it's in TDR issue #55

I haven't used any additives since reading the article and haven't noticed any difference in performance. I like all the information on the TDR site, but I also listen to what everyone here and on the DTR say. Everyone's truck is different (mods or stock). I am in a real learning stage right now. I've been around diesel tractors for years, this is my first diesel truck (always had gassers in past). No one can say for sure exactly what effect the new ULSD has on any of our engines, so for now I will listen to what everyone has to say and just try to do the right thing (for my truck).

That's kinda where I'm at as well.

 

Sulfer is NOT a lubricant. The process of removing sulfer from the fuel depletes the lube from diesel fuel. There are standards for lube and all kinds of other standards that on the road fuel has to meet. Diesel, gas, and other refinery products ALL come through the same pipe lines and ALL have there additives put in at the distributors location. All the brands draw off the same pipe line and then carry the product to their distribution point. That is where Amoco, or Exxon, or Shell become branded by adding their own proprietary additive package. Additives that we add at the pumpare not a need, they are a want.

 

I didn't read the TDR article but I did find this: http://www.frontiernet.net/~mopar197..._cycle_oil.htm don't know if it helps or not.

 

That MOPAR mans site is pretty cool !!

 

I am no petro-chemist but my guess would be that the additive causes the fuel to create a finer mist with smaller droplets when injected into the engine thus giving a smoother, more controlled, burn and therefore making it "knock" less.

 

There are several components inadditives that cause the engine to run smoother. One isCetane, which produces an even burn of the fuel. When the new ULSD came out, we learned that the new fuel didn't have the same lubrication properties as the old stuff. Not because of sulfer, but the process that removes the sulfer also removes the lubricating properties. I have tried different additives, and found the Stanadyne USLD works for me. Adding more than what is recommended doesn't do anything. I've checked the injectors after running 1/3 more than what was recommended. No clogging. Not running an additive seems to give me more lifter and injector pump noise- verified with a scope. I am guessing this is due to the lack of lubrication which may be wearing out my engine faster. It also misses about every 3 or 4 seconds due to the lack of Cetane. I figure everybody on here has done their own tests and knows what works best for them. Theseare just my simple observations. I'll attempt to attach a link with more info.

I took this from your link and it raised a new question in me. How / WHAT are they doing in Europe? Are they adding additives?



The move to lower sulfur content is expected to allow the application of newer emissions control technologies that should substantially lower emissions of noxious particulates from diesel engines, similar to changes that previously took place in the European Union. New emissions standards will apply in some states beginning in 2007.
