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.
Yes, I would recommend this to a friend.

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 !

Living at 7500 feet in the mountains requires winterizing the motorcycles and dune buggies. Once I started using the Amsoil gas stabilizer startup in the spring with the snow melts is no problem. I've used other brands that keep the gas smelling good but when it comes to starting, well often it's not that quick. With the Amsoil stabilizer, the bikes start right up even after sitting for several months.
Have used this product in cars which it in storage for months at a time. Since switching, I have never had any issues with varnish or sludge. Even the finicky floats on a Rochester carb work after extended periods of no use.
