15 parts per million ULSD

I thought that we could no longer get the 500 parts per million but its still out there does anyone else know whats going on out there?

After fixing all of these injectors, I have now discovered that for the most part I have been using the 500 parts. How I found out was I fueled and the sign was Giant 15 parts per million.

Than with in 15 minutes I noticed heavy smoke and a knocking or loud pinging noise. Called a friend of mine who explained the truck is starving from no Cetaine or Sulpher in the fuel. I purchased at the next truck stop some Lucas fuel treatment followed the instructions 1 gallon treats 400 gallons and spiked it just a tab, and put another 5 gallons in each tank to mix it up.

The truck ran terrible for the next 300 miles than added more fuel and the instructed amount for 35 gallons. Than she smoothed right out and the smoke disssipated as well. I continued only fueling for all last week at only 70 to 50 gallons at a time adding the Lucas.

Upon getting home I fueled up 171 gallons and I only had enough for 100 gallons and the problem came right back. I called the truck stop and asked them (171) fuel up and asked what the parts per million are 15. Thus my friend was correct, so my solution is to add the Lucas. What, why, or how this treatment does I cannot answer it, but the results are stunning. The engine is actually smoother than it has ever been, and fuel economy is up almost one mile per gallon. How can such a little bit be so effective?

Heard that some refineries in Texas were under exemption (don't know why), and are still being allowed to produce the <500 ppm LSD.

Someone needs to take the authorizing party to court to make a decision. Either the old fuel or the new. I'm guessing if we keep jumping back and forth, it'll cost us more burnt injectors. Who's going to take responsibility for that?

I have a 2005- ISC and I notice no difference in performance with either fuel. As far as fuel economy is concerned there are so many variables it is hard to tell whether mine burns off more of the 15 ppm to do the same work or not. However, if I was a betting man, I would say that I use more, let's say 8.5 with 15, and 8.75 with 500. I think it is still too early to tell- when it warms up and I can stay with 15 for a while, then we should be able to do some "controlled" experimentation. (Similar loads, terrain, low wind and warmer temps, no idling at all, steady speed of 62 avg, etc).
