Saves you money
No more dead gas after a couple of months. For fuel storage this is the answer. Over the winter (4 months at most) the gas is still useable. If you use fuel quickly use Mechanic In A Bottle. It keeps gaskets, seal, all carb parts clean and pliable.

Gas Stabilizer and keeping the rubber materials pliable.
This works to preserve all the gaskets, rubber materials and provides excellent gas stability. Buy with confidence!!! You should also buy the 1oz pump. It just makes life easier.

Works for water problems from Ethanol fuels.
Much better product than Stabil. Converts water in fuel and solubilizes for better combustion.

Hope in a bottle!
Just received it a couple days ago. Read the directions on the container but that's about all I have had time to do. I'm sure it has to be a good item with some of your advertisers swearing by it. I've also use Mechanic in a Bottle with some satisfying results. I haven't had much luck with seafoam and various other name brand items. If it works like I hope it does, I will be a lifelong user.

Remove water in gasoline
I love 62 miles out in the Atlantic Ocean. 83% humidity almost year round. Water vapor condenses in gasoline containers and equipment gas tanks. Ethanol Shield combines with accumulating water in gas tank.

No more water
I was suggested that I use Ethanol Shield. I even tested it myself. It does get rid of the water… unlike the competitors And everything started up first pull with the Ethanol Shield sitting all winter.. I can’t wait until spring comes!
