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

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.

use it on my gas items (cars and weedeaters/leaf blowers) and my diesel items. One gallon bottle is the worst so buy something to use to mean fluid.

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 :).

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

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.

I used this product in combination with other fuel system water and treatment additives and the "cocktail" seems to have worked well for removing water and smoothing out my diesels idle. A+!

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.

50g diesel tank topped off and winterized each year with this stuff and I've never seen a drop in the Racor.
