What part of the world are you in?
I use Diesel Kleen. There is a summer and a winter formula. It will boost the cetane rating of the pump fuel to where it should be in your truck. The winter formula will help keep your fuel from gelling if it gets cold where you are.
I also use ashless 2 cycle oil. The process that removes sulfur from ULSD also reduces lubricity. The oil helps keep the injectors lubed.

I use stanadyne fuel additive for the fuel as well as 4 oz of 2 cycle synthetic engine oil per fill up. I fill up my 2002 f350 when it gets to about a quarter of a tank. It tells you on the stanadyne bottle how much to add.

Im in Texas and all I use is the grey bottle diesel kleen. Winters arent enough to gel my fuel. And how much is up to you. Neighbor drives big rigs for a living, and his own mechanic, and sid you can throw anentire bottle in and it wont hurt. Me I buy the 100 gallon one, and split it between 2 fill ups. I use about every 3-4 tanks.

I use the ford additive every tank....7 bucks a bottle at the dealership and I haven't had a bottle leak. I have used most available....diesel kleen, standadyne, lucas etc and have never noticed any difference between the brands. A 7 dollar bottle of ford additive will last me 3 tanks with a 38 gallon tank.
I am closeing in on 400K miles with my original injectors and attribute their long happy life to the consistant use of a lubrication additive to the fuel and regular oil changes.

Clem...
Motorbug got basically no fuel additive for the first 388k of her life.
She had 3 injectors needlessly changed out due to a dip something shop mech getting a ghost cct from 1,3, and 8. I only recently started experimenting with additives and found my truck likes lucas, and ezoil the best... but i really only see about 1mpg improvement at very best with no other real signs of improvement.
Dunno... maybe its more hype than anything?
Tell ya this...
It dont take much gasoline running thru injectors to kill them.

400K miles on one set of sticks! Wouldnt that be nice? On the other hand, I find myself wanted them to die so I can upgrade!
I've only recently begun adding ashless 2 cycle oil from WM, to counter the low lubricity of ULSD, but Tugly tells me a little biodiesel is being added to fuel in some areas already to combat that. I need to look at the station pump next time and see what is included.
I based this decision in part on this link showing some testing that was done to compare additives:
https://www.ford-trucks.com/forums/1...l-in-fuel.html
It's cheap enough by the gallon at WM. I put it in 20oz dr pepper bottles and put it behind the seat. Add one bottle each 1/2 tank or so (about 1oz/gal).
I did it to try to extend the life of my injectors and quiet them down, along with running synthetic, hutch mod, pre-pump quick disconnect delete and FRx.
I'm still on the fence on whether a cetane boost is necessary.

I have not done the hutch/harpoon, HPX or FRX just a small in line pre filter before the pump and quick connect delete at around 110K miles.
I am getting ready to change injectors in the next month or so because the idle is starting to get a little lopey and she (Jenni) romps at anything below 30* initial cold start. If I don't use the fuel additive cold start is much harsher and the romps last longer. My fuel mileage is still 18ish 60/40 city/highway as it has always been... hand calculated most tanks for the last 8 years.

I use the dosage specified on the DK bottle. You can use more, but you won't see any benefit. A motor designed to run on fuel with a cetane rating of 45-50 will not run any different on a fuel with a cetane rating of 60. It is similar to octane rated fuels in gassers. The motor has to be designed to run the fuel.
The ashless 2 cycle oil is cheap, engineered to burn clean, and available at any Walmart in big a** jugs. I use about a quart per 30 gallons. I don't do it every time, but most of the time.

When I filled up today, I looked over the station pump to see what was in the diesel #2 I was pumping in. Unfortunately, no info was posted on percentage of biodiesel or cetane rating. Where does one get that info for a given location in this country?

I had a discussion with a station manager last week about bio. The sticker on the pump says it is a bio blend, but it doesn't say what ratio. I told him that some of the newer trucks can have their warranty voided if they run anything over B10, so it was important to have that posted. He has no clue.
