Addatives for lube oil?



This not new , but may be news to you!

"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.

PURPOSE:

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 its 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 additives 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.

CONCLUSIONS:

Products 1 through 4 were able to improve the unadditized fuel to an HFRR score of 460 or better. This meets the most strict 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.
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 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 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. Arlen Spicer, organizer."

Yes this is not new news but good to see it posted here.

A note on the testing method..... As a mechanical*engineer I have had materials tested using this same method and the results are very repeatable meaning it is a good and valid testing method.

"When do we get to the lube oil additives??"

IF lubrication is a worry , a bypass filter (most any brand) is a huge help , as is a pre-lube setup.

Added Goop in the oil ? I have a bridge in Brooklyn for ya!

And there is NOTHING better than having a good lab look at the oil on each change , $15 or $20 really well spent.

FF,

The thread should be Additives for FUEL oil.

I agree Fred * *...the bypass filter is a very good idea.

RE: Addatives for lube oil?

Lately I have been topping off at a marina that sells Valvetect marine diesel, which is supposed to contain "BioGuard biocide, lubricity improver, water dispersant, corrosion inhibitor and fuel stabilizer and is specifically formulated to prevent problems caused by the reduction of sulfur content."

I wonder what lubricity improver they use specifically?* Seems like many of the high volume marinas in my area use this brand of fuel.

RE: Addatives for lube oil?

"water dispersant"

Here is a big danger as it could be an emulsifier , that grabs the water , and will pass emulsified thru your filters.

Could be a de emulsifier that drops the water to the bottom of the tank , where it can feed bacteria colonies , or be pumped from the tank sump.

RE: Addatives for lube oil?

An old farmer once told me it's common practice for farmers to add ATF to their fuel as a lubrication additive. Has anybody else ever heard of this, or know the upside and downside of doing this.

*Peripheral to hobbyists brewing their own biodiesel there's a group called "blenders" who spend their time trying to make waste oil burn cleaner in diesels by adding ATF, paint thinner, alcohols, industrial solvents, white gas, and moth balls.

*

Sounds dreadful, but when you read the MSDS for commercially available magic diesel juices you find active ingredients like mineral oil (ATF), xylene, benzene, mineral spirits, stoddard's mixture (paint thinners and industrial solvents), alcohols, naptha (white gas), and napthalene (moth balls).

*

I've yet to see any real science showing a clear benefit to using this stuff. What is usually presented as "science" would get a second year engineering student punted all the way to the Faculty of Business.

*

It does show that diesels are amazing tolerant pieces of engineering. I believe Rudolph Diesel's demo ran on peanut oil.
