Ratings & Reviews+

STA-BIL® Fuel Stabilizer is rated 4.6 out of 5 by 35.
Rated 2 out of 5 by from Great product but priced too high I've used Sta-Bil for years with excellent results. I've found the product to be great, but charging this amount is unacceptable. I have since located the same 32oz. product elsewhere at a price much lower.

Rated 5 out of 5 by from Winter Protection This is one product that never fails to work. More people realize now that a lot of gasoline will gum up if it sets for some time. I use the additive year round. Those pesky leaf blowers will run like new with the additive in the gas.

Rated 5 out of 5 by from Sta-bil keeps your gas stable! I've used this product for decades to keep my small engine fuel supply from spoiling during storage. Even in the summer when the mowers use gasoline quickly, I refill my containers with the specified dosage so that the fuel systems are thoroughly covered. Gas stored over the winter for the snow blower & generator are still usable for the mowers if it isn't needed. Because I have consistently used Sta-Bil, I have never had a hard start problem due to spoiled fuel. Even my emergency chain saw starts quickly, & it's the leased used of any of my small engines. Do I recommend Sta-Bil? I certainly do! Even if you forget to put it into the empty gas can before filling, you can add it on top & still get the benefit. It will disperse through the gas on its own & blend as the liquid is agitated during refueling.

Rated 5 out of 5 by from Great Price for this Must Have Gasoline Stabilizer We live in a rural area and use a lot gasoline powered equipment for maintaining our property. So, storing gas is a must and using STA-BIL has proven effective for our needs.
