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.

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 :).

The best diesel additives around buy this all the time for my boat diesel.

It works as good as the gasoline version, which is really good.

Star Tron has always produced a great product. Only issue with this order was that the cap worked loose and some liquid leaked out, causing a hazardous/flammable material spill. Only a couple of ounces leaked out, but that's enough to treat 40 gallons. Suggest sender ensure cap is on tight and possibly even do a seal over the cap to ensure it doesn't come loose.

Knocked out the water/bio problem I had with my diesel tank. I used much more than they suggest, because at low amounts it had less than favorable results, but using half the bottle for a 60 gallon tank was a silver bullet. No problems since.

I absolutely love this stuff!I use it in every gasoline motor we have. Cars, 2-cycle boat motors and all the yard equipment. I talked to the chemist, not the sales guys. He said although they always work hard to make the best product they can sometimes things go better than you expect as happened with Startron. It does everything. Brings oxygen to the point of ignition, burns cleaner, more power and even clears away and prevents carbon build-up in the cylinders. I found out about it when they started adding ethanol to the gasoline in Ontario Canada where we spend our Summers at the family cottage on a lake. Our 2-cycle boat motors absolutely hated ethanol. I got stranded in the middle of the lake several times. So, it was imperative I find a solution. Startron totally solved the issues. I also use their Starbrite EZ to Store, EZ to Start Gas Storage Additive. The instructions are to put it in the last tank of the season and run the motor to coat the internal parts for a long Winter storage. I found that using both products all the time made our slightly cantankerous 2-cycle boat motors always start first or second pull, without fail. The guys at Starbrite say all of them use both products all year long in everything as well. I use both products in everything all the time, not just the boat motors. Highly recommended.
