Went to the Ford Dealer this morning to pick up a couple of bottles of PM 22 for my 2012 F-250 6.7L and the parts guy told me I can't use it in the 6.7L engine? Only for the 6.0 and 6.4.

Is he right?

I'm new to these trucks but that's the first time I've heard anyone say that.

 

Well I am surprised to see at the Ford site, it does not mention it's use in a 6.7.

Motorcraft® Brake & Engine Performance Fluid & Cleaners

•Note: This ultra-low sulfur formulation can be used in engines required to meet 2007 emissions requirements (e.g., Ford’s 6.4L diesel engine) and is backward compatible as well (i.e., can be used in Ford’s 6.9L, 7.3L and 6.0L diesel engines)


I can see why he might think so as Ford does not specifically state it is for 6.7 on that page. He may be reading too much into that though.

 

PM-22 and PM-23 are both listed in the 6.7L Diesel Supplement owners manual.

 

This info sheet on PM22 lists the 6.7, http://mobile.powerstrokediesel.com/...FuelDollar.pdf

 

I was gonna say... That part number is listed in my manual... Probably when the document he was reading was made the 6.7 wasn't out yet.

 

Field engineer's. Not only suggested using it but had the dealer give me some bottles. And that was on my 1st 2011.back in 3-2010.I have never missed giving it its recommended dose every fill.

 

I use it in mine all the time. My service manager advised me to be adamant about using it.

 

I guess my 6.7 is like a kid with candy about the PM-22, cause it sure craves it.

 

That is because of the kick back he gets for selling it...

 

My truck is new and on my first two fill-ups I was averaging 16.3mpg. I bought a gallon container of PM22 from Amazon, and on my last two tanks of fuel with PM22 I am averaging 1-2mpg better with a slightly heavy right foot. Driving conservatively I was getting up to 19.3mpg.

 

I think that one factor in how well PM22 (or any other additive) works is dependent on the fuel quality you get from the pump. Since diesel only needs to be 40 Cetane and Ford recommends 45. Any additive I would use would increase the Cetane and PM22 does.

I notice a difference in how the motor sounds/runs as well as the MPG. I get more of a traditional diesel sound when the fuel I put in is not high quality. Not obnoxious, just noticeable to me as no one in the vehicle ever notices when I ask.... Even though I typically add an additive at fill up time, sometimes I end up adding a little more in or if it continues to be noticeable I fill up early again. Since it is warm where I currently live, making the tank B20 also cures the sound and makes the truck run smoother, but you don't get better MPG running BioDiesel. I also get B99 from a supplier that turns over as much as he can get from the refinery so I am typically running 2 week old Bio when I do run it. I have not run it in a while and probably should as it helps clean out the DPF which is helpful for my city only driving.

I know where to get decent fuel locally, most of the time I run into this problem "on the road".

 

I've noticed pretty much the same results, except around here I don't know anyone selling diesel that isn't at least B-10 and many are B-20. I hate the stuff especially when their cetane level is low.

But that's why we got PM-22

 

They must be cutting bad diesel with biodiesel or using bad biodiesel. Biodiesel has a high cetane level.

 

B-20 is still mandated at 40 Cetane level. B-100 has a minimum of 47

You can tell which station is selling the good stuff within a few miles after filling up.
