Did a search but did not find much. I have a 2017 F350 DRW. I see a few posts about additives like Diesel Kleen. Should I be adding something to my diesel? I've owned a few diesel trucks but have never used additives. I also know very little about engines.

I have a 37 gallon tank and add 16oz of Diesel Kleen in every (full) fill-up.. 1/2 tank gets 8oz...

My long term experience is more with diesel cars, and the most important thing is being religious with maintenance, much more so than with gas engines. Never delay or forget fuel filter replacement, along with everything else. Additives are a nice-to-do, not a need-to-do, nor a substitute for maintenance. I also think it's important not to baby them like a gasser - whether car or truck, diesels love to WORK.

Having said that... I've been using PowerService for years in my diesels... personal vehicles, I'm not some sort of fleet expert. 15 years ago I put half a mill on a VW diesel in 5 years and my engine was as clean and tight as day 1, and PS was a part of that.

My concern is for my older, 24V Cummins. The injection pump was designed before ultra low sulfer diesel was mandated by the feds. The lubricity of the ULSD was reduced, as a result, so I add Diesel Kleen according to the ratio recommended on the jug to compensate. Diesel Kleen also cleans the fuel system and increases fuel cetane (Google it). Walmart seems to have the best price, BTW.

While not really a snake oil guy, there are additives (snake oils) in gas, diesel and oils for our rigs and other things in life. I plan to keep my truck for awhile, so scheduled maintenance and proper injection pump lubricity is important to me. If you regularly trade in your vehicles, you probably won't see the benefit of the diesel additives.

I also carry a spare fuel filter in the truck (and have never needed it), but others have with a bad refuel of diesel. I just don't want to be stuck in "east dying cactus" on a weekend without a spare.

Yep. Heard good things about PowerService. Diesel Kleen is just more easily available for me.

www.bobistheoilguy.com (I think) did a comparison on diesel additives. Some work better than others and cost more/less than others. I think the important thing is to get one that provides lubricity, cleans the system and increases cetane, rather than just one that is just a cetane improver.

Have 150k on my 2011 dmax, never use additives. I have added a FASS system and change all three fuel filters every 25k miles. Runs like the day I bought except quieter due to the FASS system removing the microscopic air bubbles which create injector noise.

I normally dump in a bottle of something once a year. diesel kleen mostly. Here's a question for anyone. I use it before a long trip. Thinking why put it in a tank that may sit for a month. My way it runs thru the engine that day under a load. Good /bad does it make any difference?

Since Texas allows up to 20% Bio-diesel, and hen's teeth are easier to find than straight #2 fuel... most stations are 5% to 10%...

With Cetane rate all over the board, I run it in every tank...

I could hear, see and feel the difference within the first tank.. Quieter, smoother and better mileage..

Locally I seldom use any additive since NY only allows up to 10% biocrap. I do use the summer Diesel Kleen when we are traveling since some of the Midwest stations specifically state that there is 20% bio which in turn reduces my towing fuel mileage from a respectable 11-12 mpg down as low as 9-9.5. I have read a couple articles that have said that in tests, that the 20% is no more then a WAG and it could be a higher percentage from stratification or even on occasion, less for the same reason. Supposedly bio negatively affects the cetane rating and can take it below 40 --- well let's say that a few ounces of an additive might just bring it up a bit. Most additives will also improve the lubricity of the fuel and maybe improve the life expectancy of those various tender models of Bosch HP fuel pumps that most late model diesel pickups now use.

Then there is the winter white jug of Diesel Kleen which will prevent waxing in sub zero temps. I do use this when we have a cold snap and need to leave my truck outside for some reason

There are several brands available but the Diesel Kleen brand is at every Walmart, NAPA and truck stop. I've wanted to try the Optilube and the Ford PM-22 version, but availability isn't that great.

Is it snake oil - beats me but it can't hurt anything and might actually help. My jury panel is still out:hide:

I put 4 ounces of Ford PM-22 in every tank; Diesel Kleen and Power service should provide the same benefit. I'm not sure it is required, but I consider it cheap insurance. I have also installed an additional filter/water separator on the truck as insurance against getting a bad load of fuel.

I could hear, see and feel the difference within the first tank.. Quieter, smoother and better mileage..In my older car diesels I ran B80 and B100 all the time in summer. If it was good quality (not fly-by-night) it was actually very good for the older diesel engine, especially lubricity, but you lost cetane numbers - not alot but you would notice if you were a high mileage guy like I was. It cleaned the fuel system right up though. I always had to get braided steel fuel lines, but that's about it. I would run it every few tanks. I had also run straight canola oil a bit (only in summer) in my old 2003 VW tdi, and it ran fine, but it can do some nasty things to fuel filters over time if it isn't heated
so I didn't go full longhair hippy. My friends running used fryer oil were always replacing fuel system parts but they got free fuel.... Pyrrhic victory I think.
With the more modern fuel systems, I would have to think straight veggie oil is a recipe for disaster, like you might get laughed out of the repair garage.

Does the B20 create problems with the larger displacement diesels?

It don't cost that much in comparison to the cost of the truck. Supposedly don't hurt anything. I'm trying to get in the habit of using it all the time. I definitely use it on the road when I fuel up at truck stops. They (Flying J) usually have 20% bio.
I hate truck stops.

The primary concern of this study was lubricity. As I mentioned before, I think if one were to use a diesel fuel additive it would be more productive to use one that provides lubricity, cleaning and a cetane increase.

Thanks Jim
For some reason I couldn't find the 2105 study. We're traveling and not using our standard browser.
Appreciate your checking on this. I was pretty sure the results were the same.
Basically just a 1/2 gallon of Biodiesel per tankful. It's good fuel so you don't have to be overly critical of the mix ratio.

For me, it would be easier to carry Diesel Kleen rather than have a 1/2 gallon of biodiesel at each fillup...which is usually a half fillup. Biodiesel is hard to find (thankfully) in my area.

Currently, I'm buying diesel for $2.29/gal, so a few ounces of additive don't really break the bank.

I manage a 19,000,000 fleet of heavy equipment and have extensive training in the teir 4 diesel engines. These system are very much like electronic fuel injection in the auto industry. Not much lubricity in gasoline so I don't believe lubricity is an issue in today's engines. In older mechanical pump and injector engines maybe but ultra low sulfur diesel has been around for a while. I would be more concerned with bacteria growth in biodiesel fuel. I think those of you that don't use you TV much should use additives that kill bacteria build up. Our research indicated that is the major issue. Not an problem if you drive regularly. As for additives only needed if your fuel is sitting for a month or more. our motto is " Its only as good for the first tank full" i don't use anything in my truck as we drive it regularly. Regular maintenance is best

Like I mentioned in a previous posting, my injection pump was designed before ULSD, so I use an additive. If I had a new rig, I might not use an additive unless I was concerned with the cetane level during the winter months when higher cetane is important.

Do you have any experiemce with the FASS fuel filter systems on Class 8 trucks?

check this link. http://berkeleybiodiesel.org/useful-guide-understand.html

a Berkely study suggest biodiesel actually adds lubricity to ULSD.
Here is a quote
The other main property of biodiesel fuel that we will discuss is its lubricating properties. It has much better lubricating and a higher cetane ratings than today's lower sulfur diesel fuels. Adding Biodiesel also helps in reducing fuel system wear. The fuel injection equipment depends on the fuel for its lubrication. The biodiesel fuel properties increase the life of the fuel injection equipment. Giving better lubricity and a more complete combustion increases the engine energy output, thus partially balancing for the higher energy density of petrodiesel. Older diesel Mercedes are well known for running on biodiesel.

As for the the fuel system you mentioned. The use of a water separator/primary and 3 micron secondary fuel filter is standard on 30,000 psi common rail systems.
Never heard of nor can i find anything on the effects of dissolved air in diesel fuel but it only make sense that the fuel would be less dense

Uf only that was from an impartial source instead of the cheerleader for biocrap, it would have, IMO, some more credibility. I can believe the lubrucity but have a hard time with better cetane numbers when my experience after the past two summers of significantly lower fuel mileage and perceived more throttle and the actual need for more lower gear use while traveling the Midwest and 20% biocrap. Others on Ford truck forums have noted similar results. I have also noted in states with 100% diesel, no bio, my fuel mileage went even higher then home, NY State' where they add up to 10%. This is over a period of just under 20,000 miles, about 14,000 miles towing the sig 5er so it's not a flash in the pan - seat of the pants.

Been thinking of this for awhile. A FASS Titanium system is on the schedule for next month.

I debated for a long time about the cost vs return on investment. I read about how the high pressure injectors are designed to close on a cushion of fuel, but microscopic air bubbles can cause them to slam shut on air instead of the cushion. Over time it causes wear and eventually injector failure. I have installed two systems now, one in my truck and another in a friends. I can tell you both were noticeably quieter after installing the system. This isn't just imagined, when you first start the truck after installing the system it takes about 20 seconds for the new fuel to reach the injectors, you will no it when it gets there when the noise from the truck suddenly drops by about half and starts running smoother. The only thing I can contribute the noise reduction to is injector noise as they start closing on the cushion of fuel. With a new set of injiectors in the $3k range, the $600 spent on the FASS suddenly seemed worth every dime. I also use NAPA gold filters on the system since they are easy to get and have some of the best filter ratings of any filter on the market. I also left the OE Rocor filter in place, I have no doubt my engine is getting clean, air free fuel.

Wow that's a lot equipment. As for your second post with the quote about Bio I would have to ask Who paid for the study? I have yet to read a positive review on Biodiesel from any group actually using it. By the way, comparing gas vs diesel is apples vs oranges, the least of which are the fuel pressures as diesel is typically 3 - 4 times greater.
I'm not a diesel engineer or researcher so I can only relate my own real word experiences on the matter. My personal choice is Diesel Kleen®. It has raised my mpg slightly and absolutely reduced the "diesel clatter" in my truck and is available at Wal-Mart and most auto parts stores. As a disclaimer, I'm not a "additive" type guy as my 50 + years of shade tree mechanics and extensive reading habits have made me a sceptic on "snake oil treatments". With that said, when I find something that real users (not the advertisement folks but the countless numbers on the many blog sites and speaking with mechanics, truck drivers at fuel stops, etc.) report on in a positive manner than I will try it out and make my own assessment. This has resulted in my use of Diesel Kleen®. Others may have a different experience.

I agree that advertising hype is not the best way to decide on what product or process to use. Likewise anecdotal information can also be just as biased or even inaccurate. Here is the link to the blind test results performed by an independant lab posted earlier, paid for by both the product manufacturers and dieselplace.com a reputable diesel users forum.

My company has over $325,000,000 in Florida alone. we've done our home work. Today's diesel fuel injection is very much like its gasoline counterpart in terms of theory. electronically controlled injectors being controlled by an ECM that get its input from various sensors. I don't claim to be an expert on the efficiency of biodiesel either what I've learned is that B20 is only 2% less efficient than ULSD adds additional lubrication and less emissions. I do believe that increasing the cetane level will improve economy to a point but it will do that with ULSD also. I think people tend to form an opinion without doing the proper research and there is some much out there it is difficult to determine what is true or as you put it "who paid for the study" I agree. I tend to stay with what the manufactures suggest because "they made it" and know more than i do. :iagree:

Being that the Ford additives are only available at the dealer I usually opt for the Power Service every 3rd or 4 th fill up I usually don't go below a half tank of fuel before fillup but I have pretty good quality fuel localy too ( no bio diesel). Planning a filter change at 15 K but I don't even have 10K in the truck I got in Feb of 16. I think a lot depends on your fuel source.

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”.

1) 2% REG SoyPower biodiesel

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.

Completely anecdotal, but here it is...

My friend and I both bought our 2003 Ram/Cummins within months of each other. He put his miles on about twice as fast as I did. I found that I could closely anticipate when something would go bad on my truck, by how long it lasted for him.

Then came the fuel injector issues. Both of us had to replace our fuel injectors at the same time. He had nearly 300,000 on his, I had about 140,000 on mine.

I couldn't imagine why mine failed so quickly. What I came up with is that we both started using the mandated ULSD fuel at the same time. I've used Diesel Service regularly ever since.

2016 Passport GT 2810BHS, 2016 F350 CC DRWThe last paragraph said anything with results of +/- 20 microns were considered no significant change. That is where products 10-15 fall.

I debated for a long time about the cost vs return on investment. I read about how the high pressure injectors are designed to close on a cushion of fuel, but microscopic air bubbles can cause them to slam shut on air instead of the cushion. Over time it causes wear and eventually injector failure. I have installed two systems now, one in my truck and another in a friends. I can tell you both were noticeably quieter after installing the system. This isn't just imagined, when you first start the truck after installing the system it takes about 20 seconds for the new fuel to reach the injectors, you will no it when it gets there when the noise from the truck suddenly drops by about half and starts running smoother. The only thing I can contribute the noise reduction to is injector noise as they start closing on the cushion of fuel. With a new set of injiectors in the $3k range, the $600 spent on the FASS suddenly seemed worth every dime. I also use NAPA gold filters on the system since they are easy to get and have some of the best filter ratings of any filter on the market. I also left the OE Rocor filter in place, I have no doubt my engine is getting clean, air free fuel.

FASS Titanium just installed. The biggest difference I've noticed is how much smoother and seemingly a bit more powerful the engine runs with not much fuel in the tank. With the sloshing and resulting aeration of the fuel in the tank it affected how the engine ran. I'm impressed. Will check mileage over the next few tanks. Might even be a little quieter.

Did you ever get those mileage figures?

Not yet. Only done some various towing and sitting for the past two weeks. Will post the mileage when I have some comparable data.

Seems to be making more power though. Was holding 25# of boost at 1200 EGT on a constant grade pull in 5th gear with the 326SRX. Never was able to do that before. Prior to the FASS, EGT would only allow 18-20# of boost before reaching 1250dF.

I'm liking it. :thumbsup:

The increase in mileage seems to be a steady 1 MPG.

Hi guys,

Sounds like most folks here either use nothing or seldom use anything, I go the other route entirely! Ha Ha. Since I couldn't find any evidence it can do any harm, and I had such good results the first couple times I used it, I now add 5.25 oz. of Lucas at every fill up. Adds 1-2 mpg, keeps the truck idling steady at 699 rpm (I use a digital display with an obd2 scanner), also the truck runs 2db quieter (used an app on my iPhone to test that) and lastly it appears to have a little better acceleration although my 0-60 times (measured by my scanner and Torque Pro app) don't reflect this, it's probably my imagination.
I'd like to point out that when you buy the gallon jug it comes out to only $1.19 per tank, which is about equal to a third a gallon of diesel so it definitely pays for itself. The small bottles at the truck stop are usually about $4 for the 5.25 oz.
1 gal = 128 oz which is 24 of the little bottles.
