Performance & Practical Benefits

A good fuel treatment can change the entire personality of an engine. With this one, you’ll notice cleaner throttle response, a steadier idle, and fewer issues caused by ethanol-blended fuel. The formula works its way through the system, loosening buildup and keeping internal passages clear. Over time, that means smoother operation, easier starts, and fewer interruptions to the days you’d rather spend fishing, cruising, or exploring.

Using it is simple — add a measured amount every time you fill the tank, and the treatment does the rest. It keeps the fuel fresh, helps maintain consistent burn quality, and reduces the risk of varnish settling during storage. Whether you’re running a pair of outboards offshore or a small skiff on a quiet lake, the difference becomes something you can feel through the controls.

Why Buy OEM

Fuel additives aren’t all created equal. This one is designed specifically with marine engines in mind, tested to handle the unique stresses and challenges that boats face — moisture, heat, vibration, and ethanol exposure. When you choose an OEM Mercury Marine part, you’re getting a formula that’s been proven through real-world conditions, not just lab tests.

It’s a practical investment, especially if you want to protect injectors, carburetors, and valves from early wear. A small amount at each fill-up can save you from costly repairs later — something any experienced boater will tell you is worth every penny.
