A couple of things. First, there is no algae, they are living microorganisms. Both MD and JF work to breakdown sludge and particulates which does include microbial contaminants. On the Biobor MD spec sheet located at https://www.biobor.com/Biobor-Resources/spec-sheets/SPEC-BioborMD.pdf it specifically states, "Sludge dispersants break up and dissolve fuel sediment sludge into small enough particles that will pass harmlessly through filters and injectors, enabling your fuel system to operate at peak efficiency with properly atomized fuel spray. BioborMD® cleans fuel systems to allows the engine to produce its designed optimum horsepower and torque, further increasing economy." Biobor JF, while not a sludge dispersant, it does breakdown microbial biomass or biosludge. Biomass is made up of microorganisms and their acidic byproducts. When Biobor JF kills the microbes, the biomass breaks apart, some of which is dissolved, some of which is captured by your filter if the biomass is in large quantity. As far as lubricity, if you use Biobor JF, there is no reason to use another lubricity additive. Biobor JF adds lubricity, exceeding the ASTM standard for engine efficiency, adding protection to your engine. See the Biobor JF spec sheet at https://www.biobor.com/Biobor-Resources/spec-sheets/SPEC-BioborJF-NEW.pdf . Hope this helps. Thanks for the comments and questions.

Scotty Hutto, you can use Biobor MD and JF together. Also there is no need for any additional lubricity additives. MD contains a lubricity additive and JF by its very Boron based chemistry is a lubricity additive as well as a biocide. Biobor JF was originally invented in the early 1960's to reduce knock in gasoline engines. SOHIO (Standard Oil of Ohio) used it in all of their premium gasoline. Eventually they created the Boron branded gasoline stations. It was later found that Biobor JF sterilized the fuel systems in the premium tanks including the fuel terminals and fuel delivery systems. The problems with corrosion caused by microbial contamination was an industry disaster. The premium tanks treated with Biobor never had any of those issues. That is where the aviation industry became interested and the rest is history. Now Biobor JF is the premiere fuel biocide in the world and the only one approved and currently available for commercial aviation. Hammonds dedicates enormous resources to make certain that all of the products it manufacturers do what they claim to do and are the best in the industry. Biobor Catalog - Industrial.pdf

The shock dose should always be used unless you are using biocide in every drop of fuel. The maintenance dose is for all fuel all the time, not the periodic treatment of fuel. Unfortunately, Startron does not digest the bugs or the biomass. It contains a small amount of dispersant which helps but will not digest anything. It is a basic fuel enhancement additive. It will not clean the fuel. Biobor offers Biobor MD. It is a little more expensive but does more than Star Tron. Because of its proprietary blend, it reduces soot up to 94% for cleaner combustion, increases cetane by 6 points for increased efficiency, disperses and breaks down sludge, lowers pour point for better flow, inhibits corrosion, adds lubricity and controls water. I attached a spec sheet. Give it a try. We have a number of very large fleets using it in all of their fuel and they have seen reduced maintenance costs across the board - enough to pay for the additive itself. Check out www.biobor.com and look at the other products as well. No matter what enhancement additive you choose to use, Biobor JF biocide is compatible and recommended by all of the equipment manufacturers. In the most critical applications, aviation fuel, Biobor JF is the only approved fuel biocide available. Hope this helps. SPEC-BioborMD.pdf

Actually Biobor JF helps to break up and dissolve the microbial contamination. When microbes infest a tank, they will eventually form biomass layers consisting of enzymes and acids. The biomass has to be broken apart and physically cleaned. This is what typically clogs the filter after treatment. Unlike dead microbes, the biomass needs to be removed not reintroduced through an additive by some method of dissolving and burned by the engine. Any dissolved biomass will damage the fuel system including the injectors. The newer the equipment, the more sensitive they are to any form of contamination including dissolved solids like biomass. Also, just as an aside the growth is not algae. The growth in the tank is microbial consisting of bacteria, fungi and mold that feeds on the fuel. If the fuel is heavily contaminated, the tank should be physically cleaned. Mild to moderate contamination can be dealt with through the use of Biobor JF fuel biocide.
