If you live in NYC or in any major urban area that is car unfriendly, Gasoline Stabilizer is a must. I mix with Upper Cylinder Lubricant with no problems.

Have not used the product long enough to no if it is good

Use it and you will see the difference

Amsoil has always been great to use

I use this stuff in all my small engine machines when stored for long periods of time and never have an issue starting after storage

Only started using it

I am now retired so I don't drive as much as I used to so it is very important for me to keep the fuels in my vehicles and equipment fresh and that is exactly why I use this stabilizer. No longer have to worry about it going bad.

Goes in every can of small engine gas. Never had a problem even the following year. Keeps The fuel system cleaner than other stabilizers I have tried.

Good stablelizer

I own 17 old cars and trucks and have experimented with many fuel stabilizers including Stabil and Seafoam. Gas here in CA goes bad quickly and I can't drive them all. Stabil simply attracts moisture to it and makes it combustible and provides 2-3 months of protection. Seafoam seems to do less for stabilization and more for fuel system cleaning. Then I saw the corrosion it promotes in the tests. The Amsoil stabilizer is cost effective and seems to actually prevent phase separation. 12 months is no joke. I've gone longer and no varnish smell in gas or problem cold starting a car that's been sitting. I give this Amsoil product the same trust as all the other auto fluids I use. Thank you Amsoil for doing your homework.

Had cans of gas last more than a year with this stabilizer with no loss in performance.

This product is a "must have" in my 2 outboard motors, generator, pressure washer and all of my other gasoline storage cans used by both 2 and 4 cycle motors. This Gas Stabilizer will not cause any 'unseen" small rubber hose deterioration, as all of the Stabilizers on the market seem to do PLUS it keeps my stored gasoline fresh and completely useable for over a year.. Again something most other stabilizers on the market struggle with.. WHY take a chance... use the best !

Works great!!

This is a terrific product and I make sure to use it when putting the Snowmobile and ATV away for the season. Helps with start up and maintaining the fuel in the machines.

I use Gasoline Fuel Stabilizer in everything that uses fuel that sets for any length of time with good results. I have never had any issues with any gas powered engines fuel injected and carbureted.

Have always used Stabil and decided to give this stuff a try. It has proven to be my new go to and the price has been something a live with.
