new diesel fuel good or bad?

[F-350MAN]

Hey guys! I'm sure you've all heard about the new USLD fuel, does anyone know much about this stuff? or are we gonna get stiffed again by the EPA and end up screwing up our engines all I know is its low sulfur, or do we have to start adding stuff to our fuel and how is this gonna affect the older trucks(pre2006)

It defintely would be a good idea to run a lube additive with every tank as ULSD is pretty lacking in that department. They say their going to have lube additives mixed in but I don't trust the big oil companies to do that w/ the corners they cut already.

What kind of additive would you reccomend? I have heard of guys adding a quart of ATF to a tank for lubrication.
My fuel mileage dropped about 3 MPG (when burning diesel rather than vegi oil) and there are only two factors that I can think of that might be the reason. I added a airaid cold air intake and i started using ULSD - both about the same time. Which one of these factors most likely dropped my mileage?
I thought adding the intake would help milage but i haven't modified the exhaust yet so maybe not.

The ULSD probably was the culprit. The intake system wouldn't cause a drop unless your hammering on it alil more to listen to the turbo.

ATF is an old wives tale, still some guys that swear by it but there are better things out there. I personally run Standyne Performance Formula, there is also some stuff made by Gold Eagle, that is suppose to be pretty good stuff. I'd stay away from the Power Service stuff you can buy at Wal-Mart.

I drove through Salt Lake City last week and filled up with "ULSD". I was amazed at the loss of power. It wasn't a lot but enough to notice. The truck felt like it had a miss...or two. My milage also dipped about 2 mpg. About half way home I stopped at a Napa, picked up "BK" -I think- diesel additive. Regained the lost power and even increased my milage. It was $9 to treat 30 gallons. I saved that much on the milage increase alone.

I have also noticed a loss of power...wasn't sure at first but now it's definate. I guess I'll have to stock up on some additives.

fyi, I've had tremendous luck with Stanydyne Fuel Additive. my engine is quieter, starts easier, and I get a mile or two better economy per gallon. I also tried Amsoil and Power Service. They each DECREASED my fuel economy so I don't recommend them. with the price of fuel and benefits to your engine, it's worth the price ($3.00 per 30 gallons of diesel).
