Star Tron Enzyme Diesel Fuel Treatment - Super Concentrated Formula

Our old JD Tractor sat for about five years and when we started it ran like crap then we added Star Tron, shook the machine to mix the star tron and diesel and let it work overnight and the next day we cleaned the fuel filter and it ran great and I can attest that the Gasoline Formula is just as good especially for rejuvenating old gas. It's a great Fuel Stabilizer too.

Used product for winterizing the 50 gallon tank of diesel on a sailboat for Chicago winters. Every year we consume 15-50 gallons over the season, then top off in the fall, add this treatment, and put her on the dry.In 35 years we've had no water contamination. We even ran the tank dry one busy season and didn't get a drop in the racor filter. So I feel safe saying it works for water disbursement.Less importantly, I like the super concentrate so i can put one little bottle on the boat and be good for many seasons.

Just started using, so no performance opinion yet.Highly recommended by a couple of different large and small engine mechanics.WAY, WAY cheaper than other similar gas treatment products. Amazon price beat local store prices.Mostly concerned about protecting my small engines. Using only ethanol free gas in them, ... with treatment. Will better judge after a full season's use.

This is the first time using the star trine for diesel I’ve been using the gas one for yearsSeems like it works as well as the gas one

Did not help solve the fuel issue I had so I can't really tell if it did much. It did eat a little of the algae build up I could see on the edge of my tank fuel line, so it seems to eat some of the growth. Just can't say positively or negatively what it exactly did.
