I've never worried much about the biocides or what grows in my fuel. I guess I use it up pretty fast. It's never been a problem for me.I have been using some additives to add lubrication to my fuel. The 6.7L Ford fuel pump is very sensitive to not getting lubricated and tales of $12,000 repair bills from pump failures have been seen on the internet.I look at Lubrication, and bumping my Cetane rating as the two main things I expect from any lubricate. In the winter months I also seek an anti-gel since I park outside and we can see 0° for a week or two in the winter.

I have been using Lucas or Stanadyne. Stanadyne also makes a winter formula that I have used when traveling North. At home I bounce between the Lucas and the regular Stanadyne and have a Ford 7.3 with 235,00 and a Peterbilt with 254,000 miles

Paul, Have you seen anything newer than this report? It was done in 2007 just as the new fuel requirements were changing what fuel we could buy, And I suspect also what fuel suppliments we could buy.I've used the Opti-Lube and am happy to support them as they are Utah company and I'm for supporting local small business. But I just wonder how valid it is 6 years after it was published. Have any of the other products improved their formulas and how about the new products that are now on the market that were not included in the test in 2007, like the Motorcraft PM-22.And while Opti-Lube was one of the better products in this review, It's still not easy to buy. Requiring either online or calling a phone number to order and waiting it to ship. While there are other products that I can go into almost any Farm Supply Store, Truck Stop, Walmart or auto parts supply and buy and use immediately.

Introduction of ULSD caused the study...and since I've upgraded to new diesels, I just ASSUMED... that the new diesels have been designed with ULSD in mind......so like I stated above I intermittently use the Stanadyne product...since Duramax says I really do NOT need any additives...

Most people will never know if they need the additives or not. Short of testing the fuel we buy each fill up. The additives address a broad spectrum of issues. Lubricity, Cetane, Anti-Gel, Biocides, to name just a couple.It is general stated that most diesel fuels in the United States are about 40-42 Cetane rated. I have no idea if that is true, since I have no way of testing it. If I remember right, I think my Ford manual recommended 46. But it would take me a few minutes to find that reference. So I usually add some additive to bump the cetane.There was some pretty heated discussions a year or two ago. The Bosch fuel pump that is in use on the current Ford and Duramax engines is lubricated by the fuel. If the fuel lacks in lubrication it can cause that high pressure fuel pump to fail. On the Fords it's a $12,000 bill to repair and replace the fuel system. With the passage of a couple years of production and use, we have not seen a rash of failures. For me it was cheap insurance to add a additive to improve the lubrication, Which is what was discussed in the article you posted.My third reason, was winter use of my vehicles. My trucks and equipment are parked outside. When I go out to start them, they will be at what ever the outside air temps are. And once or twice, I've had to throw concrete blankets over a skid loader and put a propane heater underneath to heat the equipment for an hour to warm it enough to get it started. Even having the equipment plugged it where it kept the coolant warmer did not help with cold fuel in the tank and lines. So using a Anti-Gel in the cold months is something I am interested in.

I run a 2008 Duramax and the injectors were relaced by Chevy at 55,000 miles. They claim it was because of the required bio in the fuel - I live in Minnesota. They stated that I should use an additive. Supposely GM additive is the same as Stanadyne Preformance hence have used since. Currently have 80,000 miles on the truck.

I don't use any fuel additives in my 2011 Duramax. I figure it's only something to clog the DPF that much sooner, so it will regen more often using more DEF and more fuel creating more soot and.......

No reason to run anything if you get good quality diesel. Only time you may need something is for the anti-gel additive. A good water separator and 2micron filter are all you need on a common rail diesel. These systems do not live long with poorly filtered fuel that are contaminated with water. As to the issue with Ford, they were late to the party. It's been a common thing on CR diesels such as the Cummins and Duramax. Fill up at the local Mom and Pop and take your chances. I fill up at high volume stations where trucks come in several times a day with fuel.

I work for a fuel storage terminaling & pipeline company & we store all blends of gasoline, diesel, jet fuels, etc. By law, we have to add a lubricity additive to all the ULSD fuels before it gets transported to fueling stations for automotive use. This is due to the low sulfur restrictions that became effective in 2006 since that sulfur was acting as the lubricity component. I've been told by many of our terminal mgrs that adding a lubricity additive to our vehicle fuel tanks is not really necessary since the lubricity additive is added to the USLD at the terminaling sites.

Forgot to add that's why I stopped using a lubricity additive in my Jetta TDI & Dodge Cummins. I do like to use the Sea Foam maybe once/twice a year though...

I guess I've been lucky. My first diesel was a 96 F-350 with the turbo-diesel (1 year before they became Powerstrokes) and never put an additive in it. Bought fuel at reputable suppliers and kept the filters changed. It had 385K on it when my son totaled it and had NEVER had anything done to the engine. Had the POS tranny out three times though. I have been treating the 02 I have now the same way. Anybody think I'm looking for trouble? It has 135K on it know and haven't had any trouble with. ( insert noise of wooden coffee table being knocked on solidly)

This subject has been discussed, and much cussed, over on the Cummins diesel site. The thought as I understand it is; using a bit of Wallyworld 2 stroke outboard oil in the fuel gives it enough lubricity, and won't hurt the DEF systems, or the catalytics. You do have to be sure and get the TC-w3 LOW ash, and add about 2OZ per gallon. I have about 190,000 Miles on my 2005 Dodge 5.9, and she has always been really good this way. Some folks have had some issues with injector tips coking up, but just running the truck with about 12,000 lbs up some hills, and heating the EGR's to about 1100F for about 10 minutes, blows that out. As I understand it,ALL the newer Diesels can stand to have a bit of extra lube in their fuels. Strange thing is; if you run B-20 Biodiesel, the lubricity is already high, and nothing is needed. Of course your lines, and tank will be de-gunked, and all that crud goes into the fuel filter, which means more frequent cleaning. Also, Biodiesel is much more hydrophillic, so stores more water...and that's BAD!

2001 F350 with the 7.3. I have been using the Ford Cetane Booster and Performance Improver. I found when using it I get an extra mile per gallon. Does it do anything else? Not sure, don't think it is hurting....... http://www.amazonsupply.com/ford-pm-22-a-compliant-performance-impr...
