I suppose if it was left in an open container in the cup holder it could be a problem.

I keep it in the original bottle behind the back seat and never smell it. Only time I smell it is while dispensing into the tank. Wipe it clean with a rag before placing it back behind the seat.

It's more hazardous stepping outside at a gas station to fuel up than it is to travel with a bottle of pm-22 in the cab.

 

This. I'm not worried about it. The Amazon bottles I use don't leak any odor. Wipe clean and done.

I work around drilling rigs for a living. This is near the bottom of my safety concerns.

 

Everyone needs to make their own risk decisions, but I certainly disagree with the statement above. Could you share your reasoning for this claim? Many have had leaks from their PM22a bottles, so it's certainly possible to expose the occupants in the cab with vapor from this additive, and that exposure may be prolonged. A couple of the chemicals in PM22a are quite hazardous, especially the 1,2,4-Trimethylbenzene.

From the NIH site regarding 1,2,4-Trimethylbenzene

H332: Harmful if inhaled [Warning Acute toxicity, inhalation]

H335: May cause respiratory irritation [Warning Specific target organ toxicity, single exposure; Respiratory tract irritation]

Please reconsider making an authoritative claim that PM22a is safe to have in a small enclosed occupied space for long periods of time.

 

I will agree pm-22 contains hazardous chemicals as does diesel fuel and gasoline and every other can in the paint isle at Lowe's. However sealed in its container it's safe. The point at which pm-22 is the most hazardous is pouring it in the tank.

By your reasoning it should be hazardous to your health to walk down the paint isle at Lowe's.

That little cardboard disk we all worry about dropping in the fuel tank seals the harmful chemicals inside the container.

 

I agree with Deuce and dirthawg. I would think one would smell it long before it became a problem. But that's just MHO. But what do I know? I'm no expert.

 

If you have a 65 gallon fuel tank, then you don't have to worry about some of the storage issues when using Stanadyne products. I just dump the full bottle into the tank and toss away the old bottle.

When I used PM-22, It was an issue and I used some old .5L pop bottles to measure it out into the quantity needed per tank fill. Once dumped into the tank, I could toss the bottles used to store the PM-22. As mentioned above, the soda pop companies do know how to make a bottle that reseals ok.

I have a deep tool box and store all chemicals in it. I can carry enough additives for a trip cross country.

 

For the record, if I had a toolbox and I do want one, I would store that stuff in it. The cab is not my first choice. If I had a tonneau cover, I would store it under there as well.

 

I tried storing my opened bottles in an ammo can in the bed. Someone stole the ammo can.

 

Well I'm an xsmoker, my sense of smell is shot, I really don't smell the stuff. It's in a sealed medical glass bottle. What concerned me about the statement was if the PM-22A got to a certain temperature would it blow up. I do try to keep the inside of my truck cool. I have a cap and usually open the back window when I park; also have a moonroof and open the back of it but it does get warm in there.

 

To add additives or not to add additives?

I was once an additive fan (somewhat).

A Master Mechanic on large (Semi-Tractor) Cummins told me in person, no (unless you have a problem). If there is a problem, then get it fixed so you won't need additives.

Does anyone have a statement from a motor design engineer (Ford, Cummins, etc) that recommends additives?

Too many ppl get suckered into product additives that only do damage.

I do not use additives and have not for 20 years. If Ford knew you must use additives, they would give you a bottle when you bought it.

Owner's Manual:
Do not use alcohol based additives to correct fuel gelling.
Note:Your warranty will not cover damage caused by using an improper type of fuel or fuel additive.
Do not use alcohol-based additives to improve cetane quality, to prevent fuel gelling or any other use.

It should not be necessary to add any aftermarket additives to your fuel if you use a high quality diesel fuel that conforms to ASTM industry specifications. Aftermarket additives can damage the fuel injector system or engine. Use Motorcraft® cetane booster or an equivalent cetane booster additive if you suspect fuel has low cetane. Use Motorcraft® anti-gel & performance improver or an equivalent additive if there is fuel gelling.

Noteo not use stop leak pellets, cooling system sealants, or additives as they can cause damage to the engine cooling or heating systems. This damage would not be covered under your vehicle’s warranty.

Do not add extra inhibitors or additives to the coolant. These can be harmful and compromise the corrosion protection of the engine coolant.

Additives and Chemicals This owner's manual and the Ford Workshop Manual list the recommended additives and chemicals for your vehicle. We do not recommend using chemicals or additives not approved by us as part of your vehicle’s normal maintenance. Please consult your warranty information.

There are a few additives like for your coolant that are required, but these are not after-market stuff.

 

In regards to the statement “if ford knew they needed an additive they’d give one to you when you bought it” my dealership that I’ve bought two 6.7’s through, (my 2011 (sold) and the 2014) did give me a bottle of Cetane improver and fords winter anti gel. How does one suspect Cetane level to be low? It’s kind of a blanket statement from Ford. Don’t use additives, unless they’re ours, then it’s ok.

 

There's a guy on the other forum, and probably this one too, who has replaced and rebuilt HPFPs several times. He's seen inside pumps with and without additives and recommends the additives.

 

I suggest you do some research on the Bosch HPFP and how today's diesel fuel and it's lack of lubricity causes them to fail. Then you can make an informed decision

 

20 years ago additives were not necessary. Since 2007 or so when sulfur was taken out of diesel fuel, the lubrication properties of the fuel declined since sulfur is a natural lubricant. The CP4 pump needs lubrication or it will grenade and cost the owner 10k+ to replace the entire fuel system.

Have read of the PDF containing internal emails from Ford engineers. I believe it is linked in the CP4 class action lawsuit thread here in the 6.7 forum.

 

Sounds like your Cummins mechanic is old and not up to date.
