Cetane boost safe?
I have a 2011 F-250 with the 6.7L diesel. I was wondering about adding one of the cetane boosting and lubricating addititives. I don't particularly "need" it around here in CA since it doesn't get very cold, but thought it might be a good idea anyway. But I don't want to screw up the engine by adding weird gunk that might throw it off. Is it safe to use one of the common additives?
Also, if I wanted to store 5 gal of diesel in a jerrycan, is there any kind of fuel stabilizer to add? I've added the red fuel stabilizer to gas in a can, but I haven't seen anything specifically made for diesel. Would adding cetane to stored diesel help keep it from gelling up and keep moisture out?

I'm using 4oz of the Motorcraft Cetane Booster (PM-22-A) every other tank.
I use it to help the fuel system work a little more efficiently.
I figure it's better than not at all.
I did use one bottle every tank once and I don't notice an increase in MPG or any other amazing advantage.

Be very careful about jerry cans
Many steel jerry cans are plated with zinc (galvanized) to prevent rust. This zinc can dissolve into the diesel fuel and ruin your injectors. The plastic jerry cans are safe as are some polished stainless or aluminum that are now hard to find.

There are several other posts about additives just do a search and you should find plenty of information.

There are two types of additives out there. One containing an anti gel agent to prevent diesel fuel gelling at low temps, the other does not contain it. Power Service has them in a gray (without anti gel) and white (with anti gel) bottle. Both of these contain cetane boost and lubricity agents. Unless you are in the cold mountains in California, the one without ant gel will work. Check the bottles, I'm color blind (joking) and may have mixed up the bottle color.
I believe there is a benefit from at least the lubricating agent and obviously the ant-gel agent.
As for storage, i don't store it, so I have no advice on it.

I've used the Motorcraft Cetane Booster in my 2006 F-350 and will continue to do so in the new 2011 F-450. I keep several empty cetane booster bottle and when I buy a new bottle, I divide it up into the empty bottle so I have a 25 gallon dose in each bottle.
I didn't notice much difference running solo, but it made a big difference when I latched onto the 18K fifth wheel. Made enough extra power that it eliminated a lot of the transmission hunting on small, rolling grades on the freeway.

STA-BIL is the stuff to prolong fuel life. There is a model made specific for diesel. As stated by others only use approved plastic to store fuel in and never metal. With the HP Systems in the 6.7 you dont want to muck it up $$$$$$$$
The question of additives more depends on the quality of the fuel you are using. If the vendor spec matches the spec by Ford then no additive should be required. Why spend the $'s if you dont have to. For example if your vendor's cetane is consistant and rated at say 48 I wouldnt add any. If not consistant or high enough then uplift as needed. I did use the Ford Cetane boost in the winter but we get to -30C here. I only use Shell VPower which has a cetane boost in it and is winter conditioned. I dont think there is a set rule for what to use and from who. It depends on the condition and quality of fuel you are trying to accomdate for if that makes sense.

I also use a Sta-Bil bottle to dispense the power service. The 80oz PS bottle is very messy when trying to pour it in the tank. The Sta-Bil bottle has a 1oz (good for each 3 gallons of diesel) mark and is essentially spill proof. The 32oz bottle, wrapped in a towel, fits nicely behind the back seat.

My first bottle of PS white bottle, was messy as heck. Glad it only lasted three tankfuls. I kept the empty bottle and use it now to just pour in enuf for one treatment at a time. Only have to tip a partial bottle instead of a full one and don't have to quit pouring to see how much more to add.
I will probably go to the gray bottle now that it's warming up.
I hate to get that stuff on my truck.
It cleans off real well if you get it right away. The first time I used it, I didn't notice I spilled on the paint. Couple days later I see this streak going down the paint and I thot it was the tech at the dealer when he added my def. Distinctive odor quickly let me know it was I that goofed. It took a lot of elbow grease to get that stuff off. You get that cetane on your hands and it takes two days to get rid of the smell.

I use the Powerservice stuff in every tank... silver (DieselKleen) in warmer months and white bottle in cold weather. It also goes into my wife's Jetta TDI (150,000 miles and not a single problem with the fuel system and runs like new)
I fill a small stainless water bottle (using a funnel) from the big jug and keep it in the truck, so it's easy to pour into the tank when I need it. For longer trips (multiple fill ups), I use some clean plastic juice bottles that I have and fill several of them with the correct amount so I don't have to deal with the messy jug while on the road.

Cetane rating is basically a scale to describe how quickly and efficiently the fuel combusts after injection. The higher the number, the better the fuel burns.
If you are worried about too high of a cetane rating, don't be. Similar to octane rating for gassers, the engine has to be designed to benefit from a higher rated fuel. But unique to diesel, a cetane rating over 55 does nothing.
If your engine calls for a cetane rating of 48 you can run 40 without issue. But the engine performance will improve as you move towards 48. Past 48 you won't see any benefits.
