We use advanced technology to design VP Ultra Marine™, the best fuel stabilizer for boats. Ultra Marine™ slows the fuel aging process and keeps fuel fresh by helping to inhibit phase separation, which is an effect of ethanol. Phase separation occurs when enough water has contaminated ethanol-blended gasoline. This causes the ethanol to attach itself to the water molecules. It's important to note that ethanol is hygroscopic. In other words, it absorbs moisture from the air. As a result of phase separation, the water/ethanol separates from the gasoline in the tank and settles to the bottom. This can lead to engine knock and other serious issues. This is where a marine fuel additive can help. In fact, Ultra Marine stabilizes fuel for up to 3 year.
Another key point is that we blend our boat fuel stabilizer with a vapor corrosion inhibitor, which protects against corrosion both above as well as below the fuel line for non-ferrous metals. Furthermore, Ultra Marine contains an advanced detergent that keeps your carburetor and fuel injectors clean, prevents ring sticking, and helps eliminate carbon and varnish build-up to keep your marine engine running like new.
Use our fuel stabilizer for boats both in-season and just before you store your boat.
