Diesel Fuel Additives

Since the mandatory ULSD, seems like I have been getting worse mileage in my truck. I use Marvels Mystery Oil in my Toyota. Has any one used thier diesel additive? or are you using some other brand?
 
We've been using http://www.milliganbiotech.com/products/Milligans_Diesel_Fuel_Conditioner/ for quite a number of years now with good success. Being in the repair business, we've seen a number of Bosch rotary pumps fail since the ULSD showed up. In the same equipment, the guys running the lubricity additive haven't had any issues. I'm not going to make any wild claims on increased mileage, but we have seen an increase.

read the lubricity study on dieselplace.com as listed above. Milligan's product didn't fair too good.

I'm in the process of reading it now. 2 threads, umpteen pages each. I take sites like that with a grain of salt. Way too many guys that run a diesel pickup and believe it makes them a worldly expert on them.

I've got documentation sitting infront of me now that paints a completely different picture. Independent testing that is showing completely different numbers. (with the Milligan DFC)

One perfect example is the CDC 8.3L diesels in the CaseIH combines 1991 till near present. Even before the drop to ULSD, they would begin to run sluggish, "hunt" on the governor, etc. Guys would immediately change fuel, air filters with no change. The whole problem is lack of lubrication in the fuel. Always with guys that aren't pre-treating their bulk tanks. I tell them to double treat that tank of fuel in the combine and guarantee them it will clear up within an hour, maximum. 99.9% of the time, that's the problem. I'll sell guys fuel filters until I'm out (hey, I'll take anyone's money), but if that's not the problem, no one is happy. Real world experience on this end.

my 2 cents
 
I use the Amsoil Diesel fuel concentrate in the summer and Cold weather treatment in the winter, straight #2 all winter. This year they have the concentrate and cold weather wrapped up in one bottle.

Here's a report I found on Superdutydiesel.com.


These results are listed in the order of performance in the HFRR test. The baseline fuel used in every test started at an HFRR score of 636. The score shown is the tested HFRR score of the baseline fuel/additive blend.
Also included is the wear scar improvement provided by the additive as well as other claimed benefits of the additive. Each additive is also categorized as a Multi-purpose additive, Multi-purpose + anti-gel, Lubricity only, non-conventional, or as an additive capable of treating both gasoline and diesel fuel.
As a convenience to the reader there is also information on price per treated tank of diesel fuel (using a 26 gallon tank), and dosage per 26 gallon tank provided as “ounces of additive per 26 gallon tank”.

CONCLUSIONS:

Products 1 through 4 were able to improve the unadditized fuel to an HFRR score of 460 or better. This meets the most strict requirements requested by the Engine Manufacturers Association.
Products 1 through 9 were able to improve the unadditized fuel to an HFRR score of 520 or better, meeting the U.S. diesel fuel requirements for maximum wear scar in a commercially available diesel fuel.
Products 16 through 19 were found to cause the fuel/additive blend to perform worse than the baseline fuel. The cause for this is speculative. This is not unprecedented in HFRR testing and can be caused by alcohol or other components in the additives. Further investigation into the possibilities behind these poor results will investigated.
Any additive testing within +/- 20 microns of the baseline fuel could be considered to have no significant change. The repeatability of this test allows for a +/- 20 micron variability to be considered insignificant.
 
bio works really well, I have tried the following:
-Stanadyne (my favorite but hardest to find)
-Amsoil Cetane boost and Lubrucation
-Powerservice (easy to find... walmart)

I liked Stanadyne the best.
