STA-BIL 22275 32 Ounces Ethanol Treatment

I have been using STA-BiL for almost 2 decades, I always put a little bit more to treat the gas, no issue with gas that I got in the fall, and using now in late spring. I usually don't use gas longer than 6 months — old gas go into my car. No issue with clogged carburetor in my snowblower, lawnmower, hedger and string trimer. i empty the tank as much as i can for the snowblower and don't fire it up till a year later. No rust in the gas tank either. Good insurance to have against needless repairs and tinkering.

Seems to be working but there is no visible proof

Great product , all Indian petrol old car owners should use this , I recommend to use it every full tank , I started pouring Jio petrol with this product and got increase in my mileage from 12 - 13.2 , 10% increase , mostly covered the cost of this product and also greatly increased the life of my petrol tank and all internal components.

Item seems to be good just started using delivery very much before time

Maybe I'm OCD, but I want to add the additive into the gas tank BEFORE pumping in the gas, to make sure the additive mixes into the gas. If you need 1 ounce of STA-BIL for every 5 gallons of gas, then you're going to have to know how many gallons of gas you're going to pump so you can calculate how many ounces of STA-BIL to put in the tank, first. It's a bit of an imposition. I let the tank drop to just below 1/2, and then pump 10 gallons. But first, I add 2 oz of STA-BIL. Or if the tank has a bit more than half, I'll predict on pumping 7.5 gallons, and put in 1 1/2 oz of STA-BIL, first. Works for me, your gas gauge may vary. First time I've ever used this kind of dispenser. It's easy to use, except you'll need a little light, and possibly reading-glasses, to see the markings on the bottle. There are markings for 1/4 oz, 1/2 oz, 3/4 oz, and 1 oz, if I recall correctly. And I figure a little more than the instructed ratio is better than not-enough, if you're going to err. I read an ethanol protectant is beneficial for older engines like a 1999 4 cylinder Toyota engine with 103k miles, that the older the engine the more prone they are to ethanol damage, and that ethanol protectant can reverse some damage -- whatever that means. Maybe it just dissolves away existing corrosion and then it continues to protect against more corrosion occurring. Maybe the gas companies should put ethanol protectant in the gas with the other additives so we don't have to perform this exercise.
