Dr. is right! Let's keep on task here and just omit the name calling and such.

Zmax seemed to work on one of my vehicles. This post contains everything I know about Zmax

Here is the only side by side comparison of additives for fuel that I know of: Dieselplace Spicer Additive Test
Because of this test I quit using P.S. since it actually lowered lubricity of the fuel. I tend to believe that major companies will just do the minimum when it comes to adding things to their products. There are examples of this everywhere. Chevrolet ships every new car to the dealer 1 qt low on oil. The dealer is the one who gets to pay for that additional quart of oil. Not a big deal you say: well just think of it this way. If a qt of oil costs $2 and you shipped 1 million cars last year - you just added $2 million dollars to your bottom line. Many years ago, car makers were leaving off the grease zerks on new cars. Same principle. If they were saving $1 per new car then they were actually adding millions to their bottom line by not supplying the grease zerk.
I can promise you that if we were to get fuel from various stations and test it, then it would be very near the minimum requirements for lubricity.
It's just like when I worked in the electrical industry. The wire manufactures state that a roll of wire will be + / - 10% of it's stated length. I didn't measure every roll of wire but every one I did measure was always - 10 or -12%. I never got one that was over length or even what it was supposed to be. I think there is a reason for that. It is always because of the bottom line. There is usually some 'wise' explanation but they usually don't hold up. Chevy states it is because the robots that fill the crankcases just cut off the fill too early. I for one know that if a machine can be consistent then it can also be consistently right. It doesn't take a rocket scientist to know that if you program in 5 qts and the machine always gives you 4 then you just program it to dispense 6!!
Here in America we are stuck on the idea that everything has to have a warranty. Have you noticed how the Chinese are dealing with this? Ever wonder why most things they produce completely change very often. If they make it different every few months, then you can't go back to the store expecting to get the same thing. If it isn't made anymore then you can't get another under warranty. Kind of a sneaky way to do away with the warranty isn't it . . . .

(On a side note: we used the same text book in our college class. Excellent book I might add. I didn't notice the section on fuel or at least I don't remember it. I just might have to pull it out again and see what it says. I have a scanner . . . . )

You guys keep any and all info you have or can find on fuel additives coming. I think there is a lot we all need to learn. I am also sure that fuel changes quit often. Because of that we all need to stay on top of those changes and try to do what is best for our rigs!

Or like Ronald Reagan said: "Trust, but verify." I can't verify what's in the fuel I buy, so I'll just take care of it myself, thank you very much.

As fas as machinery lubrication is concerned, generally speaking, I'm not sure there even is such a thing as too much lubrication within the range of proper fill levels and so forth. But a whole helluva lot of them damn sure were destroyed by too little lubrication.
Here's the story, if you really want to know... :w2:

Stand up company that has been making fine oils for several years.

I run Mileage Max in my Chipped Power stroke. It is a great product and i swear by it!
It especially important now with the Now sulfur Diesel fuel. I Know i ran into alot of problems when the fuel switched a couple of years ago and i was told that the new low sulfur diesel had alot to do with the problems that i had. i have since not run into it since adding a additive to the fuel. most of the problems i had with my powerstroke had to do with low power and poor fuel economy. But now im Stoked that i can lay a strip when ever i want to. :]

ZMAX, Slick 50

Dont put it in a tired anything.... had an old chevy w/396 and it was pretty tired... the additive caused major blow by ( compression went to hell), a mild knock turned into about 7 knocks and loud as it gets.... had to park it and rebuild before i wanted to. Could have gotten another 50k outta her had i kept running mud, im sure of it.

Did run it in the wifes lil Jap truck and at 175k all is fine but you can do that with oil changes and some TLC no prob, now when she gets to 300-400k i might begin to think it is actually doing something worth while....

i can do 2 maybe three oil changes for the price of the additive... so till i got it in some sort of proof to myself.... it stays on the shelf lol

JMHO

Really, why?

If your going to make a post like that you better back it up with some useful information.

So you're working for them?

Alrighty, then! So now there's like what about a dozen fuel adds claiming unbelievable MPG improvements?

I'll leave the the fuel mileage issues to my right foot, thank you very much. That's not what I want from a fuel add.

I was liking what I was reading on their site until I dropped into their forums and read this reply from the company: (When asked: "Will I see immediate improvement in my fuel efficientcy")

"In most cases YES. For some older diesel engines it may take 3 or more tank fulls. With pre 2000 model yr engines the fuel economy was so bad that even a 20% increase is hard to notice. However you will still help your diesel last longer by cleaning the fuel system and giving the engine the lubrication needed to run todays ULSD fuels with no fear of mechanical break down due to dry fuel."

I'm sorry, but everything I know points me to the fact (/belief) that older diesels get better mileage! In fact, the worse mileage possible is out of the newest emisson laden diesels! So, I decided that I didn't like what I saw on this additive . . . Besides, even a class 8 truck that gets the poorest mileage of all can and do find smaller increases in mileage and go after them. So just the part of their statement that it is too hard to measure / track mileage increases when getting such low / small mileage numbers to begin with is a very poor understanding of the real world. To me it just goes to show that most people really don't track their mileage or know how to . . . . :pca1:

I just couldn't resist. Here is another quote from the company in their forums:

"Hello and thank you for your questions. The lab we used was and is the test lab for the EPA in our area. The EPA must test all additives in order to be sold to the public. A lot of additives do not do this testing. The problem is there are no EPA police to stop them from selling their snake oil. We wanted to be sure what we produce is the best additive available. The testing took us 5 years and the EPA lab 1 yr. The lab results are the only true way of testing. In a lab you can control the tests in a more efficient manor. In the real world or driving tests it is very hard to match like conditions. Since the variables are to great. Such as how hot it is at testing, road conditions, tire pressure, wind, weight in the test vehicle etc. What we have seen with our clients are a range of 10% to 15% and is some cases as much as 18%. We truly do have the latest technology in diesel additive

To read the test results better, click on one of the chart graphs. On each page it will give you the definition of each category. The base line was just pure ULSD and run for 200 hrs. Then the lab added Diesel Fuel Boost. You can see the difference between the two.

Our secret is in our ability to increase the BTU of diesel fuel, without creating additional heat. As you can see the horse power stays about the same. Other additive companies want you to think that by adding cetane and creating more horse power you save fuel. This is a fallacy in the additive and diesel fuel world. Cetane is a unit of measure only. It does provide better starting and engine smoothness but does nothing for horse power of fuel economy.

I hope this answers your questions. If not please don't hesitate to ask away.
Thank you."

:scare2:

In plain words it all BS.........

Obviously you haven't been around here long enough to see some of my other posts on this subject. So why don't you just use the search function, and I'll leave it at that. :argh:

Just got back from the Gulf, Volunteering with cleanup efforts & filled the 70+ gal tank with just diesel fuel on the way there.
On the way back, I added aprox 1/2 can of the "Diesel Treat 2000" Premium Diesel formulated with Synshield Lubricity tech. that I recieved free here through DB's.:choochoo:
I must say, I was impressed after only about 10 min heading down the hwy.
Started running better, climbing hills better & better milage oh yeah!
Fuel Injector Happiness is a very good thang:tu:

Oh, I almost forgot!
It took 1 & 1/2 tanks to get there and a little more than 1 & 1/4 to return.:c:

i hear alot of "iv put this is my truck and its still running, so it must be a good thing to put in the fuel." but has anyone actually done dyno tests or mpg tests, or a before/after test on the fuel system to find out if these additives work at all? im not convinced by the logic of, i put something into my fuel, my truck didnt blow up, must be helping.

so has heath, or anyone for that matter tested the additives?

I agree no additives ever in my fuel
 

But I have a close friend who drives over the road for Werner Continental I think they may have merged with Swift, and he told me that there maintenance department adds this to there fuel...Penray Total Diesel Fuel System Cleaner and it is used on a regular bases...I have been adding 2 Oz. of this to every tank of fuel in my truck since it was new....So I can't say there is any benefit to it or not...But I have never had a fuel system problem...My 6.7 Cummins only has 30,000 miles on it...

All you need to do is keep the system clean
 

Change fuel filters every 10,000 miles and purchase fuel at stations that sell a lot of it...Preferably large truck stops if possible...This along with frequent oil changes and your diesel should serve you well for 300,000 miles or more...

Keeping the fuel system clean is not all the story
 

I agree that keeping things clean is helpful, but an additive is needed for maintaining injectors, injector pumps, and lift pumps.

Benefits
• Lubricating the fuel & injector pumps.
• Improved mileage and fuel economy.
• Fuel atomization results in more complete fuel consumption.

Lubricity-enhancing compounds occur naturally in diesel fuel, but hydro-treating to reduce sulfur levels can alter these compounds. As diesel fuel is further refined to remove sulfur to comply with federal regulations, it is unintentionally stripped of its lubricating properties.

Hydro processing removes sulfur along with significant amounts of aromatic compounds that give conventional diesel fuel adequate lubricating capability. This vital lubrication is a necessary component of the diesel fuel as it prevents wear in the fuel-delivery system. Specifically, it lubricates high-pressure pumps and injectors.

Diesel fuel injection equipment has some reliance on lubricating properties of the diesel fuel. Low lubricity in diesel fuel can cause major engine problems. Measurement of diesel fuel lubricity is important to monitor lubricity additives and final fuel quality.

Traditionally, fuel viscosity was used as a rough indicator. The ability of diesel to effectively lubricate engines and components has declined, however, with the introduction of newer low-sulfur diesel fuels and more stringent government regulations.

Diesel fuel pumps and injectors rely on the fuel itself to protect moving parts from wear. Diesel fuels with poor lubricity can lead to pump wear, injector deposits, clogging and eventual vehicle failure. Lubrication properties have become a key parameter of diesel-fuel specifications.

Hope this helps clarify the need for a fuel additive. It is true that not all additives are the same, so doing some research is prudent to cost justify using any additive.

pure diesel fuel WILL GELL in cold temp's, it must be blended or treated, in the winter most is, some isn't. Some has water in it. Some bio has microb inhibiters , some doesn't. Use some additive, occasionally, and carry a spare fuel filter, or not, good luck.

Hello:

I have tried several fuel additives over the years. Some of the brands that I have tried are:

Enviroleen - G
Jectron Gas Treatment
Freedom Fuel Additive

They all seem to do a good job and they are not that expensive!

Anybody use Power Service Diesel Kleen?

Fuel Additive
 

Sure, I have used it, but I switched to Lucas fuel additive. Lucas was cheaper, and easier to use at 2 oz./10.0 gallons of diesel. The Lucas fuel additive is "Upper Cylinder Lubricant & Injector Cleaner. " I also use Howe's Lubricator since it is an anti-gel for winter driving.

Hope this is helpful. Good luck.

I use it on my truck, every once & a while, I do get better mileage with it, a small gain in MPG:humm:

I have a 12V .. I have ran atf, 2 strke and DK ... @ stroke ( ashless NON-syn) .. its almost as quiet as our LB7 ... EVEN cold ( 10*F) .. :tu:

XPD here, although my truck was designed for ULD. Some parts have fallen off, but I use an additive anyway. If you do some research here on the blog there is a post showing results of all different additives compared in a blind test and how they line up with the results.

Wally World 2-stroke tcw3 outboard motor oil for me. I use a more conservative half-quart to a tank with a touch of PS Diesel Keen. Been doin this for years. My CTD is MUCHO HAPPY. :yeah:

We all run different years, brand of trucks, different engines, so what may work in an old Dodge, may not work in a Ford 7.3 and what works in the older engines may not work as well or at all in a newer engine. And with the newest emission controlled engines...well be careful what you put in that fuel. Dont want your DPF exploding under the truck! I've always used Stanadyne, ever since I had a 6.2 GM (Detriot) But I've been hearing good things about the Amsoil additives. I'm sure it depends on where we buy our additives, some are only available on line, others can be found at WalMart. As for testing, I'll leave that up to the labs, as I can't run the exact same load, same temperature, same traffic/construction all the time. I run a 90 Gal aux tank, and a 50 gal under bed tank. A bottle of Standadyne does 20 gallons and I put a bottle in both tanks. if I'm almost empty and 1/2 bottle in each if I'm about half full. Where you get your fuel has more to do with fuel mileage than an additive. But I add it to help lubricity primarily, anything else it does I hope helps. Sorry I can't post some long article or advertisement.
I'm sure most additives help with lubricity. Most wont hurt your engine or economy. Yes I've used 2 stroke oil in a 7.3 and GM 6.2, would I use it in my F450 6.7? no I wouldn't.
When we changed to LSD (low sufer diesel) alot of the older class 8 trucks had real bad problems with pumps and injectors, same thing when we went from LSD to ULSD I would hope that the OEMs would have built fuel pumps and injection systems to be compatible with the ULSD. And that most fuel suppliers wouild add enough lubricating additives, But as was stated before I'll continue to add some, just in case.

Agreed! Anyway you look at it, its cheap insurance to help safeguard IPs and injectors.

anyone ever run ATF in a common rail? im using power service right now with howes in the winter ( we hit -40 C here ) but an ol boy from way back i work with told me ATF is by far the best lubricant for a diesel, then again diesel trucks to him are still gm 6.2's :w2: anyone ever done it or know if its safe for the cp3/injectors? :pca1:

ATF wasn't made to burn, I wouldn't use ATF, I would keep using POWER SERVICE:humm:

ATF belongs in an auto trans.

apparently the older stuff was alright but the newer stuff isn't... kinda like most things in life :humm:

Wow..... thats deep bro.....:word:

XPD here. Search for the thread, about a Blind Test with regards to all the aforementioned additives plus some. I found it to be useful.
