Star Tron Enzyme Fuel Treatment Concentrate – Rejuvenate & Stabilize Old Gasoline, Cure Ethanol Problems, Improve MPG, Reduce Emissions

Love this stuff! You cannot over do this stuff when adding to the gas tank or can. My machines all start with no problem after sitting for months. No known carburetor issues to this point after 5 years of use.

based off the reviews and the instructions this should be good. would greatly benifit if it had a better way of measuring it out. going by "cap fulls" is such a waste and causes spillage.

Great product have been using it for years. Would highly recommend. Will not purchase anything else.

This works very well on carb engines to prevent ethanol from corroding the internals.

Great value 16 oz! If you store anything that uses gas it will keep the fuel fresh!

Used it in the past, but I have not used this yet

Keeps gas fresh

Good Stuff

Helps all machines start

I have a lot of winter equipment. Snowmobiles, snowblowers, plow trucks, and so on. The gas left untreated during summer storage will destroy carbs and leave fuel systems a mess. I tried this against original Stabil and Seafoam. The Stabil failed completely and I had a mess in my carbs and fuel systems. The Sea Foam worked in the carbs but the gas was kind of skunky the next fall, so I ended up flushing out the fuel systems. Startron left the carbs clean and the gas smelling like I bought it today. Now I use it in every can of gas that I buy so that I know that I won't have problems. I also tried a little in the car's gas tank. It seemed to run a lot better and have more power, but until it gets tested further that is anecdotal only. *In fairness I have to say that I used the original Stabil not any of the newer products like the Marine or the 360. I don't know how those work. I am thrilled with Startron so I am sticking with that.
