Customer Ratings & Reviews

I add this to the fuel in our Motorhome that sits parked about half of each year, with a full 55 gal tank. The end result is no issues whatsoever when we take it on trips! The AMSOIL Stabilizer keeps the fuel protected and road ready!

Works great UTV's Ben setting over a year and started right and ran great, Stabilizer worked really good

I use this in my gas cans and sxs for winter storage. Seems to work great.

Preserves gas fuel better than other products I have used. Used in conjunction with Performance Improver produces fuel quality and performance. Highly recommend!

I have motorcycles and a car that must wait for spring. Therefore gas stabilizer is a must every fall. I used to use Sea Foam until I saw the lab report comparing Sea Foam to Amsoil gas stab. The Amsoil is so much superior I bought a case. Now I am set for years.

We use this every fall in our air cooled VW's, Model "A"s and old motorcycles . Every spring not a single carburetor problem. With other brands we would have stuck needle valves on the carburetor floats.

This product is not for your everyday vehicle. This is used when you want to store equipment. It keeps the gasoline fresh.

Been using this product for a few years now works very well.

This stabilizer works great.

With winter coming it is time to out away boats and vintage cars. A great stabilizer to reduce varnish buildup from oxidation. Engines startup right away the next spring

Great product will buy again.

Avec ce traitement mes petits équipements repartent comme si l'hiver n'était jamais arrivé!!

Works great,I have a few 5 gallon cans I rotate out.

Good service! Great product

Been using product for a while. Have never had a problem with short term storage. If I know it is going to be long term I drain fuel from unit. But know incontinence have a problem with short term storage with this product

I'd used a competitor's product in past years and still had carb plugging after winter storage. Not so with Amsoil's product. I notice that small engines, be they 2 or 4 stroke, start easier year around when I add this product to my cans of gas.

Awesome brought the power back

I started using this stabilizer one month ago in the storage tank for all of my lawn equipment; tractor mower & two hand-held trimmers. I'll let you know if the gasoline makes it through this winter in usable condition.

Vehicles start in the spring after storage without ill affect. As to other benefits, have not done a tear down to perform an analysis for any definitive results.

This is my second purchase. I use AMSOIL Gas Stabilizer when I put up my 4 wheeler and 4 stroke boat motor for the winter - everything was right on in the Spring. I akso use it when I store my snowmoble in the Spring.
