Welcome to the forum. There are plenty of threads on here if you use the search function, that way you can get your answers quicker than waiting on everyone to chime in.

However I use standadyne, and when i run out of that diesel kleen, both mixed with 2 stroke.

Welcome to DF. Same as nvrplzd, Stanadyne is first choice, DK is #2. I just bought a case of Stanadyne so should be good for a while. I haven't tried 2 stroke oil mix yet, sounds like it should work though.

^Ive always heard nasty things about using sea foam in diesels.. something about the alcohol it contains doing the opposite of lubrication and hurting way more than helping in the long run.. just be careful with that one..

You can always look at actual test results....then make a decision

The following are the preliminary results of a research study on diesel fuel
Lubricity Additives. There is likely to be further commentary and explanation
added at a future time.
The purpose of this research was to determine the ability of multiple diesel
fuel additives to replace the vital lubricity component in ULSD (Ultra Low
Sulfur Diesel) fuel.
ULSD fuel is the fuel currently mandated for use in all on road diesel
engines. This fuel burns cleaner and is less polluting than its predecessor,
called Low Sulfur Diesel Fuel. Low sulfur fuel contained less than 500 ppm of
sulfur. ULSD contains 15 ppm or less.
As diesel fuel is further refined to remove the polluting sulfur, it is
inadvertently stripped of its lubricating properties. This vital lubrication is a
necessary component of the diesel fuel as it prevents wear in the fuel
delivery system. Specifically, it lubricates pumps, high pressure pumps and
injectors. Traditional Low sulfur diesel fuel typically contained enough
lubricating ability to suffice the needs of these vital components. ULSD fuel,
on the other hand, is considered to be very “dry” and incapable of lubricating
vital fuel delivery components. As a result, these components are at risk of
premature and even catastrophic failure when ULSD fuel is introduced to the
system. As a result, all oil companies producing ULSD fuel must replace the
lost lubricity with additives. All ULSD fuel purchased at retail fuel stations
SHOULD be adequately treated with additives to replace this lost lubricity.
The potential result of using inadequately treated fuel, as indicated above,
can be catastrophic. There have been many documented cases of randomly
tested samples of diesel fuel. These tests prove that often times the fuel we
purchase is not adequately treated and may therefore contribute to
accelerated wear of our fuel delivery systems. For this reason it may be
prudent to use an after market diesel fuel additive to ENSURE adequate
lubrication of the fuel delivery system. Additionally, many additives can offer
added benefits such as Cetane improver, anti-gel agents and water
separators (demulsifiers). Some fuel additives include water emulsifiers that
cause the water to remain in suspension with the fuel.
Copyrightę The Diesel Place & A. D. Spicer - 2 - August, 2007
In this study we will test multiple diesel fuel additives designed to replace
lost lubricity. The primary component of this study is a side-by-side
laboratory analysis of each additive’s ability to replace this vital lubricity.
Additionally, claims of improving Cetane, water separation or emulsification,
bio-diesel compatibility and alcohol content will be noted. These notes were
derived from information that was readily available to consumers (via the
label and internet information) and none of this information has been
evaluated for validity and/or performance. Cetane information has only been
noted if the word “Cetane” was used in the advertising information. The
words “improves power” has not been translated to mean “improves Cetane”
in this evaluation. Information on alcohol content is provided by indicating
“contains no alcohol”. Omission of the words “contains no alcohol” does not
imply that it does contain alcohol. This information was simply missing in the
information available to a consumer. However, the possibility of a form of
alcohol in these products is possible. Additionally, information on dosages
and cost per tankful are included for comparison purposes.
How Diesel Fuel Is Evaluated For Lubricating Ability:
Diesel fuel and other fluids are tested for lubricating ability using a device
called a “High Frequency Reciprocating Rig” or HFRR. The HFRR is currently
the Internationally accepted, standardized method to evaluate fluids for
lubricating ability. It uses a ball bearing that reciprocates or moves back and
forth on a metal surface at a very high frequency for a duration of 90
minutes. The machine does this while the ball bearing and metal surface are
immersed in the test fluid (in this case, treated diesel fuel). At the end of the
test the ball bearing is examined under a microscope and the “wear scar” on
the ball bearing is measured in microns. The larger the wear scar, the poorer
the lubricating ability of the fluid. The independent lab runs every sample
twice and averages the size of the wear scar.
The U.S. standard for diesel fuel says a commercially available diesel fuel
should produce a wear scar of no greater than 520 microns.
The Engine Manufacturers Association had requested a standard of a
wear scar no greater than 460 microns, typical of the pre-ULSD fuels.
Most experts agree that a 520 micron standard is adequate, but also that
the lower the wear scar the better.

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.
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%
Copyrightę 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.
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
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”.

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.
Copyrightę 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.
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
You folks are the best.

Any from the list, top 10.
I use Power Service Diesel Kleen cause it can be found almost anywhere.
The 10 additives say pretty much the samething on the product label.
Iv tryed about 5 from the top 10 list the only difference I noticed was Power Service Diesel Kleen can be found in stores easily.
