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've found that this works even better than the much more expensive Octane Boosters that I've tried. Even though it's marketed as a fuel stabilizer, fuel treated with Star Brite StarTron feels like a much higher octane fuel. We can only get 91 octane pump gas in California, so I had been using octane boosters. The StarTron treated fuel was even better. No tendency to ping with the A/C on under heavy torque loads and with better mileage and no low RPM stumbling. A bargain as a few ounces treats an entire tank -- not like the multiple whole cans of expensive octane boosters.

This is some great stuff. My car was losing some of its gas mileage because the throttle bottle was getting carboned up. This cleaned it and my mileage has improved.

I use with Stable and don't have any issues even after months

Seems to enhance long term storage of fuel in autos I drive infrequently.

It help to clean up the fuel system good. Better gas mileage after I use it

Great stiff . I use the concentrated diesel additive in everything year round . Then twice a year or so I put Sea Foam a competitors product through too . Just was raised on that stuff but this works great . It is much cheaper because it takes so little . I get over 20 tanks out of each bottle plus all my small engine gas bought in cans are treated along with the boat , mower , ect . No problems . Always fill with fresh gas and run before storing things seasonally so the fresh gas gets in the carbs . Never have a problem when pulling out of storage . Your not suppose to but one time I stored a car five years and just put a few ounces in every year . I kept it on a battery tender and when it was time to use it ..it started right up and ran the tank out . Fresh gas was treated and put in and it ran just fine . Changed the fuel filter after a few tanks . This is good stuff . I doubt I have to use the Sea Foam at all but it is in my blood as it was all I used till I found this which costs so much less . Like I said about 28 fill ups per bottle for $25 where sea foam is $7 per fill . Figure it out yourself . This stuff works though I think the Sea Foam is a better pure system cleaner this prevents gunk and I do get about 1 mpg better so it pays for itself .

I was reading the reviews about one guy mentioned his daughter told him to put it in his wife van that he thought had transmission problems. He put this product in ,and the problem went away. That sold me. I purchased my first bottle after reading what he said on his review. I drive a 2007 Acura TL-Type-S.I have about 248,584 miles on it . I have use 93 octane since I bought the car in 2016 used. About 6 months in ago October 2022 I started using 87 non-ethanal that made a big difference, but I put 2 oz of this product in the engine I was blown away. My car was always fast . If I had this car new , I can imagine it would run like this. This product took it to another level. I was always looking for a mechanic to adjust my shift points on my transmission. Come to find out I don't need it. It runs like a new car. I am very pleased to have found this amazing product. I think it cleans everything that comes in contact with the in the fuel system. Incredible Product (PS) the gallon jug is a refill In case you'll did not know that. With so many saying it is hard to pour. Just saying.

Husband uses this all the time.
