82612 Ethanol Stabilizer - 12-Ounce Bottle

In all reviewer honesty, it's difficult for me to ascertain how effective this product is. Years back, I'd dump STP products into my gas tank and not really know--or be able to tell--if the product was really doing anything, which ultimately lead me to stop throwing money at injector cleaners, etc. My car--a 2008 Mazda 3s--was running fine when I poured the contents of this ethanol stabilizer into it at a recent fill-up and it's still running fine. So, unfortunately, I'm not able to espouse the efficacy of the product with any conviction, only to say that my car's performance certainly has not suffered from using the stabilizer. I think, perhaps, that the product is best intended for use with gas-powered lawn equipment and such, where ethanol can corrode fittings and cause operability problems. Three stars doesn't ding the product, but merely indicates that its merits aren't immediately evident.

There's no reason I couldn't or wouldn't use this in my would-be daily driver, and in fact, I just might wind up making some use of it in same as that would-be daily driver winds up sitting more frequently during the part of the year when I would likely be riding my motorcycle on a more regular basis. With that said, some might question just what I requested this product for and where I would highly recommend using it. That's a very easy question to answer for me... small engine machines pretty much demand (e.g., this is a need, not a want, when using small engines) the use of a product such as this one to keep those engines from being damaged by the ethanol that is being added more and more frequently to the gasoline we purchase.With a gas powered lawn more, or in the case of my now less frequently ridden second motorcycle, the thought of leaving those machines sitting with ethanol in the tank is a definite concern. As that ethanol breaks down it can negatively impact the engines that it would be going through. Adding this stabilizer helps to prevent that breaking down process and should, in turn, help protect your engine(s) from potential damage.In the case of the family autos they are typically driven regularly enough to not really leave that much opportunity for the fuel to sit and break down. There's just a lot more turnover of the contents of the tanks in same, and in turn that seems to reduce the need for any treatment such as this, though if I were going to leave a vehicle sitting for a longer period I would certainly consider the use of this stabilizer (or other similar products if necessary).

We have an older John Deere riding mower and have to travel a good bit to find gas without ethanol in it. If we use gas that does have ethanol, it will run like crap and then just stop running. Using this stabilizer is the only way to be able to use gas that has ethanol and have the mower still run. It sucks having to transport a big riding mower to get cleaned/flushed/repaired. This little bottle eliminates the issue. I actually never thought of using something like this in our old (1996) suv, but I think I am going to give it a try and see if there is any noticeable improvements.

This is perfect for stabilizing our smaller tractor over periods where it may not get as much use. It is great workhorse but very old and needs all the help it can get to protect it.So we used half in the tractor. After this it gets a little tricky. I wanted to add this to our chainsaws but it took forever to figure out how much to use. I am not sure what incorrect use would do but I was pretty concerned about it. This bottle needs a better design so that it can more easily be used in rototillers and other small equipment.

As others have said, the instructions are terribly lacking. They say "Add entire contents to gasoline tank. Treats up to 20 gallons of gasoline." This is a great product if you have an older vehicle that is not designed to run on ethanol blends or if you have an automobile that does not get driven very often. Given the cost of this product of a little over $0.30/gal for a 20 gallon fill-up, it's probably cheaper than what you'd pay for filling up with ethanol-free gas, if you can find it at all.As for small engines, this is a different story. You definitely need something for small engines. Ethanol completely ruined my ATV fuel pump ($600!!!), so this is a small price to pay to protect against something like that. The problem is, how many tanks do you have that are anywhere close to 20 gallons? Not many, I'd guess. If you store 20 gallons, then this would be fine. Given that the instructions say to use the entire contents at once, I don't know how effective it would be to split the use of the bottle over time with several fill-ups. It may be that it loses its effectiveness after it's opened if it is not used quickly. The instructions really do not say if that is an option, so I would be inclined to try to use the entire bottle at once, if possible. The instructions do not say if it would be ok to use it to treat only five gallons or if over-treatment could cause damage.

Storing a mower or snow blower is usually handle with a bit of stupidity and a lot of the obvious: You run 'em until they run out of gas and, if you get it all out, they usually start. But MAYBE some of that gunk builds up and you'll have sputtering and/or a clog. Just in case you didn't know it, leave gas in a tank for too long and it gets sticky, then leaves a coating that can gum up the engine. Ethanol is the worst culprit of 'em all (after all, corn derivative, which is a skip away from corn syrup, which is sugar).Penray makes a tank stabilizer. One bottle into as much as 20 gallons keeps your small engine ready to rock when time is your enemy. Can you live without it? MAYbe. But Penray's is made to cu through it all, so for a few bucks, protect your machines and sleep better for it; I do.
