I was just watching on TV last night a study on fuel additives and none of them did anything.

I used to run the motorcraft brand but I don't think it did anything. I just dont think putting 8oz. In 30 gallons is going to do anything.

I've been using Stanadyne in my truck for the last year or so and believe that it has helped. Boost's Cetane level, help's in fuel/water separation, and acts as a lubricator especially when running winter blend fuel. It's all on the web site. I'd recommend it, however please feel free to do whatever you feel is best for you $50K truck "An ounce of prevention...."

now I do believe in using something for anti gel in the winter but the rest of it is just snake oil just my opinion. I track my mileage meticulously and have never seen a difference using or not using nor have I ever noticed the truck running any different on or off the additive.

I have tried using Stanadyne, the Ford stuff and Diesel Kleen. Didn't notice much if any difference with the Stanadyne. I noticed my DPF cleaning was less frequent with the Ford product. I then started using Diesel Kleen and noticed even less frequent DPF cleaning. I did notice an improvement in fuel mileage. Maybe 1mpg. I was impressed and told a friend that has the same truck. He noticed an improvement in his truck. He was so impressed with it he started putting it in all his trucks and equipment. He is a small sitework contractor. I was recently talking to him and he decided to stop using it in is truck as a test and he immediately noticed an decrease in fuel economy. Needless to say he started using it again. Both truck are 2008' s and stock.

You definately need to tune/delete your truck.

10 doesn't seem right. I have gotten as much as 20mpg imperial which I believe is 17 us mpg. That is all highway driving and driving at 60mph. It is all hand calcualted. I have been keeping a fuel log for about 2 years. My truck is an 08 club cab with 20" wheels. I installed the 4" air dam on the truck and I noticed an increase of 1mpg. I also have a cap installed. I am not sure of the improvement this has made but I am sure it has helped.

I have used a fuel Additive from BG products, they make some of the best gasoline and diesel additives that improve deposit control. I have used this in my fuel every tank for 38k. It is very important in my opinion to lubricate the fuel system when using ULSD fuel. I also use their DOC oil conditioner in every oil change. Read up on it. bgprod.com
BG Diesel Fuel Lubricant with Conditioner
BG Diesel Fuel Lubricant with Conditioner is a superior multi-functional fuel supplement. It provides the necessary film strength and lubricity to low-sulfur and ultra-low sulfur diesel fuel to prevent fuel pump and injection parts from scoring and seizing. This diesel fuel additive complies with the Federal low-sulfur content requirements for use in diesel motor vehicles. It will remove deposits from the fuel system and prevent their re-forming. Two ounces (60 mL) of BG Diesel Fuel Lubricant with Conditioner treats up to 40 gallons (150 Liters) of diesel fuel. Catalytic converter and oxygen sensor safe.
Part No. 227D

I was wondering the same, so since I started using it Diesel Kleen, I figured I'd see what it does, if anything.

Here's some analysis of my hand-calc mpgs plotted against odometer since buying the truck new. Hey, I'm an engineer :)

Blue line is mpgs. If I eyeball a running average, looks like I get about 14.5mpg. Sharp upward spikes are straight 250mile++ freeway shots, station to station. Sharp drops are always due to long regens. Between 10K~15K, I had a couple of long trips down to LA but I was using truckstop fuel. See how mpgs suffered. The rest of the time, I used Shell or Chevron.

Brown line is a running concentration of DK in the tank starting from when I first started using it. Drops in concentration are the times I forgot or didn't have any DK to pour into the tank.

DK recommends 80oz/250gal = 0.3oz/gallon concentration. Looks like I'm averaging less than that, so I'm wondering if I'm not pouring in enough to do any good? It certainly didn't seem to help much when I was using truckstop fuel.

The engine does seem to run quieter when DK concentration is up. Regens 'seem' to be less frequent too. I added a 6th order polynomial trend line on the mpgs (there's no option for anything higher)...I don't see any strong correlation of using DK to any big increases in mpg, although it seems to be going up a bit. But that might also be attributed to my tires wearing down too.

I think fuel brand has more to do with mpgs than anything else. I'm using mostly Shell these days...I seem to get the best mpgs and the least regens with it. We've recently started getting summer fuel, so I do see an upward mpg trend...

I have been using opti lube and what a difference, after about a tank or two the injectors were noticably quieter and I had more power. Not sure if it helps mileage cause I dont check it but they claim 1 to two MPG I like how it takes care of injectors and boost power.

My truck likes DK the best out of the ones I have tried. Motorcraft/Amsoil/Styadyne.

Not worried about mileage increases with it. I run it with every fill up to add some lube to the ****ty ULSD fuel...

I've always used Fords additive and just switched to XDP's

XDP Diesel Power Plus Fuel Additive

The main reason is where I live the Octane is 40 out of the pump, I know the 6.4 is recommended to run 45 so I always use a cetane booster

I might try that Rev X , 6 point increase is nice

I run stanadyn in the winter in every tank of fuel. In the summer I will add stanadyn with bio diesel for one tank, then change my fuel filter. After I change the filter I will run one more tank of normal diesel with stanadyn to relube the system after the bio diesel has cleaned alot of the gunk out.
