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.
