I have been using power service diesel kleen cetane boost and when I use it my milage drops by up to 5 gallon per mile... Any thoughts ? I have wondered if it was cleaning my injectors, I only used it in about 5 tanks and quit and the third tank without it I am back up to my normal 44mpg.

What do you recommend as lubricant for 2010 Jetta Sportswagen TDI Fuel Pump. I have 145,000 miles on car and replaced fuel pump twice because it breaks apart putting plastic throughout fuel system . Has been covered under warranty and VW said will not cover any more. I want to keep car for 300,000 or more miles and looking for a way to protect the faulty fuel pump that the dealer says is not getting enough lubrication. Open to your guys suggestions.

I read a few pages and didn't see anyone using Seafoam, I'm using it now in my 2002 Wagon and it seems to be giving me better MPGs so far.
Is anyone using Seafoam?
Thanks

Please, don't use seafoam in a DIESEL. Hopefully that's enough said.

Seafoam is described as a motor treatment, not as a fuel additive. It may not be harmful to diesel engines -- unless you add it to the oil -- but I can't imagine how it might be beneficial.

Actually, Seafoam can be added to fuel or oil. It specifically says so on the can. However, as it was noted, do not use it in oil or fuel on a DIESEL. I don't care if the can says you can use it on a diesel. Ask a diesel mechanic and they will tell you not to. However, I have used it on my gasoline engines with great success.

You can pour Seafoam into the crankcase of a gas engine to help break down and remove sludge. You can add it to the gas tank (not diesel) to help clean the fuel system. I have also used it on my gas engines by pulling off the brake booster line which goes to the intake and sticking it into an entire can of Seafoam. Just get your RPMs over 3,000 and the brake booster line sucks the Seafoam through the intake and cleans it out. But again, do not use Seafoam on a DIESEL.

I did some reaearch and picked FPPF, Deluxe Total Power (winter) and Lubricity plus Fuel Power (summer). It's like 3 or 4 oz a tank, my main goal is to proved extra lubricity.
There are better additives, FPPF makes better, Power Service and Lubri Moly are great products.
Other than those last 2, they can be hard to find, call the sales people at the manufacturer, they know for sure who carries what.

I would suggest that a good inexpensive, commonplace product is power service in the WHITE bottle....while it is an anti gel, it does have a water emulator in it...keeping water from settling out and then getting shot through the HPFP in a slug killing it....the gray/silver bottle lacks this agent.
I have been using the white bottle year-round, and sometime add a ride if the silver to get the extra cetain boost...yes, you can double dose...both provide lube, but only the white helps with water issues, which seem to be the cause of many HPFP failures.....and good CLEAN fuel, can have water settle out with a big change or drop in temperature.....
Seafoam is good stuff for some uses....use it in gas motors, to remove carbon, and treat GASOLINE, but due to the mix of oil alcohol mixing it with diesel is downright wrong. It can be done, just as it is possible to use isopropyl alcohol to remove water (the bottle of HEET SAYS SO!!)....but it is FAR from a good way to handle it....AND CAN CAUSE $$$$ Issues later...
Think what happens when the alcohol ladden water that has settled out into the bottom of the tank or filter does after it mixes up with the dirt, and has let algee grow, when it get pushed to the motor...just DO NOT DO IT. Nothing happens immediately....but you are setting the stage for thing too happen in the future.

People get odd when you talk about addatives...it becomes like a religious war....folks will ship stuff halfway around the country , devise the perfect dosage method, etc...
Me, I splash about what I need into a funnel....extra won't hurt...might cost ya a few ¢
But many DIESEL mechanic do fill a filter up with 100% power-servce in the gray/silver bottle to ensure a good start after a loss of prime....it is possible to overdose with the white, but pretty hard to do...and unless you use multiple bottles in a tank you are fine...
I can get POWER SERVICE locally, pretty cheap, especially when on sale at the end of winter...heck got some in the spring for about 30% off cause they were making space for the silver bottles....
Some folks use SINGLE PURPOSE addatives...some are just lube....some just cetain , some just to emulsify water....due to their fears of ONE issues...but fact is ALL the items can be an issue imo, so use a multipurpose addatives to prevent issues!!

First, I want to admit I did not read all 194 posts, so I don't know if anyone has suggested running a 2% blend of bio-diesel in your fuel. At that low of a percentage it won't rapidly clean your entire fuel system, but it will add enough lubricity to your fuel to keep your injectors happier than without it. Quick math here: 1 quart of (99%) bio-D in a 15 gallon tank is roughly 2% if you run it long enough it will remove pretty much all of the gunk in your fuel system from tank to injectors, of course if you want to clean out the gunk sooner than later, run B-50 (or higher) but make sure you have a spare fuel filter with you at all times.

"Lubricity Additive Study Results

--------------------------------------------------------------------------------

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 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”.

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.

As you are new here I will just inform you that this study was done in 2007 (a decade old) and has been posted here many, many times already and much discussion done already on the merits and problems with it. Read some of the threads here to inform yourself. I would venture to say there is no "best" and if there is even a little bio in your diesel you will be just fine (assuming you aren't fighting water or cold issues).

It actually came from here:
