I run Sta-Bil year around.

Would Recommend

10 years ago, when we moved from a condo into a house where I had to take care of the yard, I decided to always run Sta-Bil in all my power equipment. I add it to my fuel cans when I fill them. I've found it helps counteract the issues with 10% ethanol that is in regular pump gas. 2 1/2 years ago I was sidelined with some health issues. I finally can get back to taking care of the yard etc. My lawn tractor, pressure washer, push mower, 2 cycle string trimmer, 2 cycle blower and snow blower all h...

Ease of use!

Product works great!

Would Recommend

I have been using Stabil for quite a long time. My classic car fires right up after sitting all winter with this additive. I also use it in my generator, the tank is always full but rarely used, I trust Stabil to make sure it’s ready to go in case of an emergency.

Excellent product

Would Recommend

I have used Sta-bil for years and will never store any gas-powered engine without it. Whether it's my muscle car, lawn mower, chain saw or weedeater, every fuel tank gets the proper dose before storage and starts right up when needed. Highly recommended.

Reliable peace of mind

Would Recommend

In 2021, I purchased a generator to provide electricity during power outages. The outages can last days or just a few hours - a can of gas may last two years or more. I have now used STA-BIL in that gas can for two complete 2-year stretches, and, both times, the generator ran perfectly even at the two year old point. Reliable peace of mind. I label the gas can with the date I put new treated gas in it so there's no question how old it is.

Winter Storage

Would Recommend

I use Sta-Bil in all my gasoline engines. I never worry about the fuel going bad even after 6 months. I highly recommend Sta-Bil products.

Must have for gas powered motors

Would Recommend

I use Stabil for my limited use classic cars and my gas can for power lawn equipment. Pay little now to avoid lots of big problems later. Good stuff.

Protects my infrequently used machines

Would Recommend

Have used this for a couple of years for my collector cars and yard tools (Snow Blower and Pressure washer). No more carburetor flushes or replacements due to degrading gas. Everything starts on first try. Especually great for my collector cars that go months between startups.

Every Year since 2018

Would Recommend

Great product and highly recommended. Starts in the Spring time running excellent with zero issues. Sad to use it, but New England’s weather sucks.

Works Great!

Would Recommend

I've used Sta-Bil for years, for lawn mower/snow blower gas I have a 5/gallon gas can I'll put 2oz of Sta-Bil per gallon it'll take me 2 years to use up 5 gallons! I have another 5/gallon gas can for my backup generator I just use a double dose of 2oz of Sta-Bil for 2.5 gallons. After a year or so if I don't lose power, I'll put it in car and get another fresh can for backup!

Best for storms

Would Recommend

Don't be surprised by hurricane season and not have much left for a generator. Generator calls for stabil and have had ethanol free rec90 go bad in 6 months without it.
