Great product. I've used this for many years and the gasoline is always ready to use.

I use Gasoline Stabilizor in alll my 4-stroke lawn equipment. The product seems to work well as I have yet to have a fuel related problem since first using a year and a half ago. Gave it 4 stars simply because the bottle design makes it impossible to pour small quantities without spilling or having the stabilizer run down the side of the bottle. The bottle shape is great for pouring into a car fuel tank but I see the primary use of this product in small, 5 gallon or less applications. Which Amsoil would offer a different bottle design. A great start would be something similar to the Sta-bil bottle; where you can meassure and pour small amounts directly from the bottle.

I store 30 gallons of fuel for my generator. I rotate 10 gallons every 30 days, so my oldest fuel is 90 days old. I have not done a placebo test with out stabilizer, but the gasoline treated with Amsoil stabilizer works flawlessly.

I use this product in every small engine, tool as well as my plow truck, 4-wheeler, and side-by-side and boats. It far exceeds any other stabilizer I have used, and I think I have tried them all. This product is so good - every piece of equipment I own starts at the beginning of every season, just like I ran it the day before!

The reason why I am not going to purshas this product again is because of the lack of directions pertaining to the amount of liquid to use per gallon of gasoline.

Great Product to use for any time length in out of operation power equipment. I use it in all of my lawn mowers, snow blowers, yard tractor and motorcycles. With the amount of changing fuel mixes and alcohol in gasoline here it helps to keep the fuel in a steady mix without the separation common here after short times. Almost always, my power equipment, will start with one, two, or three pulls, even after sitting idle for 3-5 months. The equipment will run normally. I will usually add some into my gas cans with each fill.

I trust Amsoil products, after using them for so many years. Our gasoline gets delivered by barge and then trucked to us. It's always got visible crud in it and I have to put it through a filter first. As soon as I get my gasoline, I filter it and add Amsoil Gasoline Stabilizer. While others in the area have had numerous problems with 'bad gas,' my gasoline has never let me down. It gets used in my Stihl saws, Echo yard equipment, my Polaris Ranger, my portable Honda generator, my Ariens wood splitter, etc. Never a problem.

Living in Washington State, I don't ride my 2014 BMW R1200RT-LC year round so I leave it in the garage hooked up to a Battery Tender, and the gas tank filled with Pure Gas AND 3 oz. of Amsoil's Gasoline Stabilizer. Every summer when I start up my bike there is little hesitation, and the engine settles down to a steady idle. Riding that first tank shows no problems or misses in any RPM range, though I don't get the full mileage of 300 miles, but with the very next tank of gas things are back to normal.

I recommend AMSOIL p.I. cleaner to anyone to clean the engine combustion chamber and fuel injectors or carburetor of a gasoline engine. I've used this exact product on a recommended vehicle maintenance schedule for many years. There is a very noticeable difference to prevent engine from knocking by cleaning the carbon from the combustion chamber. I use this in a Ford truck, Pontiac car and a Kawasaki motorcycle. Highly recommended above any product of its kind is AMSOIL p.I.

Before I started using this product (P.I.) my 2006 Toyota Tacome was getting about 19 - 20 MPG. When I use this product it moves easily to 20-22 MPH. It must be doing something good. However, I must admit to using exclusively Amsoil Signature oil.
