I added it to my GTO after sitting 5 months while replacing the engine. I haven’t had any problems with start-up or fuel related issues.

The best stabilizer I’ve used

Used it for off season storage and throughout the year. No issues with fuel spoiling.

I use this year round in my boat and generator always cranks up easy and runs great

I use this in my vehicles and everything else with a gasoline engine. It keeps fuel from going bad and and your motors from rusting from the inside out. I rely on the Amsoil reputation.

Very good, especially for small engines. Saves a lot of $ at repair shop.

1954 Chevy car. In the fall, as winter approaches, I put the prescribed amount of stabilizer in the gas at each fill. Never know when the last drive of the year will be before the salt is off the roads in the spring.

Added on all my vehicles this fall and hopefully the vehicles that storage half a year will do fine. Thank you!

Nothing significantly changed over the course of several months of use in multiple vehicles , conveyances as far as the stability of gasoline used. Nothing significantly improved

This is by far the best formulation of a gasoline stabilizer available anywhere. It definitely does what it’s supposed to and outperforms all others that I’ve tried. You truly can have piece of mind when using this. I use it in all of my landscaping equipment.

Been using this in my 10kw Honda generator along with non-ethanol unleaded fuel. My generator finally runs without any weather-related issues. So far it’s been working excellent!!!

Use it in all my engines before storing it for winter or long periods between use.

I use this in all of my engines so they are not rusting from the inside out. I mostly like this product because I have a car that I put only a couple of thousand miles per year on and I don't want the gas to go bad or develop a rusty gas tank caused by water separation in the fuel.

I put it in at the end of this season

Winterize my toys with it have been using it for years.

With winter coming I plan on using this more through the temperature swings we see here on the Mid-Atlantic coast. Will edit review in spring or next bottle whichever is first.

works as advertised

First time use of product I been impressed with your products since my recent change done in laconia by Adam

Great for Gas or Diesel motors helps fight fuel Deterioration.I Use this when storing Equipment for winter time. Helps fight Gun and varnish also.

I use Amsoil stabilizer in everything. I use it for all my power equipment.when I fill up my 5 gallon can I add stabilizer to It.gas today does not last but Amsoil stabilizer makes my equipment fire right up even after sitting all winter. you can't go wrong with this product.
