Star Tron Super Concentrated Diesel Formula - Enzyme Fuel Treatment for Enhanced Engine Performance - 1 Oz Treats 32 Gallons - Stabilize & Rejuvenate Diesel, Biodiesel & All Regular Gasoline

Very pleased . We learned this can be used in all engines it does not hurt to put more in any of them so we use this more concentrated formula in the gas engines 1 oz and follow the instructions for the diesels . You must be patient and you will see it will boost performance and overtime clean the engine improving mileage about 5% though it takes a few months to get there . You can use this in all your motors it will save you money as it is twice as concentrated as the gas or even more then the small engine variety .This will stabilize fuel over the winter so you do not need stabil . I do run sea foam once in a while too in my vehicles but its not needed this is amazing that so little can actually help . This will freshen fuel so often after storing fuel for a year or more I add a little more to those tanks of fuel stored for the generators or emergencies that were not used and then run it in the car . Of course I fill the tank with fresh stuff . This works and is the most affordable additive on the market , so much so I was skeptical at first . Not any longer .

The unique product for DIESEL FUEL seems legit in what it claims to do. The additive is designed to lengthen the storage time of your Diesel fuel and to aid the Diesel engine performance.Family and Friends have recommended this product to me and I have yet to fully test this but, trust that the spectacular claims are true.

Immediate increase in power & clean burn lending to soot reduction on only 1 ounce to 35 gals. Priceless!!

Using on my old farm tractor. Hard to tell if it is working yet. At least it should extend the life of the engine.

I use Star Tron as my fuel stabilizer. I've used the other common alternatives but like Star Tron the most. I can't give you an objective, scientific reason why and there's plenty of debate online about the different brands but I can tell you I've never had an issue with any of my 4 stroke equipment treated with this. Some equipment sits unused for a year and it always starts right up and runs great. I use premixed cans of ethanol-free 2 stroke gas, like TruFuel et al, for that type of equipment. One year, I used my own 2 stroke mix that wasn't treated with a stabilizer. I knew it was dumb to let that crud sit in there for over a year. When I went to finally started up my Stihl chainsaw, it now bogs and needs a carb clean. I also let old, untreated gas sit in a Honda snowblower which began running rough. I'm going to run a tank of treated gas through it and will report back on the outcome.The diesel version has more additives than the regular gas version, and came recommended online. You won't go wrong with this. Do yourself a favor and treat all your gas. You'll save yourself a lot of hassle down the road. Trying to clean a carb the lazy way - by not tearing it down and simply trying to clear the issue out with additives - typically doesn't work that well.

This was a godsend. Our diesel pickup truck started lurching and was not running well. My husband does all our mechanical work, and he ran tests on the truck, fixed several things, and that particular problem persisted. Eventually he narrowed it down to a turbo problem - the exhaust brake was sticking, causing it to lunge and brake, lunge and brake, repeatedly - and this was something he couldn't fix at home. Estimates for repair in the shops ranged close to a couple thousand dollars. Then he read online that sometimes this treatment would actually clean the gunk that was making it stick inside, so we figured it was worth a try before spending a big chunk of our retirement money on mechanical work. Voila! It worked! What a huge relief! Truck has run perfectly again ever since.

2022 F350 Super Duty Dually. Purchased for the sole purpose of preserving diesel fuel in my gravity feed tank in bed of truck as I buy in bulk and often do not use the bed tank fuel unless prices jump or I am pulling my RV. I poured the recommended amount (1st time use) into the onboard tank and took off for a weekend drip of 8 hours round trip. My engine seemed to quite down a bit. Fuel economy was pushing about 2 and sometimes 3 mpg better than I normally get. 2 to 3 mpg over distance sure adds up quickly. I have since run two more tanks on this product and still getting better fuel economy. I am sold that it works. I suggest start with the small bottle to see what it does for you. Keep the small bottle cause you will buy the large "gallon" size and portion it out :).

Works to keep diesel fuel fresh. I use it in my truck and tractor.

No issues with bug in the fuel so I have to assume it’s working. I top up the tank with this every fill and filters have remained clean
