Customer Reviews

24 oz. Fuel Stabilizer is rated 4.9 out of 5 by 14.
Rated 5 out of 5 by from Time will tell This stuff is highly rated for what I'm trying to accomplish with it. I want to store plenty of straight 89 octane unleaded and unleaded/2-cycle mixes for an entire season for my string trimmer, chainsaw, blower, mower and gas-powered pressure washer without having to run to get fuel more often than I have to and to avoid water condensation in the fuel containers and the tanks on the machines. I've already used it in an older string trimmer and blower and it cleaned them up to the point that they run like when they were new. The carburetors must have been varnished and gummed up? I'll see how fresh the fuel remains over the next 8 months.

Rated 5 out of 5 by from Ethanol Shield This is a great product that is needed today due to the engine-harming amounts of ethanol being put in our gasoline. Many people are unaware of the damage ethanol does to engines. Home Depot only carries small bottles in the store and larger bottles must be special ordered. Larger bottles, including 32 oz. should be available in your stores. Home Depot should also promote the product. I have no business interest in Ethanol Shield...I'm a consumer of the product.

Rated 5 out of 5 by from Best stabilizer on the market I worked as a parts person in one of the largest Stihl dealers in the U.S. We researched all the products extensively and Ethanol Shield is the best on the market and is a necessity when running ethanol fuel in small equipment. I use it as a stabilizer in straight fuel as well as mixed fuel for 2 cycle engines. For equipment that won't start or runs rough, use Mechanic in a Bottle.

Rated 5 out of 5 by from Works great Worked great with no starting problems after storage. I don't know how much different it is from Stabil though. I would use again.
Date published: 2016-08-09
Rated 5 out of 5 by from From my experience, it works. When I buy gasoline, I add a dose of this and a double dose of Sta-bil fuel stabilizer. My understanding has been that Sta-bil prevents oxidation of fuel during storage and Ethanol Shield prevents damage related to ethanol. I cannot verify either of those claims, but what I can say is that I have stored 2-cycle mixes for my blower and trimmer and straight gasoline for my Honda mower for more than a year and even after that duration I've experienced no fuel related problems. My mower starts on the first or second pull and the 2-cycle motors all start and run as when the fuel was first mixed. I will say that I drain the fuel from my mower and trimmer for the winter months (I use the blower year round). Still, you cannot argue with 1 or 2 pull starts on year-old fuel. Which product is responsible for how much of this I cannot say for sure, but I will say that I have found a combination that works well so I'm sticking with it.
