Some while ago there was a discussion about running additives in the older diesel engines while using the new low sulphur fuel. I have been an advocate of using additives for many years.
Recently in the forum "Tractor by Net", was a very informative study about the testing of various additives, and the resulting benefits. I found out that when my favourite additive was combined with the new fuel, it actually degraded the lubricity. For those that are again interested in these results, I recommend you check it out.

Gard, What about Lucas Oil? Does it fall in to the 2=cy oil classification? We have tried adding aceotone to fuel with no MPG differences. Have family members that use that in their gasoline vehicles and DO get better gas mileage. Just did not work on diesel.

I'm not a chemical engineer, and have to depend a lot of what I use, on what I can research. The only reference I could find about Lucas products being tested was:
14)Lucas Upper Cylinder Lubricant Gas or diesel HFRR 641, 5 microns worse than baseline (statistically insignificant change) 427:1 ratio 7.8 oz/tank $2.65/tank
Based on only that result, I would say that it did not improve the lubricating qualities of the diesel fuel, and therefore should not offer additional mileage based on its lubricity properties.

From personal experience the lucas oil fuel additive adds 1-3mpg for both my wifes truck Gas, and mine Diesel. It lubricates the upper cylinders, and I know over the road truckers that always put it in. I will add that different states have more and less sulfur in the fuels which makes a difference.

I also get an increase in mileage with Luca in my diesel and also when changing the oil in my truck the old oil gets dumped in to the fuel tank at the farm which also helps in the older diesels

The Ultra Low Sulfur standard says the max is 15 ppm of sulfur in the diesel fuel. My neighbor who the president of an Oil Pipeline says his refinery produces a 0-1 ppm product, and from what he tells me that is true of most of the refineries that were retrofited in 2006 to produce the new ddiesel. So yes your statement that sulfur will vary by state could be true, But I suggest that the difference between 1 ppm and 15 ppm is insignificant. Now if you could go back 15 years and buy the old regular diesel that was 1500 to 2000 ppm. Then your suggestion would make a difference.
But driving across state lines and buying Ultra Low Sulfur diesel will have virtually no difference in the lubricity qualities. You will see more difference in lubricating properties between brands of fuel as Chevron ,Texico, Phillips and other develope and add their own lubricity additive mixes.
