 stroke oil is not to be used on dpf trucks.

thats what i tought. I have just read on other forums that they add it to the fuel. Now i have no idea wether they still have the pdf's or not.

some of these additives i have heard of and some i have not, but not owning a diesel, i am not surprised.

I would assume all/most of these are over the counter additives?

actually most are order only...there are some available at the parts stores, diesel kleen is by far the most available.
