Additives to diesel fuel when using ULSD

What additives, if any, are recommended to use to offset the low sulfur content in the new diesel? Is there any "proof" that the new diesel has any negative affects on the 7.3 motors?

I would recommend DieselKleen. but I dont use it myself except for in the winters. I just dump some tranny fluid in my fuel when I have some layin around.

Someone else will chime in with some more concrete answers

the "affect" is loss of mileage/power. I run waste oil, and some of the powerservice stuff too when ever I catch it on sale

This question has been discussed in dozens of threads....

Here is, what has become, the definitive study

---------------------------------------------------------------------------------
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 Sulfer Diesel) fuel.

HISTORY:

ULSD fuel is the fuel currently mandated for use in all on road diesel engines. This fuel burns cleaner and is less polluting than it’s

predecessor, called Low Sulfer Diesel Fuel. Low sulfer fuel contained less than 500 ppm of sulfer. ULSD contains 15 ppm or less.
As diesel fuel is further refined to remove the polluting sulfer, 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 sulfer 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, and water separators or emulsifiers.

CONTENT:

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. Southwest Research 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.

METHOD:

An independent research firm in Texas 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 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. This fuel was tested using the HFRR at the Southwest Research 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 bio-diesel 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% 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 An independent research firm. 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 Research 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, non-conventional, 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”.

I use AMSOIL Cetane Boost Diesel Fuel Additive and AMSOIL Diesel Fuel Additive Concentrate. I have personally seen about 2-3 mpg increase, quicker starts, less pinging, and it also smoothed out my idle from dirty injectors.

The Cetane boost does just that boosts the cetane levels up about 7 points. The EPA mandates a min of 40ppm of cetane.

The Diesel Concentrate is a cleaner and lubricator. Increases fuel milage by cleaning injectors, reducing deposits. Ultra low sulfur diesel has significantly reduced lubrication which can be hard on your fuel pump and injectors. Using oil in your fuel by itself only provides lubrication and does not clean or increase cetane levels.

Let me know if you would like a quote on any products.

I use DieselKleen only because I picked up a bunch of it on sale.
Using it, I notice my injectors are a bit quieter.

Where can you get 100% biodiesel to put in as an additive? Would that just be pure vegie oil from the store?
