I alternate between a couple of fuel additives. I have herd of people running ATF in their fuel for lubrication , but then again I've heard ATF will gum up injectors... is this true.

Also I'd just like to say this is a great site. I think its awsome to see people helping other people and showing off pics of their nice trucks too.

 

Do not use ATF fluid. Modern ATF fluids contain friction modifiers that can wreck havoc on the pump and injectors. Just use a diesel fuel additive.

Yea Jake,
Exactly what Mikey said, ATF is a big no-no in diesel fuel. I'm currently using Power Service Diesel Kleen and Cetane boost that you can get at your local Walmart for around $5.00 for a bottle. I have used Stanadyne Performance Formula in the past on my older trucks and really liked it. I have just started using the Power Service stuff andtime will tell if I like the Power Service stuff over the Stanadyne stuff. The only reason I am running the Power Service stuff is because it's easier for me to get. If I don't like the Power Service stuff. I will be changing back to the Stanadyne. Good luck !

I have been useing the stanadyne PF formula since day one in my 2004 305/555 motor.No one here locally in S.Michigan carries stanadyne,I have to order it from Indiana (scheids diesel).Good stuff IMHO.coobie

 

Coobie, and how much water do you find in the fuel from your fuel filter cannister each time you change the filter?

 

I would be interested in expanding the question. Who has run an additive like Stanadyne or others and have fuel economy numbers both with additives and without additives?

 

Lightman,I have found none.I change mine every 5,000 miles with the oil and filter.coobie

 

I just started adding 16oz of Power Service Diesel Kleen & Cetane booster to each tank now, so we'll see if that ups my milage or not. I guess it'll be kind of hard to tell though, since my engine isn't fully broken in yet and am getting about 0.5mpg better on each tank already. But for less than $3 per tank, I'm gonna keep adding it. It can't hurt, right?

 

Schaeffers makes an excellent additive (schaefferoil.com) better lubrication than any additive out on the market. 1 gallon of the winter blend will treat 1000 gallons

 

Thats what I have been using since I have bought my truck, I use it about every 3 tanks. It works great, I have less noise at an Idel then other's.

It also seems to run better when I use it. Scheffer's will stand behind there products as well. One guy I know that uses Schaeffer's has had no problems or lift pump problems on his truck, He usally trades his trucks in when he hits 600k, That has really sold me on it.

 

I know we hashed this over before, but I thought I'd do an update.
After using straight PS and seeing little change in mpg, I went to ps and mmo mix and saw about 2 mpg increase, but the mixing is a pain in the ***, so I tried straight mmo, with little or no increase.
This trip we started with no additives and ran about 11.3 (13000lb 5er) , about 150 mi., after fuel stop and adding straight lucas additive, mileage went up to 13.3, next 150 mi.
Interesting.

 

I would not be using ATF. But I have heard of 2 cycle oil being used for lubrication.

I get Power Service at the cheveron card lock, same place I pickup delo 400 oil.

 

I usually fill up when the tank takes only about 20 - 24 gals. I add 12 oz PS and 4 oz MMO.

 

I'm surprised no one has tried to used wd40 in their tank, the non aerosol bottles sure would pour right in there, but to any benefit? half a joke half curiosity.
