So I just changed my oil today for the first time and decided to change my fuel at the same time. I bought the truck with 5k miles on it and now it has 7k. I got under the truck with a 16 oz water bottle and set on the frame with the tube in it and opened the valve on the fuel/water seperator and the bottle almost filled up with completely clear fluid. I emptied it, changed the filter and cranked it up and re-drained it and same thing. I repeated this (minus changing the filter) 3 times and the fuel remained clear. It smelled like diesel, was greasy on my hands like diesel and left a shiny coating on the grass I poured it on like diesel but it looked like water. Is this the ulsd? It always had a highlighter tinge to it before in the old truck. It runs perfect.

 

sorry i cant help all i know is that my fuel has high lighter tinge to it too

 

If there was any water in it, the water would pool on the bottom of the bottle. The truck wouldn't run if it had that much water in it.

 

Thats what i thought, just freaked me out a bit.

 

thats ULSD. . .while your filling up mext time look at the foam. . .if it's white you have ULSD, if it has a yellow tint to it you have LSD

 

How can that be? If someone is selling lsd arent they taking a huge risk? SOmeone on another forum said it could be no.1 diesel?

 

LSD is not good for the 07.5 6.7L's the 5.9's can burn it no problem, the problem comes in with the particulate filter and the sulfur content of the LSD.

#1 is kerosene

 

Thet can still sell lsd but it has to be labeled lsd not ulsd. I have caught myself a few times almost filling up with lsd.

 

and you can run it. . .it's just harder on the DPF since LSD is sootier(If thats a word).

 

So they can still sell lsd??? I thought it was basically outlawed. I dont pay attention except that the pump says "diesel" since it doesnt matter ulsd or lsd in my truck.
