Features
- INCREASES FUEL ECONOMY : Fuel Ox Marine contains a patented combustion catalyst that provides a more complete combustion. This allows for more productive burn of fuel.
- PROTECTS AGAINST ETHANOL : Fuel Ox Marine coats fuel tank and system to prevent corrosion from ethanol found in gasoline.
- REMOVES WATER : Fuel Ox Marine is a demulsifier for the water that is in fuel. It will separate the water suspended in gas or diesel and filter out through your boat's or watercraft's racors, separators, or filters. It prevents water from passing through engine and significantly slows the process of phase separation.
- 1OZ TREATS UP TO 80 GALLONS OF GAS OR DIESEL : Fuel Ox Marine has a highly concentrated formula that treats both gas or diesel for a small and convenient inventory.

For many years I always used Yamaha Ring Free and Startron at every fill up. Purchased a small bottle of Marine Fuel OX to try this year. Wow it works better than expected, my mpg increased by 1/2 mile per gallon ( when you get 1 mpg ) that's an increase, engine runs smoother and cleaner and increase top end. Used as directed at each fill up and noticed the difference only after a few trips. just ordered a bottle for next year.

I bought this for my boat, but tried it out in my truck first after reading it can be used in cars too. I noticed a difference immediately in the exhaust from the truck - usually I can't sit with the window down without heavy fumes. The fumes were barely noticeable and the truck is running as smoothly as I've ever seen it! Have already contacted the company directly to see how I can buy in bulk. Awesome product and can't wait to try it in my boat!

Fuel Ox is the best fuel additive I've ever used, period. I noticed an immediate increase in my trucks performance and fuel economy. An affordable solution with BIG results - win win. I cant recommend this product enough!

Recently purchased a 3 oz bottle of Fuel Ox Marine thru amazon. Your product is cleaning up my fuel moisture problems with an older (1997) Yamaha 2 stroke outboard. Even though I use rec 90 fuel I still have a bit of water getting thru separator. Your product has lessened the amount of water in the tank and helped the outboard run more efficiently.
