I either use Diesel Kleen, or the stuff you get a Ford. I maybe up for a group buy deal. I use some in every tank so I am not really sure what it does from just running straight ULSD.

Logan, I have some in stock, If your Up this way I'll give you a few bottles for your opinion! I'd like to see some folks thoughts on this stuff, Also would like to see if anyone noticed mileage improvement!

Hey Gord,
I may have done that already!

(P.S. The two blonds didn't mind and the tube was filled with Michelob).

And then I woke up.

I use powerservice as its the only thing around my neck of the woods. I have seen lucas on the shelf, but thats it. I can only base my opinion on powerservice in the white bottle. No fuel problems at all this winter, and we seen a week of -10 to -30 temps. Im not sure on the milage, because I have been using it from the start. I add 10-12 ounces to 25-30 gals.

I use Stanadyne or Amsoil additives. I tend to favor the Stanadyne Performance One Shot bottles as ya just open and dump it in vs. measuring out the right amount in some other brands. Pay alittle more for that conveince but thats a personal choice. I really like the Amsoil Cold Flow Improver for the really colds days.

In a total of 1,000,000 + in my two 7.3s, driving in almost every state in this nation, I have never put anything in my fuel talk but fuel. Do what you want, but don't be scared by those that say that you need to put in X.

There may be something to that, but do bear in mind that the diesel fuel you use is quite possibly different from the fuel other people use where they live. Also, the new diesel formulations aren't the same as the diesel you've been using over that 1mil miles...

Plus, I don't care how many miles you have...when it's 15* out like it was this winter...you better be prepared.

My dealer recommended Diesel Kleen, thats what they use, so that's what I've been putting in my tank.
