I notice a mpg bump when I put in 2oz of their everyday EDT (small container, orangish color) at fill-ups. When towing heavy I notice it with their Diesel Extreme (larger jug, red color)

 

The EDT is what I have been running, until lately, in my truck. I have not used the Extreme when towing though. It seems like I read somewhere they don't recommend that because it causes a slight increase in EGT's, or something to that effect.

 

Lots of great reading here for an oil nerd like me. On my way to pick up a gallon of Optilube XL and a quart of Optilube Boost. Living in California where minimum cetane spec is 53, I really don't need cetane boost so just be getting a little for when I travel out of state. FWIW, I always fill up with genuine top tier fuel.

 

Awesome! Let us know how you like it.

 

I ran stanadyne performance for years, always seemed to work well. The other year I switched to optilube xpd I notced more black smoke, ran it for a year till supply was out and went back to stanadyne performance, just for giggles did optilube for a few tanks last year, again more smoke, this time on both trucks(didnt have 2 trucks before), so I will stick with standadyne performance.
I did no scientific research in this just butt dino and rear view mirrow watching:-)

 

Back when the 7.3L was new, the only diesel fuel additives that International and Ford recommended, in writing, were branded Stanadyne, with the exception of the Ford marketed PM-22 and PM-23 additives.

 

Didnt know that.
My work truck I have had for a long time was bought from a good friend. He is a top notch diesel tech and fabricator. He sent half a case of the stanadyne with me and said to use it, so I did. I always figured if he recommended it, it must be good. At that time I was just learning to change my own oil. It is funny now, cause he calls me with 7.3 related questions :-)

 

Are you able to tell us which current formula available resembles the Stanadyne recommendation of yesteryear the most?

Again, I ran Stanadyne Lubricity for years based on the spreadsheet noted above and the cost involved based on buying in bulk. I never really noticed a difference, but was not really paying that much attention to it either. It was just something I did when filling up the OEM and auxiliary tanks.

 

Stanadyne has changed corporate hands about 4 times since Ford first went on the record in 1994 recommending Stanadyne as a fuel conditioner. Even the founder and namesake of the parent company that now owns FTE used to own Stanadyne, for about 10 years. I cannot speak to any changes in Stanadyne formulas or their correlation with current product marketing names. I can only point out some of the Stanadyne products that Ford and International have recommended, in writing, under warranty, to the exclusion of any other diesel fuel additives, with the exception of the additives branded by Ford (PM-15, PM-22a, PM-23a).



Note: I forgot to underline the sentence in the screen shot above "Other brands of conditioners or additives are not recommended."

In subsequent writings, and in particular when the 1999 up 7.3L Super Duty, Ford and International recommended "Stanadyne Performance Formula" with the blue label. I purchased Performance Formula by the case when I bought my 2000 7.3L, after attending a diesel training session taught by the field service engineer at International, if that gives you any idea how strongly Stanadyne was recommended back then.

The real concern that Ford and International had was the potentially harmful aspects of some of the ingredients found in other diesel fuel additives on the market at that time, which they had tested.

For the next 10 years, I regularly dosed each fuel tank with Stanadyne Performance Formula. I kept a half gallon bottle, with a turkey baster, in one of the side boxes of the truck, near the fuel filler. I cannot report that Stanadyne was better or worse than other fuel additives, because I didn't try other fuel additives. I let Ford and International do that testing for me, and simply followed their recommendations.

I then bought Ford's PM products (by the gallon, in the metal can) when my source for Stanadyne at wholesale pricing dried up.

Additional Stanadyne products I've seen mentioned in Ford TSBs are the Lubricity Formula, and an anti gelling (although I do not recall the current trade name "Winter 1000" ever being mentioned).

The Performance Formula (blue label) covers lubricity, anti-gelling, and cetane improvement in one shot.

California diesel fuel was reformulated about a year before the rest of the nation was required to adopt ULSD.

 

I buy it by the case(actually usually 2 cases). One of these containers treats 30 gallons, about what it usually takes to top up my tank, which is very convenient.

 

I have run the Stanadyne in a Duramax, but not my 7.3. The guy at the local parts store I frequent is a fan of Stanadyne in his 6.7 PS, and I guess has been using it for several years in different diesels.

 

Which FPPF product was used for the study?

I see a ton of them listed on the website: https://fppf.com/product/

 

Line #16 in the chart states "FPPF Lubricity Plus Fuel Power" and page #8 (item #16) states the same.

FPPF Lubricity Plus Fuel Power link

Line #3 in the chart states "FPPF RV, Bus, SUV Diesel/Gas Fuel Treatment" and page #5 (item #3) states the same.

Since the treatment listed in line #3 is not on the FPPF product page, I can only assume it was discontinued. I performed a brief search for it, but I was not able to identify that product available for sale.

I hope this helps answer your question.

 

I would not use "FPPF Lubricity Plus Fuel Power" period.

FPPF has not released an MSDS for that product. I would need to see that first, to make certain that there were no alcohols in it.

FPPF can't even correctly spell what testing was "parformed" (sic) in FPPF's product marketing materials.

FPPF has released an MSDS on their other products, but unlike Stanadyne, which fully discloses the elemental concentration percentages and has nothing to fear or hide, FPPF, on the other hand, does not disclose the concentration of the regulated ingredients.

The FPPF product "Lubricity Plus Fuel Power" appears to be a blend, where FPPF has added "lubricity" to their Fuel Power product. So let's take a look at the MSDS of the FPPF Fuel Power product.

FPPF Fuel Power SDS

Only one ingredient listed. Glycol Ether. (Dipropylene glycol monomethyl ether). Since Glycol Ether is the only listed active ingredient (where FPPF obfuscates the concentration as a so called "Trade Secret"), we are left to assume that the main ingredient is glycol ether.

Let's get some help in understanding what glycol ethers are....

The initial materials for the preparation of glycol ethers are propane oxide (giving propylene glycol ethers) and alcohols.

Glycol Ether products are produced through continuous processes of selectively reacting an alcohol and ethylene oxide.

Now let's take a look at the MSDS of Stanadyne Performance Formula for comparison...

Stanadyne Performance Formula MSDS

Of note, on the Stanadyne MSDS, nine (9) ingredients are listed, including percentage range of concentration by weight of each ingredient in the composition, comprising the entirety of the product All percentages add up to more than 100%... no "trade secrets", no hiding, no magic black genie bottle hocus pocus bs). All CAS #'s are disclosed by Stanadyne for each ingredient, whereas FPPF fails to disclose the CAS # for the single and only ingredient identified in their Fuel Power product SDS.

There is a very small percentage (between 2 to 4 percent) of Ethylene glycol monobutyl ether in the Stanadyne product, presumably as a de-icing agent. The glycol ether links provided immediately above will help distinguish how this is different from the glycol ether in the FPPF product.

@MountainManRobb mentioned using Stanadyne in his Duramax, a couple of posts up. So let's compare what General Motors has to say about diesel fuel additives they recommend, versus what Ford says...

And finally, let's see what Ford says about diesel fuel additives for the current diesel engine that Ford produces:

 

Wow, interesting that the FPPF product was high up in the results even if it is not good to use.
