Hi Everybody - New guy here.

I took delivery of a 2013 F-350 LB, CC dually, diesel, Platinum in May and have about 5,500 miles on it. Will use it to tow a fifth wheel. Love the truck.

Based on what I've read on several forums, I've been adding Ford's PM-22 diesel additive since day one and will continue to do so as a preventive measure to increase the lubricity of the fine #2 diesel we have nowadays. I was buying the 20 oz. bottles but the other day I bought the gallon container which is also available (PM-22 Gal !!). I'm going to get a small pump to replace the cap and will then just refill the 20 oz. bottles - much easier to carry and use the bottles. But cheaper by the gallon.

So here's my question: The dilution ratio on the 20 oz. bottles is 4 oz of PM-22 to 25 gallons of diesel. When I picked up the gallon from my Ford dealer I started reading the sticker on the can and it states the dilution ratio is 4 oz. to 31 gallons of diesel. And yes, it does state right on the sticker that it's PM-22. And the dealer did have to order it (I had to tell them it really did come in gallons) so I believe it's fresh product that they didn't have back in a corner somewhere.

Does this make any sense ? I immediately talked with the diesel truck service manager who had no clue. Can anybody explain this ?

Thanks much.

It would be unfair and incorrect to call it snake oil, but let's say it's a little like baby aspirin. It may do a little to ease your pain or slightly reduce risk of heart attack over time when taken regularly, but it's hard to under- or over-dose on it. Fudge factor is very high, because there's really no such thing as too little added, and it takes a whole lot to become too much. In fact, most commercial products recommend adding twice the normal suggested dosing if you want, normally because they say it'll clean this or that system. So if you're off by an ounce or two, it's not that big a deal.

 

parts man at evergreen ford Issaquah wa looked into this for me. he said ford people said it's the same product. as to the pm22 gal ratio 4 oz to 30 gal is fine for my 2010 6.4. putting more in isn't necessary, the recommened rato does the job. pm22a at 4 oz to 24 gal apparently more than necessary. 1 gal 50$ , treats 1000 gal, 8$ for 20 oz treats 125 gal, do the math and see the discrepancy.

 

Tim Welcome to FTE.
Please if you find a pump that the stuff does not eat up
or dry out so much you can't pump the fluid let us know.

The plastic gear oil pumps can't stand the compound.
They stick and come apart.

PM22 is for pre-emissions diesels, PM22a is the reformulated ULSD/DPF compatible version that you need for the 6.0, 6.4, 6.7 and up.

I've been pondering the pump thing for a while and kicking around an idea for a built-in dosing pump to install on the truck where you can keep a gal jug in your truck box and just cycle the pump to dispense the appropriate amount.

Does anyone happen to have a materials compatability list for the fuel conditioner? I've got 304 stainless stock on hand I can make the pump out of and stainless ***** and springs for check valves are readily available. Just not sure what seals will hold up to the stuff.

ETA:

Looking again at my stock of 20oz bottles and gal jugs it seems the labels have changed and the part number has even dissapeared from some. Presumably here in 2014 the backward compatible ULSD compliant version is all that is being produced anyway so it probably doesn't matter. 25 vs. 31 gal dosing also probably doesn't matter since I doubt anyone is measuring and proportioning anywhere near that precisely.

Google is your friend. I also copied the PDF and uploaded it for
everyone to read and enjoy. < snicker >

I like the idea of having a pump system for auto dosing.
From what I have found some may think it's snake oil
but in using it in the past before I made some changed to
the tune I was running. I found that the soot on the EGR
valve was not near as nasty as when I was not running it.
So was it the way I was driving or the PM-22.

Also if you look at the part number is PM-22 and the extension #
is the size of the container it's in. See image below.

Well, the MSDS recommends nitrile gloves, so perhaps nitrile O rings will hold up. I'll give the pump idea a shot once I finish another project I'm working on. Just a simple 4oz stroke piston pump should be sufficient I'd think.

 

From my simple mind, the newer 6.7s had a 31 gallon tank as stock…I believe Ford was just making my math simple: 4 oz per full tank of fuel. I hated fractions.
