STAR BRITE Star Tron Enzyme Fuel Treatment - Concentrated Formula 32 Fl. Oz. – Treats up to 512 Gallons - Fuel Stabilizer & Treatment, Gasoline Stabilizer, Star Tron Marine Enzyme Fuel Treatment

I have a 2008 Cadillac Escalade I started using this when I filled up after a 100 Miles, I noticed my car was idling and running so much better. This is a good product. I also use it in all my lawn mowers.

I have been using Stabil for years and thought I’d try this after reading all the reviews. I started with it on an old Poulan Pro 22” Lawnmower and after running a tank of treated gas through it ran a lot better. I moved up through chainsaws, weed eaters, pressure washers, generators, and finally my 2019 Subaru SUV. All ran better with the additive as I run 87 octane gas. I was most impressed with how it made my Subaru run like it had a tuneup done. Acceleration was better, MPG moved up from 27.9 to 28.9. That’s the best it’s ever been. I store about 20 gallons of Gas every Hurricane Season for my generator and treated it with this product last year 10/15/2024. Just tried some today 07/12/2025 in my generator and it fired right up and ran like it was new. Poured the other 15 gallons in my SUV and it runs great. Heading down to resupply my treated gas cans with fresh gas for the coming Season. I can recommend this product for your gas treatment.

I used this in my boat. It worked very well, the gas in it was at least two years old at the time. Started and ran very good.

I would like to start off with the Pros of this product - Has stopped the "ticking" sounds in my engine (do to the Ethanol gas). - Engine runs smoother, and acceleration has increased. - MPG has increased slightly. - Makes my lawn mower run smoother. - Make my trimmer run smoother. - It can be used in my car, lawn mower, and trimmer. Con: and the reason why I only gave it 4 starts - The bottle leaks every time you pour it. I have tried many different ways to put this product into my car without the bottle leaking (Measuring cup, funnel, eye dropper to measure the product out without having to pour from the bottle [which takes time]). However, no matter what I've tried, the bottle continues to leak. I am still looking to find other ways to retrieve the product from this bottle without having it leak. I know for some this may be a trivial thing, but it does get quite annoying when trying to figure out a way to measure the ounces that you need to put in your car without the bottle leaking. I will continue to use this product because it does work. I'll just need to find a better way to measure out the product without it leaking.

Have used for years, saves gobs o' $ compared to fuel system cleaning time/labor.

Noticable Improvement. Started adding this to the last tank of ethanol gasoline, as I'm switching to ethanol free fuel in my Chinese 50cc scooter. Marked Improvement within the first few days. Continuing Treatment, now that it's running ethanol free. Fantastic Morning Startup and Idle.

I first discovered Star Tron Enzyme Fuel Treatment on the shelf at a marine parts store many years ago. Unsatisfied with the performance of Sta-bil, I asked a store clerk what he recommended and he showed me Star Tron. He said it has an active enzyme that "eats away" at gunk and deposits in the fuel. I admit, I was skeptical, but I gave it a try. All I can say is wow! A decade later and this stuff has never let me down. What's so great about it? Whereas Sta-bil works great for fuel that may sit up to 8 months or so, I found that any fuel stored for a year or more would cause problems. I have a very efficient 3.5 hp outboard motor, a small push mower, and a garage-kept motorcycle that all tend to go a long, long time on a single tank of gas due to intermittent or highly seasonal use. Thus, it is not strange for either those engine tanks or my fuel storage containers to have fuel sit more than a year before being fully utilized. After repeated gumming problems with Sta-bil stabilized gas, I switched to Star Tron and ALL of my problems went away. In fact, I poured this stuff into the tank of my outboard which was becoming increasingly difficult to pull-start (the small fuel jets clog very easily) and a few days later, it resumed starting up like a new motor! Thus, I believe the claims that there is an active enzyme in Star Tron that eats away at deposits. This stuff doesn't just stabilize the fuel; it can help clear small partial clogs like I had in my outboard! After the success with my outboard in particular, I started putting it in my push mower, weed whip, and motorcycle. In all cases, it has worked like a charm with no adverse effects to performance. The gas just seems to stay fresh and keep the motors running efficiently, with no backfire problems, smoking, clogs, or other symptoms of fuel-degradation. I also like that you don't have to be very precise in the measurement. Overtreating the fuel does not seem to be a problem (except that you will go through a bottle quicker, of course... I do still try to mix approximately to the specified proportions; I just don't bother getting out a measuring cup to be exact). All in all, I'm totally confident in this stuff. It bears mentioning that I have never had trouble with ethanol in my outboard either. The Star Tron appears to discourage it from separating, as I've never had to flush out the tank--even after a year of no use--due to bad/separated fuel. Highly recommended!

Lo utilizo para 2 cuatrimotos y una planta de luz y hasta hora me funciona muy bien eh te ido hasta un año sin utilizar la plana de luz y la gasolina conserva sus propiedades

Tried it out on my generators ,quads outboards which many had fuel problems because of useless ethanol gas and all my poor running issues went away so going forward will definitely be using this product.

Con este producto pude pasar la verificación de mi vehículo, no he notado un aumento como tal en el rendimiento de la gasolina, pero con lo que he ahorrado en la parte mecánica esta mas que sobrado

Medio hasta 100km mas por tanque

I own a resort, and my marine mechanic strongly suggested I buy this product for my motorboats to perform well, and mitigate ethanol from gas. I now mix it in when filling my gerry can with gas so that all my outdoor maintenance equipment and boats have this stabilizer in it during cottage season, and extra over the winter season.
