Customer Ratings & Reviews

I use this in all my seasonal gasoline engined vehicles year round as it keeps carbs, fuel injection parts free from varnish build up in fuel systems when they are laid up for a season. None of them have failed to successfully restart even if the have been laid up for a year or more, also without the surging effects (carb. or fuel injection) that can sometimes plague a seasonal vehicle.

Have been using the stabilizer for 6-7 years now in all gas powered engines and never had a problem with this product. I feel secure that my equipment is getting the protection I want.

This stuff works, I'll continue to use it in anything i store.

We have a 2017 Toyota 86 Limited Edition with 8000 miles and it sits in our garage 95% of its life. We bought it new and only drive it a few times every year. We needed a good fuel stabilizer and this one has proven that it works! I would recommend getting this one.

With the ethanol in the gasoline especially with small engines this is the ticket especially when it sits for awhile this product will most definitely help

Another great product from Amsoil!

Use it for vehicle & small engine storage.

Usine amsoil gaz stabiliser will keep your whole fuel system clean and free of varnish for an easy start when your riding season will begin. Another very important point; Amsoil is the only company that the stabiliser will last up to ONE year!!!! Really good advantage for a snowmobile per example as they rest for 8 month. As all Amsoil products: NOTHING ELSE goes into my 9 engines and components. Thanks to products engineering and all staff, fast delivery without mistakes.

Put in tank and let it sit for the coldest part of North Texas winter. This is a few months. Good price would recommend to anyone wanting to winterize their bike.

If it's like the rest of their products then it's goood stuff

à l'automne lors du remisage des outils motorisés, ce produit permet un redémarrage sans faille au printemps!

I used this product for storage of my summer equipment stabilizer for the gas

Works great to keeps fuel good all winter

Yes, it works though I haven’t left fuel in storage for over 6 months.

Amsoil fuel stabilizer does the trick for my electric home generator. Despite infrequent use, the fuel stabilizer allows me to fire the generator up immediately when needed and ensures uninterrupted functionality when needed most.

Excellent gasoline stabilizer.

It was our first time using this product so i will let you know later how it worked for us.

Good stabilizer for our ethanol blended fuels can't complain

I use it all year long, every time I need gas I use it, never have any trouble starting my equipment, even thru storage for winter.

Does well.
